Gauteng August 2018 Gardening Guide

August 2018

We might not be quite done with winter yet, but signs of spring are all around us. From lighter, early mornings to promising buds, signs of new beginnings abound. Now is the month to plan your spring gardening tasks, prepare your tools for some hard work and get ready for a busy season ahead.


Plant & Sow
  • Sow the seeds for edible varieties such as nasturtiums, Italian parsley, spinach, Swiss chard, lettuce, rocket, carrots, beetroot, radish, beans, sweet peppers, tomatoes and celery.
  • Plant spring-flowering seedlings such as begonias, primulas, calendulas, poppies, snapdragons, and stocks.
  • Summer-flowering pansies and violas will be in full-colour display at Stodels Garden Centre. Pick your favourite colour to plant now for flowers until late summer.
  • Cold-loving alyssum will flourish in spring, so sow these seeds in any bare spots in the garden now.
  • Lavender of all types should be planted now for vivid pink-purple colour in summer.
  • Plant summer-flowering bulbs and rhizomes such as cannas, dahlias, gladiolus, golden arum, nerines, spider lilies, tigridia, and watsonias.
  • Fertilise clematis and fuchsias once every two weeks with Seagro, Nitrosol or MultiFeed. Pinch out the growing tips to encourage bushier growth and more flowers in summer.
  • Ensure deep pink- or blue-hued hydrangeas by feeding them with 25g of aluminium sulphate once every two weeks.
  • Feed winter-flowering bulbs, such as daffodils, with bulb food to supply nutrients for next year’s blooms. Don’t remove the yellowing foliage as this also helps to feed the bulbs.
  • Azaleas are beginning to bud, so ensure you are feeding them with Wonder Colourburst to ensure a healthy, full blooming season.
  • August is the month for lawn care, so revive yours with a spring treatment:
    • Rake your lawn and remove any winter debris and mow short and low
    • Spike for aeration.
    • Feed with a generous lawn dressing, such as slow-releasing Wonder 3:2:1, sustained-release Wonder 7:1:3 or organic, waterwise varieties such as Atlantic Lawn
    • In the case of All Seasons Evergreen lawn, a lawn dressing is not recommended. Rather trim lawn as normal and feed with Talborne Organic 5:1:5.

Bring the birds and the bees
Attracting birds into your garden helps you manage garden pests naturally, and bees and butterflies are crucial to encourage vivid spring colour. Buy a bird feeder and fill the bird bath with fresh water to welcome their return, and encourage butterflies and bees to the garden with a selection of flowering fynbos plants such as pincushion, buchu, wax flower and Erica varieties.
