The lingering warmth has everything growing like mad, and gardens are looking lush and green as ever. This is a busy month in the garden, with lots of gorgeous, colourful plants to add to your planting list, and a bunch of odd jobs to attend to before the crisp Autumn air starts to move in.

  • Now’s the time to plant container-grown azaleas, citrus, conifers, daphne and natives.
  • Fill your garden with spring-flowering bulbs like anemone, babiana, bluebell, Dutch iris, freesia, ixia, jonquil and ranunculus. Daffodil, grape hyacinth, hyacinth and tulip bulbs should be kept in the fridge for six weeks first.


  • Get your vegie garden in tiptop shape for a winter crop by adding lime or dolomite to the soil.
  • Fertilise annuals with weak fortnightly solutions of Nutrafeed or PowerFeed.
  • Avoid fertilising camellias and azaleas in April, as this will stimulate leaf growth at the expense of flower buds.


  • If you live in an area prone to cold and frost, stay away from secateurs this month. Plants will need leaf cover to protect them from frost.
  • Remove spent heads of pansies, violas and other annuals to encourage further flowering.


  • Protect newly-planted bulbs and seedlings with snail pellets. Use animal-friendly pellets like Multiguard Snail & Slug Killer and use as per packet instructions.
  • If mildew appears on your roses or hydrangeas, spray with fungicide.
  • Aphids on pansy and viola seedlings can be kept under control with pyrethrum.
  • Caterpillars munching on edibles can be controlled with Success ULTRA.

General garden care

  • Mulch autumn leaves and add them to the compost heap. If you leave them to compost in a heap by themselves, add Dinofert and dolomite to the pile to quicken the decomposition process.
  • Divide clumps of perennials such as iris, perennial phlox and Shasta daisies.
  • Repot plants into larger containers with fresh potting mix.
  • Prepare a bed for your roses. Dig the soil over in a sunny position, and then add compost or a rose planting mix.
  • Remove stone fruit from trees and dispose of them to eliminate sources of brown-rot fungus.
  • Start applying Seasol solution to help protect against frost in the colder months.
