  • Water the Illawarra plum tree deeply immediately after planting


Mulching a Illawarra Plum Tree

Mulching is an important activity to undertake when you have this tree. This is because it will help keep the tree’s roots cool and moist and prevent weeds from growing around the tree’s base.

You can use any organic material for mulching, such as bark chips, straw, or even newspaper. Ensure the mulch is not too thick, which can suffocate the tree. Apply a layer of mulch around the base of the Illawarra plum tree, and then water it well.


Fertilizing these trees is important to maintain their health and promote fruit production. Illawarra’s are light feeders, so you don’t need to use a lot of fertilizer.

A small amount of organic matter or compost added to the soil around the tree each year is sufficient. If you want to use a chemical fertilizer, choose one that is low in nitrogen and high in phosphorus. Apply fertilizer in early spring before new growth begins.


Pruning is best done in late winter or early spring. You can prune to shape the tree, remove diseased or damaged branches, or thin out the canopy to allow more light and air circulation. Illawarra plum trees are generally low-maintenance and don’t require a lot of pruning.


Watering is an essential part of tree care. The tree should be watered deeply and regularly, especially during hot weather. Mulching around the tree’s base will help conserve moisture and keep roots cool.


Soil is Illawarra’s best friend when growing this local Australian tree. It needs well-drained, sandy soil high in organic matter. If your soil is not naturally sandy, you can improve it by adding sand to the planting hole and mixing it with the native soil.

Improving your soil

To improve your soil, mix in some organic matter, such as compost or aged manure, before planting the tree. This will help the tree roots to establish themselves more efficiently and improve drainage. The ideal pH for these trees is between 6.0 and 7.0.

If your soil is too alkaline, you can lower the pH by adding sulphur to the ground. You can test the pH of your soil with a simple soil test kit.
