Gardeners' Diary - August 2015

Feed orchids weekly with high-potassium, full strength fertilizer from August to December and then a high-nitrogen fertiliser for the rest of the year.

Clear gutters and downpipes of leaves and clear firebreaks.

Check that hoses and sprinklers are in good working order—bushfire season is just around the corner!

Regularly check flowers and the last of the winter vegetables for watering and complete mulching before the really windy weather comes upon us in September. Some folk wait until the first really good rain before fertilizing and mulching.

Continue to feed flowers and vegetables fortnightly using either liquid seaweed or a liquid flower and fruit fertilizer.

Control leafminer and over-wintering bronze-orange (stink) bug on citrus by spraying leaves, branches and trunk with white oil.

Assiduously remove fallen leaves from frangipani and dispose of in the
garbage to control frangipani rust disease.

Prune hibiscus and feed with poultry manure, mulch, then water well. Pruning at this time allows new growth to harden before harmful erinose mite eggs hatch and start to ravage the bush.

Prune, feed, mulch and then water camellias once flowering finishes as a thank you for their bountiful blooms.

Complete planting bare-rooted deciduous trees, shrubs and vines before the end of the month.

Plant Asparagus Pea, Beans, Beetroot, Capsicum, Chilli, Chinese
Cabbage (Wong bok), Chives, Cucumber, Daikon, Kohlrabi, Mint, Warrigal Greens, Silverbeet, Spring Onions, Summer squash, Tomatillo, Tomato and Zucchini. All these vegetables should be ready to pick in November.

Abelia and Buddleia—remove old canes from the base and reduce the whole shrub by one-quarter to a half, shorten overlong canes.

Water lilies—overcrowded pots should be divided and replanted in aged cow manure into which a few grains of Osmocote Plus may be embedded.  Wash the roots of the plant in a bucket of water before dividing and separate with a sharp, disinfected knife. Cover the surface with gravel. A good idea at this stage is to ‘grow on’ these divided plants in a 10 ltr bucket of water for about a month. A weight is placed on top of the plant to ensure that the plants do not spring out of their pots when lowered into the bucket. If re-potting is not
required, clean out the pond.
