What to grow in September 2013

seedlings It is been a milder winter in many parts of Australia and this can be misleading because nights are still quite cold early this month and small seedlings may still need protection at night. It is also too cool to sow warmth-loving crops directly into garden beds in early September.
For gardeners in Temperate climate zones: if temperatures overall in your area has been warmer than usual, you may find the Warm climate planting guide more suitable from mid September, while areas experiencing colder than usual weather would be wise to follow the Cool climate guide until the overnight weather warms.
The following gardening advice of what to grow in September is an abbreviated list for vegetables, fruit trees and some culinary herbs that can be planted in August in Australia and New Zealand. A comprehensive monthly guide that includes planting times for the entire garden, as well as when to fertilise, prune, weed, take cuttings or divide plants, can be found in my book Easy Organic Gardening and Moon Planting 2006, 2009, 2012.

* For gardeners who do not use moon planting: sow or plant out any of the following list at any time this month, although you may find germination rates are lower when the Moon is in Last Quarter phase..

If you haven’t done so, check citrus trees (especially grapefruit and lemons) this week and prune off any galls before adult wasps emerge to lay eggs in new shoots. Burn prunings or dispose of them in a sealed plastic bag.
