Frost cloth is easy to use when the night temperatures fall. Have lengths ready cut to cover sensitive plants. Expect frost if the overnight temperature will be below 4 degrees and there is no wind.
Here's some top tips to help you protect your tender plants. Mild autumn weather encourages lots of fresh growth which can be damaged by frost. Protection is cheap and effective but needs to be planned for:
1. Completely drape the plant from the top all the way to the ground.
2. Apply the cloth just before sunset to make sure the heat produced in the ground during the day is captured.
3. Don’t leave any openings in the cloth for the warm air to escape or cold air to enter at night.
4. It is crucial that the frost cloth touches the ground, to the drip line of the plant.
5. Placing a heavy object like bricks or securing the fabric into the ground with weed mat staples will ensure that the cloth forms a seal with the ground and works well. The bricks or staples will also secure the cloth reducing the chances of it damaging the plant and blowing away should a wind arise.

Plant seedlings of cabbage, cauliflower, broccoli, silverbeet, onions and winter lettuce.
Potatoes will always be one of the best value vege crops. From a 1kg bag of seed, expect to harvest up to 20kg of delicious potatoes. Early seed potatoes can be sprouted in trays (chitting) in a light (not direct sun) cool place, allowing the sprouts to form. Remove all but 3 or 4 of the strongest sprouts when planting. Egg cartons make great chitting trays.

Trim back the untidy growth of lavender, canna lilies, fuchsias and geraniums.
Agapanthus and Arthropodiums (Reinga Lilies) develop a skirt of old leaves around the base of the plant. Pull these off to tidy the look of the plant and remove sites for snails, slugs and earwigs to hide.
Selectively prune back and thin out branches on trees and shrubs to allow more light and air to reach through. Pay particular attention to trees that overshadow the lawn where the winter shade may enhance the growth of moss. Where moss occurs, treat with sulphate of iron.
Trim early sasanqua camellias after flowering to keep tidy and bushy.
Mop head and lace cap Hydrangeas can be pruned now. Prune out any thin and spindly growth. Cut back shoots that have flowered to the fattest, biggest buds that are next to each other. These buds hold next seasons flowers. If they are too high, prune down to the next two fat buds. Strong shoots that haven’t flowered can be retained or pruned back to strong buds at the desired height.
Mature rose bushes may be covered with lichen or scale. Spray with lime sulphur to defoliate the bush and kill off both lichen and the scale insects.
