Position
For extra winter chilling, apple trees should be planted in full sun, with 6 to 8 hours of sunshine, preferably on the south side of the property. If growing your tree in containers, consider moving it outdoors during winter. Use at least a 50L container if not planting directly into the soil.
Size
Granny Smith Apple trees can grow to 12m in height. Plant about 5-8 metres away from any structures.
Soil type
This tree will grow well in well-drained soil with a pH of 5.8 to 7. The soil needs to be fertile and moisture-retentive. Use a good potting soil and compost mix.
Watering
Ensure you do not overwater your tree, especially if it is grown in a container. Watering once or twice a week will be completely sufficient. You might water more during the summer when fruit is on the tree, especially during prolonged dry periods.
Mulching
Add a thick layer of pine bark mulch, keeping it about 20 to 30 centimetres away from the tree trunk (any closer may cause excess moisture and damage the trunk). This will retain soil moisture and prevent weeds from taking over.
Fertilising
Fertilise using a nitrogen fertiliser and good compost. Use our slow-release nitrogen-rich all-plant fertiliser. Apply 1 teaspoon every 4-5 months.

Pests and Diseases
Apple trees are prone to Powdery Mildew. Spraying regularly with Agricultural Neem Oil or Effective Microorganisms (EM) Control will assist with prevention or post-treatment. If you already have aphids, mites, or mildew, wash the tree with a strong stream of water. When dry, spray with Neem oil or EM Control. Consistency is key.
Pruning
This is usually done during winter when the tree is dormant. Prune the same as you would a full-size fruit tree, removing damaged or diseased branches and those that grow to the centre of the tree.
Pollination
Self-fertile but will perform better with a different variety. Cross-pollinate with any other variety.
