Pests and diseases

  • Spray and feed all citrus and rose bushes after pruning with lime sulfur, to prevent scale on trunks and branches.
  • Keep watch for aphids on new growth and buds.
  • Slugs and snails are looking for tasty vegies, bulbs and flowering seedlings so protect them with snail pellets. If you have pets, use pet-friendly pellets (in accordance with product instructions).
  • Spray lawns for bindii.
  • Hungry caterpillars are on the hunt. Keep them away with Dipel or Success Ultra.

General garden care

  • Repot your indoor plants. Remove any brown or shrivelled fronds from indoor ferns.
  • Regularly water azaleas to extend blooming. Avoid wetting the flowers as this spreads petal blight.
  • Try not to over-water flowers as this will cause rot.
