Australian natives, camellias and other early spring-flowering evergreens should be planted as soon as possible. This will allow them to establish a strong, vigorous root system well before summer. Beware of root-bound plants, they often struggle to survive. If you are interested in growing native plants, make a note to visit the Australian Plant Society’s Spring Sale and Show at the Wayville showgrounds next weekend. Ants have come out of hiding and are searching for food. They delight in spreading insects such as scale and aphids from one plant to another. Find their nest and apply one of the many insecticides prepared specifically for ant nest control. These sun-loving plants will provide a blaze of colour during late summer and autumn if planted during late October, November or early December. Meanwhile, dig the ground; add plenty of organic material and half a cup of complete fertiliser to each square metre of garden. A regular light application of a complete fertiliser will produce better blooms than a single large application early in the season. Wattles and other winterflowering Australian native shrubs that have finished flowering should be pruned lightly to stimulate new growth and maintain a compact shape. Cymbidium orchids should be re-potted as soon as flowering spikes have died down. If the plants did not flower, they should be re-potted or divided in the next few weeks. Use a chunky bark for repotting. As soon as spring-flowering deciduous trees have finished blooming, they should be trimmed lightly to encourage new growth and increase the flowering potential for next season. Many couch and kikuyu lawns have large populations of broad leafed weeds growing in them. These should be controlled by spraying with a weedicide containing MCPA and Dicamba.
