The rain in late December has been a blessing for many gardeners in Eastern Australia but bushfires in Western Australian gardeners have been devastating. January can be a difficult month for gardening in some warm and temperate parts of Australia. Prolonged periods of heavy rain can cause seeds to rot before germination (or encourage fungal problems), and it is usually too hot for lettuce seeds to germinate in many parts of Australia. Keeping lettuce seed in a zip-lock bag in the fridge can “trick” seed into thinking conditions are cooler but only grow lettuce at this time of year if you can keep it well-watered or it will quickly bolt to seed.
During January and February, gardeners will have to adjust their planting to suit local climate conditions. If it is too hot to grow things in your area, use the time to do a good job of preparing beds for strawberries, leeks and winter vegetables.
The following planting guide is an abbreviated list for vegetables, fruit trees and some culinary herbs that can be planted in January in Australia and New Zealand. A comprehensive guide that includes planting times for the entire garden, as well as when to fertilise, prune, take cuttings or divide plants, can be found in my book Easy Organic Gardening and Moon Planting. If you are not sure which climate zone you live in, please see Climate Zones for more information.
