What to harvest in winter
Considered by some to be the queen of nuts, many macadamia varieties (such as Beaumont, Maroochy and GT 205) are harvested at this time of year. For some varieties like Beaumont that don't drop their fruit naturally, you'll need to cut the nut clusters off the tree. For those that do fall to the ground, placing a net under the tree helps make harvesting easier. Try to pick up your macadamias every second day so they don't become diseased or attract the local rats.
Mandarins, lemon and other citrus fruit ripen all through winter. With most citrus it's best to leave the fruit on the tree until you need it, but don't leave it too long as the birds might start to peck at the skins. Mandarins can also dry out if left on the tree for long periods after ripening.
When harvesting Brussels sprouts, remove the lower leaves first to make it easier to pick them and to allow the plant to direct energy into cropping. When the sprouts are firm and about 3-5cm in diameter, twist them until they break off at the stem, picking from the base upwards.
