Trees require care that changes with the seasons — from deep watering in summer to pruning and root management in winter. Our guides provide clear, step-by-step instructions to help you:
- Plant and establish young trees correctly
- Water deeply without encouraging shallow roots
- Identify nutrient deficiencies and fertilise effectively
- Shape and prune for structure, flowers, or fruit yield
- Deal with pests, diseases, and bark or root issues
You’ll find care guides for a wide range of species — including productive trees like mango, avocado, and olive, as well as natives like bottlebrush, lilly pilly, and jacaranda. We also provide specific fertiliser schedules for different stages of growth using Complete Grow’s balanced nutrient formulas.
Whether you’re growing trees in the ground or in large containers, these care tips are written for Australian soil types, rainfall patterns, and climate zones — helping you grow resilient trees that thrive for decades.
How often should I water trees?
Newly planted trees need deep watering 2–3 times per week for the first few months to help roots establish. After the first year, most trees can be watered less frequently — once a week during dry weather or summer, and less in cooler months. Deep watering is key: soak the soil at the root zone rather than light, frequent sprinkling. Mature trees generally tolerate longer gaps between watering but still benefit from deep soaking during heatwaves or drought. Our individual tree guides include specific watering tips based on tree type, age, and Australian climate zones.
When should I prune my tree?
Pruning times vary depending on the type of tree and its growth habits. Most deciduous trees should be pruned in late winter or early spring before new growth begins. Evergreen and flowering trees may be pruned after flowering to avoid cutting off future blooms. Remove dead, diseased, or crossing branches any time of year to maintain structure and airflow. Over-pruning can stress trees or reduce fruit and flower yield, so it’s best to follow species-specific pruning advice. Our tree care guides provide detailed pruning timelines for each species, including citrus, native, and ornamental trees.
Why is my tree dropping leaves outside of autumn?
Unseasonal leaf drop is often a sign of stress — from overwatering, drought, poor drainage, pest infestation, or nutrient imbalance. For evergreen trees, sudden leaf loss usually indicates a root problem or environmental shock. In deciduous trees, early leaf drop may occur from heatwaves, fungal issues, or severe pruning. It’s important to check the soil moisture, inspect for pests like borers or scale, and evaluate your fertiliser schedule. Our guides help diagnose common causes of leaf drop based on the species and symptoms so you can take fast, effective action.
What is the best fertiliser for trees?
Trees benefit from slow, consistent feeding to support strong root systems, leaf development, and long-term growth. In early spring, a balanced NPK fertiliser like 20-20-20 helps kickstart new growth, while potassium-rich fertilisers in late summer strengthen branches and improve flowering or fruiting. Deep-rooted trees may also need calcium or magnesium to support structure and nutrient uptake. Our care guides include fertiliser recommendations tailored to each tree’s growth stage — whether you’re growing fruit trees, native ornamentals, or evergreens in pots or the ground.
