July gardening guide | Gauteng | Stodels Garden Centre


It may be the heart of winter, but that shouldn’t keep you out of the garden. July is a busy month of pruning roses, cutting back trees and sowing late plantings of your favourite winter veggies. Find more planting tips and ideas to attract feathery friends to your garden in this July gardening guide.

Spotlight on: Attracting wildlife to your garden
Having birds in the garden does not only help us manage pests naturally but also allows our bodies and minds to relax when we listen to their sounds. There’s a short supply of food during the winter months, so make an extra effort this season to attract birds and other wildlife with these tips:
  • Plant an indigenous aloe in your garden – its nectar attracts birds and insects beneficial to your garden.
  • Grow vygies and rock roses as a source of food and water for birds. Vygies also attract various insects with their small pollen deposits. Rock roses attract insects when their flowers are in bloom, which is beneficial to both your garden and birds. 
  • Make sheltered space in your garden for a bird feeder or birdbath. 

Plant & Sow
  • Ferns are not only trendy but have great air-purifying benefits too. Plant some easy-to-grow species in your garden or in pots, such as the dainty maidenhair, striking yellow sword fern, tough holly fern and evergreen leatherleaf fern varieties.
  • Plant colourful flowers in your garden, such as pansies, violas, snapdragons, calendula, primulas and gazanias. 
  • There’s still time to sow late plantings of green peas, lettuce, spinach, cabbage and carrots.
Prune & Trim   
  • July is a great time to remove any deadwood, leaves and diseased branches.
  • Pinch off faded flowers from winter-flowering annuals such as pansies, violas and poppies.
  • When pruning hydrangeas, remove all damaged, diseased or dead growth. Cut back the stems above thick, round, green buds.
  • Pruning roses encourages bigger, better blooms. Mid-July to mid-August is a good time to prune hybrid roses, tea roses and miniature roses. Water once a week now to allow them to rest. Seal cuts thicker than a pencil with Steriseal and spray with Lime Sulphur. 
  • Cut back trees that are getting too big. 
  • Feed winter-flowering annuals with foliar fertiliser, like Multifeed Flowergro, every two weeks.
  • Fruit trees and roses should be fed with slow-release fertiliser such as Atlantic Fertilisers Fruit & Flower. 
  • Feed cymbidium orchids every two weeks with Pokon for orchids. 
  • Citrus trees need to be fed with Wonder 3:1:5 slow-release fertiliser, then watered well. Dig fertiliser into the soil for best effect. Add mulch with acid compost to improve the soil’s pH levels.
  • Feed cool-season lawns like All Seasons Evergreen with 3:1:5 or Kirchhoffs Ludwig’s Vigorosa 5:1:5 fertiliser to give them a boost, particularly during extreme weather conditions. 
  • Treat aphids on vegetable plants such as cabbage and cauliflower with Kirchhoffs Ludwig’s Insect Spray +. 
  • Treat aphids on shrubs, roses and succulents with Efekto Malasol. Use the same pesticide to get rid of scale and mites on aloes. 
  • Use Efekto Funginex to treat black spots on aloes and roses. 
  • Use either Efekto Malasol or Efekto Oleum to get rid of scale on citrus trees. 
  Expert Tips   
  • To encourage continued flowering all through winter and into spring, plant stocks and Iceland poppies.
  • To keep your vegetable garden healthy and strong, continue to water deeply once a week.
