plants advice life is a garden

How deep do I plant my seeds?

2 ½ times the size of the seed, alternatively, read the back of the packet.

Can I plant roses in winter?

Yes, the roots are dormant, they aren't disturbed as when the sap is rising, and they settle in before spring.

Why do some of the leaves turn yellow?

That is chlorosis, caused by a difficiency in the soil. Treat with phosphates, magnesium sulphate, iron.

How difficult Bellis Perennis is to grow from seed?

These seeds are not at all difficult to grow. They require full sun to semi-shade, best sowing time is Spring to Summer; germination is approximately 15days after sowing, flowering will be approximately 20 weeks. (Kindly note these are approximate time)

When should we plant mielies?

Spring is a great time to plant mielies.

How do I apply Lawn Dressing? How much?

Lawn Dressing should be applied at the beginning of the growing season and (in South Africa) is typically applied during August & September. Kick start your dormant winter lawn by scarifying and spike rolling to improve aeration. Apply a topping of Earth2Earth weed free River Sand to level uneven areas. Follow up with an application of nitrogen rich fertilizer i.e. LAN, then cover with an even layer of Earth2Earth Lawn Dressing. Spread the Lawn Dressing evenly using the back of a steel rake, allowing the tops of your grass to show. 1 x 30dm bag covers 2 -2.5m2 Water thoroughly with a fine garden sprayer, after 2 weeks you can mow the lawn, stand back and admire a lush green carpet.

Do Aloe barberiae grow into huge big trees?

Aloe barberiae grow to approximately 12m tall and have an approximately spread of 4m.

Which herbs are suitable for Durban's warm weather?

All the herbs that we grow in Gauteng can be grown in Durban with maybe the exception of the “Sage” (this would be due to the high humidity and lots of rain)

I received a mandevilla creeper in late Autumn but decided to wait until September to put it into the ground. Unfortunately, it was a victim of frost recently. I have continued to water it even though all the leaves have dried up. Do you know if it is worth the effort? Will it grow back or should I put it in the compost heap?

The Mandevilla creeper is best suited to the frost free climate – however if protection is provided (covering of the plant) in the colder areas should be encouraged; however as the plants mature, they do become a lot hardier to the cold! I would suggest it is still not to late to provide protection for the Mandeville as July is very cold and August has those biting winds. Please do NOT be tempted to cut back the plant at this stage, rather wait until mid-September to do so. Then all the cuttings from the plant can be added to your compost heap.

My garden is green no other colour in there; I have big trees and very dense shade; How do I go about to bring colour into this shady environment?

In a shady environment you could suggest (Annuals – new guinea impatiens, begonia’s, foxgloves, mimulus, or lobelia) and (Perennials – plectranthus, clivia’s, azaleas, viola’s or lamium ) I would introduce shade loving seedlings for your summer garden, examples would be: begnoia’s, impatiens or for something more permanent plants like plectranthus, fuchsia’s and azalea’s. However, do remember that feeding is most important in a shaded area, and if possible try and cut back some of the branches on the taller growing shrubs and trees.

What will you suggest for clivias, what kind of ground, is compos alone needed?

Clivias like a neutral soil so I would suggest to use only compost however I would suggest a regular feeding of 3.1.5. A further point to remember, when you water rather water deeply less often that a light sprinkling. Clivia’s like shaded conditions and well composted soil to grow in. It would be great to plant them with a bit of superphosphate or bone meal and give them a granular feeding of 515 or 315 in August just prior to their flowering season.

I have planted Gerbera Daisy seed in pots and in the soil but they don't seem to be coming up? Is it just still too cold or what – as everything else has come up, so I am finding this really weird. Will they still come up?

Just make certain that you do not allow the seeds to dry out, and also I hope you have positioned them in a semi-shade position and not full sun – other than that I can think of no reason why they do not germinate. (I have tried to grow these seeds myself and very much to my surprise did not have a great success rate? No too sure)

Please let me know what is the best veggies to plant in April in Gauteng South Africa

The best veggies to plant now are Rhubarb, Lettuce, Chives, Spring Onions and Onions, Oriental Veggies, Cabbage, Cauliflower, Spinach and Swiss Chard ... just to mention a few!

I want to grow vegetables in a few containers as my garden is too small, but so far had very little success, even with carrots and beetroot. Onion seeds never seem to germinate. What am I doing wrong?

Carrots are best grown in the ground unless they are in a large deep container/pot. The position definitely sounds great as veggies need at least 5 hours of sun a day. As for the soil, if you are planting in pots, make sure you have a good mix of compost and potting soil (50/50). Ensure that the pots are of an adequate size and allow for good drainage. Feeding is of the utmost importance, you can pick some up from your local accredited garden centre.

I planted some peppadew seeds given to me by a friend. Two plants survived and now have a few fruit that looks exactly like minature green peppers - not at all like the red peppadews you buy in a bottle. Must I wait until it turns red and can you eat them raw?

There are many variations on the so called pepper dew – however they all need to turn red before picking. They can be eaten raw or pickled

I have Sage "Midnight" in a largish container, but it does not look happy to me. I do feed it but it makes no difference. I wonder if it would be better in the ground. It is in full sunshine.

Sage will grow quite happily in both a pots and in the ground. Good to hear it is in full sun - as this is what it enjoys. Sage is very sensitive to over water (I suspect this is what it can be) allow the plant to dry out completely before the next watering! (And in between watering’s)

Struggling to get Verbena b. (big tall one in the pic) going this year, made another sowing today and put it in a zip lock bag, hopefully this time...

Verbena seed like to germinate in dry conditions with limited light exposure. We water the trays after we have sown the seeds and 5 days later give them there next watering. Verbena seeds generally prefer a dryer condition when I plant them I would mist them every third day (with a spray bottle) as opposed to most other seeds, which I would mist daily!

Canterbury Bells, I have lost the seed pkt, how tall do they grow, I have some ready for transplanting.

Canterbury Bells grow to between 50cm and 60cm.

What plant would be best to make a bonsai tree?

These are just some shrubs are great for bonsai:

Acers (maples)
Cape May
Pines – Cedrus, Cypress, Juniprus

Are there small citrus trees available these days? I'd love to have one or two but I have a tiny townhouse courtyard. I'd love to have a naartjie or mini lemon tree. The ones I remember from my parents' garden were huge.

You certainly can get small lemons and also naartjie trees and they grow most successfully in pots.

Generally all the fruit trees are large. There is the Calamondin Fruit tree which is ornamental and not edible. This tree stays short and is very good for pots.

My lemon tree has seen better days, surrounded by paving it is not doing so well although I guess it is at least 25 years old!

I think 25 years is sufficient for a lemon tree – you might consider replacing it?

I wasn't successful with strawberries a few years ago... will have to try again. Any advice?

Firstly, strawberries are gross feeder and require regular feeding, also be careful not to allow the leaves to just lay on the ground, I always like to put a layer of either mulch or some type of support to raise them off the ground. Do ensure they get a position that gets a lot of sun. Remembering that strawberries last for three years and then it is advisable to take cuttings from the Parent plant to replant.

I have a very small garden and would like to plant a tree that is low maintenance and does not grow larger than 2m. It also needs to be planted next to a wall so it cannot be destructive with its roots.

There are very few small trees that only grow to about 2m (most grow to about 4m)– maybe you should rather consider getting a tall standard shrub. Small growing trees would be: Calpurnia, Acers and Noltea.

I am wanting to plant out the poinsettia I bought for indoors over the Christmas season. It is a healthy strong plant! Can I plant it is a sunny spot in my garden?

Transfer the poinsettia to a shady spot in the garden with sufficient light. It can then be transferred again to a semi – shade once it has been established.

My Avocado (from a pip) is about chest high but some leaves show some burn marks. It is near our compost heap - also it seems to have some water run off around it so may be a bit wet. Can I move it? And what advice do you have? Does it have a very long tap root?

The brown leaves on the plant can be various things. It would be best to visit your nearest garden centre with samples of the leaves. Avocados have a shallow aggressive root system. If you would like to move it, move it on a cooler day or preferably during winter.

How do I know when cucumbers are ready to pick? Also looking for the name for the English cucumber seeds?

The botanical name for them is Cucumis sativus , variety English . On the back of the seed packet ail be instructions and guidelines as to how many days from germination before they are ready. They should be dark green colour, firm to touch when squeezed gently.

Can you plant natal lavender tree in Cape Town?

Yes you can definitely, it is a beautiful indigenous tree.

I live in Kakamas, Northern Cape (near Upington so very hot and dry) and am looking for a potted creeper to cover a wire arch in front of my home. I saw the Jasminum polyanthum and fell in love with it but fear that it wouldn't survive our climate. Any suggestions? Unfortunately it has to be potted.

You can definitely plant the jasmine. It is a fast growing climber and with regular feeding and proper watering it will flourish. Just ensure that the drainage in the pot is properly.

We live on a farm. Summers very hot but winter months there is always frost. What plants/flowers can I plant that will survive all year round? Or that will grow again in summer? Like Cannas? Also what flowers (also that can survive frost) can I plant between my roses?

Plants like Erigeron, Dietes, Chives, Ceratium (snow in summer), Lavender, Brachycome (swan river daisy) and Felicia.

I seem to have a plague going through my gardern. It started with one Papaya tree where the leaves started curling. Curly leaves all over, even flowers. All my strawberries, potatoes, and several sessions of tomatoes died! I cleaned out everything, burnt everything, planted new tomatoes. When they were 1,5 meters tall, they suddenly got brown spots and died. Same with potatoes. My strawberries leaves turn purplyish, brown leaves, dark to black fruit & die! I sterilised many things including growing medium with chlorine, checked Ph, but it keeps coming. It is now winter and our main veggie time. (cooler weather) Hoedspruit. I am 99% sure it is late blight or rust. I sprayed with many things, but once it starts nothing stops it. I have photos, Can I buy seeds of resisant varieties? In between all this destruction, my lettuce grow like crazy, no problem! I plant green peppers, lettuce, tomatoes,. beetroot, strawberries and brinjals for ourselves.

It could be that your soil is ‘clay’. Clay is a very heavy soil and does not drain sufficiently and can bring about a lot of various problems; in addition it could be a water problem (maybe too much water). If your soil does not drain properly it is always a good idea to dig in some river sand which will certainly help! If it is a fungus I would then suggest you bought a product call ‘BRAVO’ which is excellent for all types fungus. A further point is to always check the date on the packs of seed that you purchase to ensure they are not past their sell by.

I am looking to get some Peony shrubs but I don't know if they even grow in SA. Do they grow here and where would I get them? Are they known by a different name here?

Yes Peonies do grow here. If they are not available at your local nursery, you can try Hadeco Bulbs at, or Plant Farm in Pretoria at

I would really like to grow some of this white sage for personal use. Is it possible in Johannesburg and where could I obtain the seeds/plants?

It should grow in Johannesburg. Try Bridget Kitley Herbs in Stellenbosch. Her e-mail address is

Can you please let me know when will be the right time of the year to plant dahlia bulbs?

Dahlias can be planted from the beginning of September through to November.

Please take me through the process of planting grass,sugar beans, potatoes,pumpkin, fruit and vegetables.Tell me what kind of the fertilisers I need to use and the chemicals used to destroy the insects and the unwanted plants or weeds.

To plant grass (lawn) you need to clear the area of any weeds, dig over the soil, break up the sods and rake it flat. When planting, add Bonemeal or Super Phosphate to soil and dig in lightly. For vegetables dig over the soil and add well decomposed compost and a fertiliser, like Wonder Planting and Vegetables:2:3:4. Water well once seedlings/seed are planted. If seedlings are eaten use Cutworm Bait. When planting fruit trees add compost to the soil when you have made your planting hole, also add Bonemeal/Super Phosphate. Once the trees are growing fertilise with a 3:1:5 fertiliser. Using a herbicide would depend on what kind of plants or weeds you want to destroy. Go to your local nursery or garden centre and ask them.

We have recently move from KZN to Mossel Bay in the Western Cape. I have done nothing in our garden as yet because I dont know much about fynbos. We face a green belt. However, my question regards our neighbour's tree. I think it is called a Brazilian/Australian pepper tree? Is it an invader and in what category?

The Pepper tree Schinus terebinthifolius is a declared invader in category 3 and although new trees may not be planted, existing ones may remain.

I am wanting to grow dwarf fruit trees. What are their names, where can I find them and what should I be looking for?

You can keep fruit trees small and compact by pruning them. Planting the fruit trees in containers will also inhibit the growth. Fruit trees you can try are citrus like Lemon, Orange and Naartjie. You can also try Santa Rosa Plum and Fantasia Nectarine.

Do sunflowers bloom in February / March? And if not, when is their season? Thank you!

Yes sunflowers do flower in February/March.

My 1yr old potted roses sprang into life in September after their pruning in late July. They are floribundas. The central bloom turns brown and dies before opening, and then the other buds follow suit. They don't seem waterlogged. What should I do?

The buds have a fungal disease. Cut off the buds and spray with a fungicide like Bravo. This can happen if the weather is damp and rainy. You may need to spray regularly for a while to get rid of the fungus. Do check that the soil does drain well in the container.

I want to know when to plant these so that they all bloom together: hollyhocks, foxgloves, delphiniums, lupins and Canterbury bells.

If they are all sown in late summer or early autumn you should be able to have them bloom late spring or early summer.

I would like to know what trees give nice shade (might want to be deciduous) and will thrive in Virginia in the Free State, and a Pen Root System. 2) We are struggling terribly to make vegetables grow here, the sun burns almost all dead. Green beans the season beautifully grown, but when feeding the finches all the flowers on. If we have a framework with a veil on, the vegetable garden devise, what degree (or colour) should be the shade cloth?

There are very few trees that have a Tap root system. These trees are indigenous and have a smaller root system. Try Dombeya rotundifolia (deciduous) or Heteropyxis natalensis(deciduous) or Buddleja saligna. It is difficult to grow vegetables in the hot sun and the birds can be a problem. Try covering your framework with shade cloth that is 40 percent.

Which vegetables will do well in my area (Centurion) when planted?

Vegetables planted now that will do well are Beetroot, Carrots, Spinach, Cabbage, celery, lettuce, radish, onions, leeks, turnips.

Overwatering will not cause the leaves to curl - the leaves will start going yellow and will fall off if overwatered. There is a tiny insect unseen by the eye that can cause curling leaves. Spray with Metasystox.

Good afternoon. I hope you can offer some advice.  We are moving abroad in a few months time and my children want to take cuttings of the plants in our garden which were planted in memory of pets we have lost. We have a Callistemon and a Polygala Myrtifolia.  If you could advise of the most foolproof way of getting a cutting and ensuring its growth I would be very grateful.

Cut a healthy branch from the plant. When making the cutting, cut underneath the bottom leaf node and strip the bottom leaves, at the top cut any flowers off above a leaf node and cut the leaves shorter, dip the bottom into a rooting hormone powder(available at Nurseries and Garden Centres) and put the cutting into a well drained soil mix, water and put the cuttings into a warm place. Keep damp, do not overwater.  For the Callistemon take a 5-6cm cutting and use a rooting hormone powder for hardwood cuttings. For the Polygala take tip cuttings 4-5cm long and use a rooting hormone powder for medium wood.

Having a problem with my Protea Repens, never flowered for 2 years now. I broke off the flowers when it dried after the last time it flowered, so I dunno if it could be from that or what. Western Cape

The Protea flowers when dry should be cut off so that it can get new growth. It should be planted in the sun in well drained acidic soil. You can feed it an organic fertiliser. Do not dig the fertiliser in, just spread it on top. Water well, but do not over water.

I have moved to a property with lots of roses. I would like to move them. Is it advisable to replant roses and what is the best time to replant them? Gauteng

You can replant roses successfully. It is a good time to do it now in winter. Prune the bushes before transplanting.

I have spent hours trying to find out which trees lose ALL their leaves at the Beginning of winter, in a short period of time. The reason for this is that the heat of the home should not b negatively affected.... Every article mentions Lavender -semi deciduous,(and of which I have planted 5 in close proximity of each other, and which I wrote to you about, but which will not affect sunlight), Pompon- loses only at end of winter , Wisteria- loses leaves late,  etc etc.... most of the others I have read about are evergreen.!
That leaves me with the Wild Pear and the Parsley: I have no knowledge of when total leaf loss occurs or whether it does. I do like vase or umbrella shaped trees but this is of less importance.
 Area is Midsream Centurion. Very hot summer, cold winter.... trees will have lots of sunlight.
 Also, when covering young trees with frost cloth, should the entire tree b covered or only the stem?

Both the Wild Pear and the Parsley Tree are deciduous and total leaf loss will depend on how cold it is in autumn.

Which vegetables can I start to plant now in winter in North west? And how do I encourage cabbage to form a head instead of just getting taller and taller?

Onions, peas and Swiss Chard. Cabbage can ‘bolt’ if they have too much hot weather. It is better to plant them in cooler weather.

How do I cut back my acasia tree's roots when they become pot bound...?

When you have removed it from the pot cut the bottom roots shorter by a couple of centimetres. Be careful that you do not cut too much of the taproot. Put fresh soil in when repotting.

My vision for my garden is to attract as many insects and birds as possible and to play with a variety of colour. In my front yard I’m working towards a semi shade, forest like garden feel (with a Pyracantha, 5 Celtis africanas, a small Olea europaea (Olienhout), a Buddleja salinga and a Correa alba).
My back yard is sunnier (with a lemon, peach, 3 small fig trees and a small Celtis Africana tree. A Milkweed (specially for Milkweed butterflies), Wild Dagga, Black Eyed Susan’s, Agapanthus and Arum Lilies.) – All my grey water goes into my back yard. And we have a borehole.
So my questions are:
1. Will a Carissa Macrocarpa grow in my front yard (semi shade)?
2. Can you suggest more plants that I can plant (keeping Bloemfontein climate in mind).
3. What are the best fast growing bushes/ hedge to cover a fence. Free State

1. Yes it would grow in the semi shade.
2. What about Aloes, Tecomas and Vygies.
3. Freylinia tropica, Dodonaea purpurea, Tecoma (Buddleja saligna and Correa alba would work too)

The best time to grow bush beans in S.A.? Gauteng

You can start growing bush beans in August in Gauteng.

We are downsizing and when we sell our house (sigh) will be moving to a flat with a balcony only. However, I am already slightly involved the gardens for the entire apartment block. The garden is very shady; the bed which has the most sun is mostly filled with agapanthus and the other similar ?indigenous fail-safe plant which gets white flowers once a year. I am planning to get that bed dug up, composted and filled with a range of indigenous and other plants such as perennial basil which the bees adore. I already have a large crassula tirucali and a grey jade plant (crassula ovata), some red and yellow shrimp bushes (beleperone), cats tail asparagus fern which I’m planning to put into the bed.
Any other suggestions? I have some donated dahlia bulbs. Gauteng

Try some Dietes grandiflora & bicolor, Gazanias, Lavenders. Rosemary, Aloes and Vygies

Gazanias and Dianthus do best. Lobelias and Petunias need protection from the wind. Begonias need shade and protection from the wind.

Several lemon trees later, I eventually tried one in a pot. It grew fantastic, new leaves, buds, flowers, but fruit falls off turns yellow. Lately it has lost all leaves at the top, leaves are curling, turning yellow, falling off. I have not been watering, because of the rain, soil is damp. I did feed with Epsom salts, 3:1:5, drainage is good, a little bit of 2:3:2 as well. I have lemon trees in Bellville, but after many trees from Stodels/Cape Garden Centre, no luck. Can you advise? Western Cape

Make sure that the soil drains well. A lemon likes well drained compost enriched soil. It likes to be watered well but must not be over watered. If the soil is wet deeper down it will cause yellowing of leaves and dropping off. If the soil is damp on top and dry deeper down it needs more water. Do not feed the tree while it is under stress.

My anthuriums' leaves are dried out in some spots and I only put them in the sun for a few minutes when cleaning my kitchen. Could you tell me what's wrong? Lusaka, Zambia

Anthuriums like humid conditions and the soil must be damp and well drained. They do not like direct sun. If the air is too dry and the soil is dry it could cause dry spots.

I discovered your website whilst doing some research on protea plant care.
I live on the French Riviera and have had a Protea Cynaroides little prince since the end of May.
I have carefully read and considered the rules and yet my poor protea is just shrivelling up.
First she started by getting yellow leaves, then they went brown and the flower has stopped opening and is totally drying out. I've put her in a shadier place now, my so called hospital where I put those plants that didn't succeed elsewhere.
I hope she can still be saved!!!

Proteas grow in well drained acidic soil in the sun where there is air movement. They need to be watered well, but not over watered. The problem could be drainage or over watering.

Can one transplant a camellia and if so when is the best time? We live in plumstead, Cape Town.

I have a Chinese jasmine and the smell is heavenly. If I were to plant an indigenous jasmine, which one would it be, because I want the smell! Gauteng

Both Jasminum multipartitum and Jasminum angular are sweetly scented.

My Bearded Iris are not flowering. Very sparse leaves. What can I do? Eastern Cape

Old or overcrowded clumps need to be divided. Plant them in the sun in well drained alkaline/neutral soil. When planting use Bone meal/Super Phosphate. Feed with 3:1:5 fertiliser. They only produce flower stalks on new rhizomes.

The leaves on my Clivias are brown and have been eaten by some insect, I think.  It seems to go right into the bulb. I have no idea how to get rid of this insect or bug.
 If treated, will the bulbs recover?

It is the Lily Borer eating the leaves into the bulb. Treat with Karba Spray. If the worms have not destroyed the central part of the bulb they should recover.

I live in Pretoria. I have a Protea mundii. Will it survive my climate? I have borehole water so keeping it wet is no problem. Gauteng

It should grow. Plant in well drained acidic soil. It likes air movement around it. Water well but do not over water. Check that the borehole water is not too alkaline.

Would/could Clivias live in a hot-house? 
I have been given some Clivia seed pods and don't have any trees in my garden for shade, so Im wondering if I plant them in a pot and let them live in my hot house, will it work?

Yes the Clivias would work in your hot house. Check that the soil is well drained. Water well but do not over water.

When is the season for Hyacinths? Gauteng

My pansies in containers were doing very well until I noticed they are droopy, the leaves are yellow. I think I over watered them. Will they recover or should I kiss them goodbye? Gauteng

Sorry if they are droopy and have yellow leaves they could be over watered and they will rot and die.

Will a camellia thrive in an area which gets some sun in summer but only shade in winter? Which variety would be best for such a situation? Gauteng

Dappled shade from mature trees is ideal for most, though some are more sun tolerant than others. Too much shade reduces bud formation, whilst excessive heat and sunshine scorches fine surface roots and flower buds. Also keep their root zones cool through the heat of summer with a thick layer of mulch in the form of leaf mould, pine needles or pine bark. If the sun isn’t too hot and too long it should be fine.

I planted alyssum about 6 weeks ago and it is looking beautiful. Can you advise me as to how long it will last. I need to have it looking good for 22 October and am not sure whether I should pull it all out and replant new seedlings or not. Likewise for some violas(mini pansies) that i also planted??? KZN

Both the alyssum and the violas should still be fine and looking good. Remove dead flowers from the violas so that they can produce new buds.

How does one care for azaleas? Should they be pruned? And is left-over coffee and grounds good for the soil? Limpopo

Azaleas like slightly acidic well drained soil. They prefer to grow in dappled shade. They are shallow rooted, so mulch with pine bark. Water well but do not overwater. You can prune back the plant after flowering to keep it in shape and to remove dead branches. You can use the coffee grounds to mulch the plant.

I am enquiring about my valencia orange tree which I bought 7 years ago. For the past 2 years it's produced small oranges which would all fall before they could grow big. But this year it's produced lots of oranges which they all grew to a normal size and ripe, but the problem they were so sour as if they were lemon with lots of seeds, with a grapefruit flavour. What can I do to make them sweet? KZN

The orange needs to grow in sun and needs regular water, do not let it dry out. Mulch the tree to conserve moisture. Fertilise with a 3:1:5 fertiliser in July, December and March. Also give the tree some Magnesium sulphate in those 3 months. 

I was wondering if you could offer me some advice on possible treatment/s please? I have been busy with a large Pomegranate Bonsai and of recent noticed a lot of wilting branches. Upon closer inspection I noticed several small holes I could not find any sawdust at the base of the trunk. I did however notice a few tiny wasp like insects in my garden recently. KZN

Try spraying the tree with Garden Ripcord.

One of my Abutilon plants seems to have died after about 8 years and I am not sure whether to pull it out or try to revive it. I have cut it back and fed it but it does not seem to be responding over several months. The other one is very prolific and needs pruning but I am quite nervous to do this after the other disaster. Western Cape

Early spring is a good time to prune. Prune back dead, diseased and damaged branches. Prune the bush back but not more than a third.

We have 2 lavender plants in small pots. We went away for 3  days and when we got back the plants are wilted. I assume from lack of water. Will they recover and what should I do with regards to watering? They are new plant received last week Wednesday. We live in Johannesburg and was quite hot this past weekend

Have they been planted out? If so they should recover, Water well but do not overwater. They like to grow in well drained compost enriched soil. If the tips are still wilted, cut them back to encourage new growth.

We live in the Wilderness & have some lovely large Tree Fern specimens, which have seemed happy & given much pleasure.
 However, after a particularly hot humid summer & a cold dryish winter this year, they seem to be affected by some sort of borer or worm.
 The fronds turn brown & dry up fairly quickly after spreading. I did fertilise them this year with the “new” bounce back!
Any suggestions?

Too little water if it is too hot and dry will cause the fronds to go brown, as well as if it is too cold and windy could cause the leaves to go brown. Too much sun and too much water could also cause the leaves to go brown.

I have a few Clivias which are planted in pots. Some of the leaves are yellow with brown tips.  What am I doing wrong?
 Furthermore, I do not have much shade in my garden close to the house, but would like to plant the Clivias in the garden. We have a large Pine tree at the bottom of our garden, can I plant the Clivias under the Pine tree? Furthermore, we live in an area where there is quite a bit of frost in the winter. Should we then cover the Clivias during the winter? Gauteng

The Clivias could be getting too much water. You can plant them under the Pine tree, but you must add compost to the soil and fertilise the plants. The Clivias should be protected under the Pine Trees.

Can the Bella Red Mandevilla withstand the windy Cape? Norma, Western Cape

It is fairly wind hardy, but do protect it from the worst winds.

I bought some petunias about 2 weeks ago and today they have shrivelled up and look as though they are dying. What could have happened? Gauteng

If the plants were dry and it was hot they could have been damaged.

I'm living in Sydney, Australia.
I bought three blue Felicia plants 5 years ago and cannot find them anywhere now.
They don't self seed, so is it possible for me to collect the seeds myself after flowering and plant them? Or, would they strike from a cutting? They are the most hardy and pretty little flower for our hot climate in Sydney! 

They grow easily from cuttings. You could collect the seed and try that too.

I live in the PE region and would love to plant some olive trees. I was told out climate here is not conducive to successful olive tree growing. Could it help if blossoms on trees are covered in bags? Or if some trees are planted in a greenhouse with regulated temperature? Could I plant olive trees as windbreakers for ornamental use and which cultivars can be planted as windbreakers? How fast does an olive tree grow? Eastern Cape

Olive trees do grow in the PE region. Plant in  well composted soil and water well until established. You can use them as a windbreak. Mission is a variety that grows well and bears well.

I bought 4 fynbos plants (2 being the yellow and red pincushion) Leucospermum cordifolium in Port Elizabeth to plant in Boknes Strand/Cannon Rocks area where we live. However a landscaper said that they would all die as they are not indigenous to our area because of the alkali soil yet the soil measures in some areas at between 5 & 6 acidity. Please advise how one can change the soil if alkali to acidic. We have built new in Boknes so I don’t have a garden and trying to establish one putting in trees and shrubs on a shoestring budget. I really don’t know what grows in the area so trying my hand in everything as the area is also an extremely windy place.

The Leucospermums like to grow in acidic well drained soil. Add pine bark compost or peat to the soil to make it more acidic. Also mulch the plants with pinebark. They prefer to grow with air circulation around them so they don’t mind the wind.

I live in an area where Litchi trees grow very well,but for some reason no litchis trees grow in the yard i live in.I was given a litchis plant recently by a friend so i decided to try and get it to grow,at one stage there was some hope but that soon went away,now i just have a stem in a pot. Please help. KZN

Litchi like to grow in the sun in well drained soil. They do not like wet feet, so do not overwater especially in the cooler months. They need regular watering in the growing season.

What chances has it got of recovering, and is there anything I should do?

The chances of it recovering are good. Cut all the damaged and dead wood out and cut the rest shorter, it should soon send out new growth then.

Scratch the stems and if they are still green, trim the vine back and water it. Do not feed it. If the stems are dry it is dead.

leaves on the inside of the "balls". Still growing leaves on the outside, but not looking good at all. See no sign of pests. What could be the reason? Is there any way leaves will grow on the inside again? Western Cape

They could be losing leaves if growth is strong and no light gets to the centre. Trim the balls, cutting out any dead little branches, hopefully you will get some new growth again.

I've bought a few patio Pot roses a while ago, because of painters in our complex never replanted them into larger containers. I do experience a lot of problems to keep them alive and nice. Got them inside the house at the moment, they do get white fly, etc on them, spray them with diluted dishwashing liquid. Found that the young soft leaves burn then I have to cut them off. Did find a big white worm in the soil as well. Some of the roses stems turned black and it look like it is dying? Why? I do feed them with Seagrow, spray the leaves as well.
Please help. They are very sensitive to direct warm sunlight, even the wind outside, do put them near the window in the sun.

If grown indoors they need bright light/sun and air circulation. They need to be watered well, do not let them dry out, but do not overwater. If you want to use a liquid fertilizer rather use Nitrosol or Multifeed. The black stems could be a fungus treat with a fungicide, if very bad cut the stems back to the green.  Do not spray the plant when the soil is dry as that could burn the young growth.

Took over a very neglected garden with our new house in Klerksdorp and I have what I suspect is a naartjie (satsuma mandarin) tree in front garden. It's full of fruit, most still green turning orange, but the orange ones are very sour and not peeling as easily. 
Is it too early for them to start ripening? Why are some already turning orange and falling off the tree?
Is it too late to fertilise and water regularly? (Late May) Is there any way to make the fruit sweet now?
 Should I just see what fruit is edible this year and how can I make sure we get nice fruit next year? North West

It is not too early for naartjies to start ripening now. They are probably falling off because they have not been watered regularly. They need to be watered well and regularly (especially in hot dry weather). Apply 3:1:5 fertiliser in July, December and March.

I have an Aloe Porcupine purchased from Blackwoods May 2016. I replanted the very prolific flowering specimen into a larger pot and have again got flowers.

The pot enjoys good sunshine and I live in Durban North. KZN

The Aloe likes the sun which you are giving it, it only needs to be watered when the soil is dry. If you feel the plant is too full for the pot you can split in late winter or early spring. Locate pups (plantlets) from the parent, see that it has roots, cut away(or break off) from the parent. Leave the plant to dry out (the Cut bit) for 2 days before planting. Do not water until roots have taken and begun to grow (about 2 weeks)

Do you have any tips on propagating tamarillos (tree tomatoes) from branch/trunk cuttings that don't have any leaves? I've got a really tall, spindly red tamarillo that's about a year old in a large pot. It only has leaves right at the top (looks a little like a palm tree at the moment!), so I can't really prune/lop to encourage branching, as it's already taller than I planned it to be. Before giving up on the poor thing, I was hoping to try making cuttings off the trunk. 
I know that one can get tamarillo cuttings to successfully root if there is at least one leaf on the branch and a couple of nodes where leaves used to be. But do you know if it'll take if it's just the stick without any leaves? Oh, I live in George, if that's of any relevance. Western Cape

You should be able to take cuttings from the trunk/branches and they should root. The cuttings should be at least 20cm long with 3 leaf nodes in the soil mix. The soil should be a light well drained mix. Keep the cuttings in a warm spot to root. Keep damp but do not overwater.

If this is a way to go, can I do this now, or better to wait until the end of middle of August?  Your help and input appreciated – the same applies to my plumbago which I love to pieces. Eastern Cape

You can cut them quite short and they will send out new growth. Do remove any dead wood on the inside as this opens up the plants and helps with the new shoots. You can do it now if it is not too cold in your area otherwise wait until spring.

I live in Howick, KZN and my son has given me 2 Powderblue Blueberry plants to grow in my garden. Please would you provide answers to the following:

· Do they need full sun or partial sun/shade?
· What soil mixture should be used?
· What plant food should be used and when should feeding take place?
· Any other information that I will need to generate fruit?

I replaced my lawn with Dymondia last year & there are patches that are turning white & then dying. There are also patches turning brown. I don't know if it's fungus or insects. I do notice lots of snails when it rains & at night but I have pets so don't want to put poison down. There is also lots of bare soil where the Dymondia hasn't spread yet.

Would like to know if one can replant the little seedlings that form underneath the Yesterday Today and Tomorrow plant with their little roots? Or is it best to propagate the plant or plant from seeds? Gauteng

You could plant the seedlings if transplanted carefully, otherwise cuttings is easier

We have recently moved into a newly built house with a fairly small garden. We had a pool built in the corner and the builders planted a row of "joburg gold" trees about a metre away from the pool, touching the wall between our property and our neighbours' property. I absolutely love the trees but I am concerned that the roots will damage either the wall or the swimming pool. Should I remove the trees and plant something else or will I be able to leave them where they are? Pretoria East

If you are able to prune the trees and keep them small it shouldn’t be a problem. 1 metre from the pool and close to the wall does seem very small.

I've tried to grow Hypoestes phyllostachya unsuccessfully in Joburg. Can you help? And are they frost tolerant? Gauteng

They are not frost tolerant and will die in the cold, treat as an annual for the summer garden.

My lawn has patches, how to treat it and make it green. Eastern Cape

Try fertilizing with Bio Ganic Lawn fertiliser.
