Hey kids! It’s time to make a sundial!

Posted on: October 20th, 2020 by Shahnee Stockigt No Comments

This November, Life is a Garden is helping the whole family get into the spring of things by celebrating our South African sunshine. Here’s an educational, hands-on project all about time, the Earth’s rotation, and our life-supporting sun. Get ready scientists and explorers, time is upon us!

A bit about the sundial

Did you know? The sundial is the oldest known instrument for telling time! This ancient, mysterious doohickey tracks the position of the sun using a gnomon, which is the centrepiece of the sundial that indicates time by the position of its shadow. Up until the early 19th century, sundials were the main instrument people used to tell time. When correctly positioned, sundials can even tell time down to the minute!

 

You will need:

  1. A flat piece of wood: This is going to serve as the body of the clock. You can upcycle an old slab of wood from the garage or the scrapyard, use a tree stump, or even repurpose a tile slab. Your local GCA Garden Centre has as lovely variety of wooden décor slabs to choose from.
  2. Pebbles or stones: These are going to be the hour placeholders. They can be collected during a walk, scavenged from the garden, or purchased from your favourite GCA Garden Centre. We recommend using pebbles with a flatter surface and ones lighter in colour.

Sunny Suggestion: Instead of using pebbles as hour placeholders, you could also use little succulent or cactus pots! Your garden centre has THE cutest variety of mini cactus pots and this DIY is the perfect opportunity to home a couple. If you’re going for the potted look, you could use the underside of a pot as your clock base too!

3. Paint: To paint numbers of the clock onto each stone and decorate as desired.

4. A dell stick for the gnomon: This is the centrepiece of the sundial that when the sun hits it, a shadow is cast onto the wooden clock base indicating time.

5. A compass or Aunty Google: You will need to find true North to accurately position your sundial.

6. Some super glue, a sunny spot in the garden, and an analogue watch.

 

Positioning and assembling your sundial
  • True North, here we come! Did you know? There is even a sundial app for kids to download! They can ask Aunty Google or the App Store for help. If you still have a compass, then get your little explorer out there to pinpoint exactly where Santa comes from.
  • Once you have found true North and are happy with your sunny spot in the garden, position your wooden clock base. Kids can add all sorts of personal touches to their clock base with some paint or even by burning some cool patterns into the wood using a magnifying glass.
  • Paint on the numbers of the clock onto each pebble or stone. Have some fun with different numbering styles. Kids could even go for an ancient civilisation look and paint in Roman Numerals or hieroglyphics.
  • Use the super glue to secure your dell stick in the centre of the clock base. You can also use a pencil or straight stick from the garden.
  • Position your hour place holder pebbles around or on top of your clock base, depending on how large your stones are.
  • By now, kids should see the shadow being cast onto the sundial. Use your analogue watch to see if the shadow and real-time are matching up. If not, make sure the kids really did find Santa’s true home, and perhaps help them to do a little repositioning.

A DIY garden sundial is an excellent opportunity to get kids outdoors, inspire a thirst for exploration, create awareness for the vastness of our universe, and teach a thing or two about the evolution of time and life on Earth.

October in the Garden Celebrating Gardening

Posted on: October 1st, 2019 by Shahnee Stockigt No Comments

With the 20th of October being ‘Garden Day’ and October being ‘Rose month’ – what an opportune month to celebrate gardening!

Rose month

Your roses should be producing their first flush of perfect blooms and the sun is still not too scorching – allowing the blooms to last longer. Spring is also the ideal time to select and plant new rose bushes in your garden. These are some of our favourites:

  • Ingrid Bergman POULman unfading red
  • Memoire KORfuri   unspoilt white, fragrant
  • Zulu Royal DORient mauve, fragrant
  • King David TANmarsal bronze
  • South Africa KORberbeni golden

Pop in to your nearest GCA Garden Centre for more inspiration and supplies.

 

What to Sow

As soon as the soil warms up in mid spring, you can start to sow all your summer veggies, including beans, sweetcorn and tomatoes. Two of your main “must haves” for your summer salads are cucumber and celery.

  • Cucumber seeds should be sown in composed enriched soil in a sunny site. When flowers start forming, feed with potassium-rich organic fertiliser. Support plants well so they can climb upwards, even when the cucumbers get large. This also protects the cucumbers from slugs. Harvest /cut the cucumbers off the plant when they are still quite young, avoiding the skin becoming hard. Regular harvesting encourages a more continuous production of
  • Celery needs rich, moisture-retentive soil which is achieved by digging in plenty of compost. Sow in shade or semi-shade. Feed weekly liquid feed in mid to late summer. Plants should be spaced 20cm apart and kept moist. You can cut stems frequently as required.
What to Plant

Amaryllis (Hippeastrum) - one of the easiest and most rewarding bulbs to grow, amaryllis produce showy, trumpet-shaped blooms that add a flamboyant touch to your garden or home. Often referred to as the Christmas flower because they typically bloom around five weeks after being planted (during the warmer months). For this reason, amaryllis make a wonderful gift at Christmas time and can also make gorgeous centre-pieces for the Christmas dinner table.

Amaryllis do well in most soil types, provided they get sufficient drainage. Plant in a sunny or semi-shade position and for the best results, give your amaryllis some bulb food every two weeks. These beauties are perfect for pots, and can be planted in groups in your garden.

As they retreat into dormancy at the end of the warmer months, you can decrease watering and leave them in the soil throughout the various seasons. Do not stop water them until all of their foliage has receded.

Star Flower or Egyptian star cluster (Pentas lanceolata) - a fast-growing, small to medium-sized herbaceous shrub with light green foliage. Pentas comes in a variety of colours, including pink, red, mauve and white. The beautiful flowers attract butterflies and hummingbirds and make great cut flowers. The shrub grows quickly in full sun or semi-shade and vary in height but the modern hybrids are lovely compact bushes, growing +-100cm tall and +-30cm wide.  Plant them into rich, well-drained soil. Cut off the dead flowers regularly to encourage re-flowering or continuous blooms.

What to Spray

There are many types of broadleaf weeds that can get their roots into your lawn. Clear out and control weeds in lawns, by using a selective broadleaf weed killer that is safe for use on established lawns.

  • Aphids are rife on new growth, they feed on the sap of most garden plants and are usually found in large colonies on the new growth tips, flower buds or on succulent foliage. They are particularly prevalent during early spring and into the summer season, sucking the sap from plants and causing malformed flowers and foliage. They can be controlled with one of the numerous different insecticides registered for use on these pests.

Chat to a specialist at your nearest GCA Garden Centre for advice on the various products available and what would work best for your needs.

What to pick

Growing your own veggie garden is both fun and rewarding. Ready for harvest in October are: asparagus, broad beans, broccoli, cabbages, cauliflower, lettuces, rocket, spinach (Swiss chard) and spring onions. The perfect ingredients for some very tasty and creative summer salads and veggie dishes. If you don’t have your own edible garden established yet – it is never too late to start.

Rose Care

It’s not hard to see why October is “Rose month” as you enjoy your roses in all their glory.

Water deeply at least once a week - for roses to flourish it’s best to water them twice weekly giving them 15mm of water each time.  Roses that were fertilised in mid-September should be fertilised again in mid-October or early in October if September was skipped. This encourages root activity and new leaves and flowering stems to sprout. Only use the recommended amount of granular rose fertiliser.

To prevent aphids, bollworm, thrips, powdery mildew and black spot, spray fortnightly with the correct organic spray.

For quality blooms, disbud hybrid teas by removing side buds out of the leaf axles beneath the terminal bud. Remove spent blooms; not only will your rose bed look tidier; this also encourages the production of new quality stems. If you’d like long stemmed blooms for the house, don’t cut more than half of them on a bush.

Visit your local GCA for advice on the best products to use to meet your needs.

Garden Day

On Sunday, 20 October 2019 we will celebrate Garden Day. Instead of working in your gardens – this is a day to put down your garden tools, invite family and friends around, relax and celebrate your garden with them. Flower crowns are a beautiful way to celebrate your garden.  Making and wearing the fun and colourful accessory is a great way to show off your garden blooms. Pick a few flowers from the garden and make your own flower crown.

Inland Gardening

  • Before you know it, December will be here – start preparing your garden now for all your holiday and festive season needs.
  • Clean out water fountains and ponds and ensure you unclog the impeller on your water feature pumps.
  • Check that your irrigation system is working effectively. Unclog nozzles and filterers, and replace any pipes or heads that need replacing. You don’t want to be rushing around last minute before you go away in December to ensure your watering system is working!
  • Plant additional veggies (like beans, sweetcorn, tomatoes, celery and cucumber) so that you have a good selection and enough to feed your family and any visitors over December. Sow more parsley, chives, basil and coriander seeds in your herb garden.
  • Look out for insects such as aphids, mealy bugs and whitefly on soft new growth and control with the correct insecticide.
  • Tidy up garden containers by pruning shrubs and specimen plants to maintain a round shape. Plant some bright red bedding begonias around the stems and these will give you a great splash of festive colour in December
Coastal Gardening

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

  • Snails and slugs are more than likely sneaking out of their hiding places at night and eating seedlings and young shoots in your gardens. There are a number of ways, including traps to keep these guys from destroying your plants. Chat to the experts at your local GCA Garden Centre to find a solution that best meets your needs.
  • Inspect all members of the lily family such as agapanthus, crinum, clivia, nerine, amaryllis and haemanthus for lily borer. They are most active at night and can be treated with insecticides.
  • Clean up container plants and top dress with mulch, crushed peach or apricot pips or pebbles to keep the soil moist between watering.
  • Plant tropical fruits such as lychees, mangos and bananas.
