October Vegetable and Herb Gardening Calendar for Subtropical Climate Australia

October is the mid-spring period, where flowers bloom in abundance, and the warmer weather with rain bringing ideal conditions for lush plant growth.

In the northern regions there are more hot sunny days, with rain increasing and thunderstorms.
Sydney is quite rainy this month, averaging 11-12 days of rain and may also be windy.

Things to Do This Month:

• Plant evergreen shrubs and trees (including citrus trees).
• Relocate evergreen shrubs, as they’re able to regrow their roots during the mild weather.
• Set up windbreaks (e.g. plastic tree guards) to protect newly planted evergreen trees and shrubs.
• Plant potted deciduous fruit trees and vines, since they are in leaf and have growing roots, they can be planted anytime, but the best time is in spring & autumn when weather is mild.
• Relocate any self-seeded annuals to better locations in the garden.
• Tidy up overgrown plants and tie growing vines back to supports or wires.
• Continue propagating plants by taking cuttings or layering (ground layering and air layering).
• Feed brambleberries (raspberries, blackberries & hybrids).
• Last chance to remove dead winter growth, and to dig up and divide perennial plants
• Clean out ponds and water gardens, divide waterlilies, plant new aquatic plants.
