September in the Garden September Check List

Posted on: August 27th, 2020 by Shahnee Stockigt No Comments

September always kicks off with Arbor Week and this year it officially kicks off on Monday 31 August and runs until Friday 4 September.

  • Common tree of the year is the Cape ash or essenhout Ekebergia capensis, which is a stunning, lush evergreen tree that grows in many parts of the country, except the regions with heavy frost. It has fragrant flowers and its fruit attracts many birds and mammals.
  • The second tree of the year is the baobab or kremetart Adansonia digitata. Also known as the upside-down tree, it dominates the Limpopo landscape with its swollen trunk and limbs. It yields the coveted cream-of-tartar fruits and can be grown in frost-free areas.

Tip: The initiative of Arbor Week is to promote the greening of communities. Celebrate Arbor Week by planting either of the above two trees or any other trees or shrubs. If they are indigenous and water-wise that would be a bonus. It is said that Life is a Garden … so create yours and celebrate the plants you love most.

Sow edibles

There is a multitude of both flowering and edible seeds that can be sown now. Visit your local GCA Garden Centre to see the range and perhaps consider one or more of the many tomato varieties available to sow now:

  • Roma – Firm, fleshy with few seeds. Great for canning and cooking. Fairly long shelf life. High yields, it requires a trellis or stakes.
  • Heinz – Large fruit with rich tomato flavour. One of the first tomatoes to be used to make Heinz ketchup. Requires a trellis or stakes
  • Cherry tomatoes – Several on the market. Bite-size and has a delicious flavour, is small and round and can be eaten whole in salads.
  • Cherry yellow pear – An heirloom variety with small yellow pear-shaped fruit.
  • Oxheart – Another Heirloom tomato with enormous heart-shaped fruit. Mild, sweet flavour. Requires staking.

Tip: There are rainbow coloured cherry tomatoes such as Green Zebra, Clear Pink, Black striped and even Green Sausage seeds available for those of you that want to be a little different and create a talking point at the dinner table.

What to Plant

Our indigenous Clivias are favourites worldwide and it’s not difficult to see why when they bloom in September.

  • Beautiful trumpet-shaped flowers
  • Clivias do well in pots.
  • They readily multiply and spread to fill shady beds.

Tip: There are many different hybrid Clivias. If you are a Clivia fan or would like to see some of the more unusual Clivias, take some time off and visit a local Clivia show this spring.

What to Spray
  • Spray your fruit trees preventatively every 2 weeks for Codling Moths and Fruit Flies.
  • Only start spraying after about 80% of the flower petals have dropped so that you give the bees enough time to pollinate the flowers.
  • Make sure you alternate the insecticides you use so that the fruit fly cannot build up a resistance to anyone insecticide. Ask your local GCA Garden Centre for assistance.

Tip: It would be wise to use spraying in conjunction with a fruit fly trap.

What to Feed
  • Spring is the correct time to feed the plant roots to activate good root growth at the beginning of the season. Good roots make good, strong plants. This is most applicable to lawns and leafy plants.
  • Flowering plants, shrubs and fruit trees will benefit from early season fertilising too. Your local GCA Garden Centre can advise you on the best fertilisers to use.

Tip: When you ask your local GCA Garden Centre for advice be sure to mention your preference for either chemical or organic fertiliser.

Bedding plants

Focus on annual Phlox

  • The flowers are mostly flat and star-shaped in a variety of colours including violet, pink, blue, red, white and cream. Flowers are fragrant and should be deadheaded regularly to encourage more flowers.
  • Phlox prefers full sun to light shade, require good drainage and well-composted soils.

Tip: Phlox are easy to care for as long as you understand that they prefer moist soil and that drying out too much hinders growth and flowering.

Balcony or pot plants

Cape daisies or Osteospermums:

  • Indigenous eye-catching flowers in a range of colours.
  • Easy to grow.
  • They flower freely and love to cascade over the sides of pots or troughs.

Water-wise

Its heritage month so why not brag about our own indigenous plants a little?

  • Cape honeysuckles Tecoma capensis:
    • Flower mostly in autumn but sometimes flower sporadically throughout the year.
    • Can be used as a formal or informal hedge.
    • Flower colour ranges from red, yellow,orange and salmon.
    • Attract birds and butterflies.
  • Both the kingfisher daisy (Felicia bergeriana) and the blue marguerite (Felicia ammelloides) have:
    • Striking small blue daisy-like blue flowers with button-like yellow centres.
    • Both have variegated forms and are all gems in the front of garden borders or in mixed containers.
Inland gardening

Spring fever is in the air, here are a few things you may forget to look at in the garden:

  • New beds on a slope and newly terraced areas should be planted up with groundcovers so that they can bind the soil before the summer rains.
  • Consider beautiful arches, arbour benches, obelisks and other decorative items that will add a new dimension or feature to your garden.

Tip: Spring is the time that garden centres feature new and exciting products as well as loads of explosively colourful plants – do yourself a favour and go into your favourite GCA Garden Centre…. you will not be disappointed!

Coastal gardening

The bulk of spring planting is almost behind us and that gives you a little breathing space to look at:

  • Removing any rust on metal features in the garden before the summer rains start, (excludes the Cape winter rainfall region).

Tip: Baking soda and steel wool are a home remedy you may want to try.

Spring brings new beginnings September in the Garden

Posted on: August 30th, 2019 by Shahnee Stockigt No Comments

September is here – the sun is getting warmer, and our gardens are showing new signs of life. Spring is the perfect time to look at your garden with fresh eyes, make some changes and plan for the summer months ahead. 

Arbor week

The 1st to the 7th of September is national Arbor week in South Africa - a time when South Africans of all ages are encouraged to celebrate the beauty and importance of trees.

The trees of the year for 2019 are Common Tree of The Year: Sclerocarya birrea Marula Maroela. Rare (Uncommon) Tree of The Year: Philenoptera violacea Apple-leaf, Appelblaar. 

The month of September is the perfect time to plant an indigenous tree in your gardens - at home, office parks, and schools – especially as we are currently losing many of our trees to the invasive Shothole Borer.

What to Sow

During summer months, having fresh salad supplies ready to pick from your garden is a win! September is the time to sow lettuce, spring onion and tomato seeds, ready for your summer salads.  

  • Lettuce can be grown in a sunny garden bed. Most varieties are quick and easy to grow and produce a harvest within a month or two.  The loose-leafed varieties are the most practical because you can harvest the individual leaves for up to three months before replanting. Others, like the butterhead or iceberg, are picked when the heads form, so it’s best to sow seed at 3–4 weekly intervals to have a constant supply. Use a fertile, well-draining soil medium and space about 30cm apart to allow for good air circulation. Keep the soil evenly moist at all times — drought stress can cause a bitter taste. 
  • Spring Onion can be grown in sun or partial shade and prefer rich soil with compost dug in. Space seeds 10cm apart.

What to Plant
A perfect plant to fill your shaded gardens with bright, long-lasting colour in summer is Impatients.  The new Beacon Impatiens (Impatiens walleriana) offers high resistance to downy mildew and won’t collapse due to this destructive disease. For lasting colour plant your Impatients in fertile, well-drained soil in shade or partial sun. Beacon Impatiens are also great for baskets, window boxes, and containers, but will need a steady supply of water. 

What to Spray
You know that spring has arrived when you smell the Jasmine and see the orange blaze as the indigenous Clivia’s start to emerge from their buds. Watch out for the lily borer in your Clivia’s. The caterpillar and their larvae damage the stems and leaves and if left untreated will cause a lot of damage. If you see any traces of larvae or damage to the plant, apply contact insecticide every two weeks to control. 

What to Feed

Rejuvenate your lawn in September by applying a lawn dressing - a mixture of well-balanced organic matter and weed-free soil. A thin layer should be spread on established lawns to level an uneven surface or help a lawn recover after an icy winter. It would help if you also replenished nutrients by adding a nitrogen-rich fertiliser.  Chat to the friendly experts at your nearest GCA Garden Centre for the best products to use.

What to Prune

Maintenance is the heart of gardening, and September is an excellent time to get in there with some pinching, deadheading, and pruning.  Your flower garden will be healthier and lusher and will stay in bloom throughout the season. Most flowers benefit from having their spent flowers removed. This is called deadheading. Flowers that repeat-bloom will often do so only if the old, dying flowers are removed. If the dead flowers remain on the plant, they will go to seed, and the plant will stop producing flowers. 

Some plants have very crisp, thin stems and can be deadheaded using your fingers. This type of deadheading is called pinching. Some plants that can be pinched include daylilies, salvia, and coleus. Coleus are grown for their foliage, not their flowers. Pinching off the flowers encourages the plants to become bushier and fuller.

Rose Care
From the middle of September, you should pinch prune your Hybrid Tea roses. This encourages new basal growth, green leaves and root development. It spreads out the flowering cycle so that there is an almost continual supply of roses instead of one or two main flushes. Pinch –prune about a third of the shoots. Increase watering to at least twice a week and fertilise fortnightly.  

Watch out for aphids, thrips, bollworm and powdery mildew. To be effective, the spraying of roses for the control of pests and diseases needs to be carried out properly and with the correct understanding of both the pest and the applicable pesticides. One does get a canola oil, based pesticide combined with a systemic action fungicide which is a certified organic option. Visit your local GCA Garden Centre for advice on the best products to use to meet your needs.

Inland Gardening

(Gauteng, Free State, Northern Cape, North West, Mpumalanga and Limpopo)

With the rainy season upon us, ensure that your rainwater harvesting systems are set up and connected correctly.  Clean out your gutters to ensure proper water run-off and to make sure your collected rainwater is as clean as possible. 

Get your summer herb garden planted with these easy to grow summer herbs:

Thyme, rosemary, marjoram, oregano, basil, rocket, parsley and mint. Buy your seedlings from a Garden Centre GCA  renowned for quality plants and frequent deliveries of fresh stock. 

Get Weeding

Weed regularly before it gets out of hand. Treat weeds on paving, pathways and in gravelled areas with a non-selective herbicide. Visit a GCA Garden Centre for advice on the best products to use.

Plant your summer-flowering bulbs

 

Arum Lilies and Calla Lilies (Coloured Zantedeschia hybrids)- plant your Zantedeschia bulbs at the beginning of spring, around 4 - 5cm’s deep. Space bulbs 30 to 40 cm apart, because Zantedeschia has wide-reaching leaves and needs space. Choose a location that is in full sun but stays cool. Don’t plant in very dry soil.

Dahlias (Dahlia pinnata). 2019 is the Year of the Dahlia! These colourful, spiky, daisy-like flowers bloom from midsummer right through the first frost.  Select a planting site with full sun as they will blooms more with 6 to 8 hours of direct sunlight. They love the morning sunlight best. Choose a location with a bit of protection from the wind. Dahlias thrive in rich, well-drained slightly acidic soil. 

Coastal Gardening

(Western Cape, Eastern Cape, and KwaZulu-Natal)

September is a great time to refresh, top-up or replace pebbles and gravel around the garden - especially between paving stones where dust and mud have accumulated.

Check for algae and moss on paving. Scrub down with a solution of copper sulphate or use a moss killer.

Create a pretty spring border with the following indigenous flowering plants: Gazanias, Arctotis, Blue Felicias, Scabiosas and Cape daisies. 

Buy your seedlings from your local GCA Garden Centre. 

Get Pruning

Now is an excellent time to prune your Hibiscus, Poinsettia and other winter-flowering shrubs. Pruning your Hibiscus will help stimulate budding on new shoots. It also rejuvenates the plant after their long winter nap while encouraging them to maintain an attractive appearance and healthy, vigorous growth. The flowers of the Poinsettia have actually modified leaf structures called bracts. Once these have wilted and begun to die off, the Poinsettia requires a thorough pruning. Poinsettias may also require some trimming throughout the growing season to remain full and healthy.

 

Plant these Beauties to add some colour

Gerbera daisies (Gerbera jamesonii) are commonly grown for their bright and cheerful daisy-like flowers. They are indigenous to South Africa and come in various sizes and colours including pink, yellow, salmon, orange and white. Gerberas are best planted as seedlings, rather than seeds. This is because the flower resulting from seed may not reflect the colour expected and take far longer to flower. They prefer full sun with relatively sandy soils that are well-drained. None of the stems should be planted under the soil as it will rot, and the plant will die. Do not water them too often, as the soil should not become saturated. They can be grown in pots or containers too. They do well in the heat but do not handle the cold well.

Gladioli bulbs (Gladiolus species) come in a fantastic range of sizes, forms and colours, even lilacs and blues. It is a classic perennial known for its tall flower spikes. A great cutting flower, gladioli look beautiful in midsummer bouquets.  Plant Gladioli bulbs in the spring once the danger of frost has passed and the soil has warmed. Most Gladioli thrive in well-composted, well-drained loose, sandy to light loamy soils. A sunny position is best. The taller varieties, which should be staked, are often placed in the back of a garden to complement shorter plants nicely.
