The seasons have turned: It’s well and truly autumn and, with or without rain, cooler nights mean more soil moisture. The ground is still warm however, making April the best month to re-sow lawns. It’s the start of the planting season for trees and shrubs, while seedlings of lettuce and other greens are less likely to be fried to a crisp now things are cooler.
Compost fodder is abundant for soil building. Pile it into heaps, or lay directly onto beds to keep weeds away and rot down over winter.
left: Autumn is season of mists and mellow fruitfulness- and rotting. A great time to build compost heaps.
Leaves: Mow over them - the mix of grass clippings with chopped leaves is great compost fodder or mulch. Or rake them onto beds under trees or shrubs (avoid burying soft-stemmed, rot-prone shrubs like lavenders); compost them in separate heaps or black plastic bags for super-fine leaf mould, which takes up to two years but is great in home-made potting mix.
Weeds: Caught before they seed, fresh young weeds can be hoed or pulled and left on the soil surface as a light mulch, or added to the compost heap. Any weeds with seeds and/or fleshy roots should be kept away from the compost, unless you’re a super-hot compost baker. Instead, put them into heavy-duty plastic bags or cover with water in barrels, adding them to the compost once they form unrecognizable sludge.
Prunings: Clippings can be used directly as mulch around shrubs and trees. Perennials like cannas can be grown specially to harvest for compost fodder. Larger prunings can be chopped with secateurs or shears, or put through a shredder, to make weed-free mulch.
Plant: Brassicas, silver beet, lettuce and other salad greens, red onions, fennel, beetroot, strawberries.
Sow: Coriander, rocket, calendula, alyssum, miner’s lettuce, peas, broad beans, peas, green crops (direct); lettuce, spinach, silver beet, peas (in trays).
