While many of the recommended trees are drought-tolerant, regular watering is crucial during the establishment phase. Mulching around the base of the trees can help retain moisture and regulate soil temperature.
Protection from Heat
During Melbourne’s hot summers, young trees may require protection from extreme heat. Consider using shade cloth or planting shade-tolerant species in areas that receive intense afternoon sun.

Young Trees: Newly planted trees need regular watering to establish their roots. Water them deeply once or twice a week, depending on the weather and soil conditions.
Mature Trees: Established trees usually require less frequent watering. During dry spells, deep watering once a month may be sufficient.
Proper Watering Techniques
Deep Watering: Ensure water penetrates deeply into the soil, encouraging deep root growth.
Mulching: Apply mulch around the base of the tree to retain moisture and regulate soil temperature.
Avoid Overwatering: Too much water can lead to root rot and other problems.
3. When and How Should I Prune My Trees?
Best Time to Prune
Dormant Season: Late winter or early spring, before new growth begins, is generally the best time to prune most trees.
Exceptions: Flowering trees should be pruned after they bloom, and some species, like oaks, are best pruned in late fall or early winter to prevent disease.
Pruning Techniques
Dead and Diseased Branches: Remove any dead, damaged, or diseased branches first.
Thinning: Reduce density to improve air circulation and light penetration.
Crown Raising: Remove lower branches to lift the canopy.
Avoid Topping: Never top a tree, as it can lead to weak, unhealthy growth.
