Description
Granny Smith Apple trees produce delicious, slightly tart fruits that store well after picking. They start flowering around early October and are ready to harvest towards the end of March.
The Granny Smith Apple is a medium to low-chill variety, temperatures below 7 degrees in winter are required.
Apple trees are not self-fertile, requiring a second variety to cross-pollinate to bear fruit. The Golden Delicious variety is the perfect cross-pollinator.
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 good potting soil and compost mix, leaving 10-15cm of roots.
Mulch
Apply a good layer of mulch of about 7-8 centimetres around the base of the tree. This will help keep the soil moist.
Watering
Ensure not to overwater your tree, especially if 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.
Fertilizing
Fertilise using a nitrogen fertiliser and good compost. For young trees use our slow-release nitrogen-rich Berry/All-plant fertiliser. Apply 1 teaspoon every 4-5 months.
Superfrass is a natural high quality organic growth enhancer and pesticide. Packed with macro-elements (N, P, K) and micro-nutrients (Zn, Cu, etc.), which enable your plants to grow robustly.
Pruning
This is usually done during winter when the tree is dormant. Prune the same as you would do a full-size fruit tree, removing damaged or diseased branches and ones that grow to the centre of the tree.
Staking
Dwarf trees use rootstock with a very small root system as they will need support, especially during fruiting. Tying them to a stake in order to secure the rootstock is deemed necessary.
Pollination
Self-fertile but will perform better with a different variety. Cross pollinate with any other variety.
