The following planting guide is an abbreviated list for vegetables, fruit trees and some culinary herbs that can be planted in May 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.
