Golden Treat™ grows outdoors in USDA zones 4–9. Its slim, columnar shape (about 10 ft. tall and 2 ft. wide at maturity) makes it equally at home planted in the ground or grown in a large container on a sunny patio or balcony.
Planting
- Choose a site in full sun — at least six hours of direct light a day for the best fruit set and flavor.
- Plant in well-draining soil. If drainage is poor, amend the bed or use a roomy container with drainage holes.
- Dig a hole about twice as wide as the root ball but no deeper than the roots themselves.
- Set the tree so the graft union (the swollen bend low on the trunk) stays a couple of inches above the soil line; never bury it.
- Backfill, firm gently, and water in well. Mulch the root zone to hold moisture, keeping the mulch a few inches back from the trunk.
Care & maintenance
- Water. Keep the soil evenly moist the first season while the tree establishes. Container trees dry out faster — check often in summer and water when the top inch is dry.
- Feed. Apply a balanced fruit-tree fertilizer in early spring as growth begins. Avoid heavy late-season feeding, which pushes soft growth that won't harden before winter.
- Light & temperature. Full sun is essential. Hardy in zones 4–9; in containers in the coldest zones, shelter the pot against a wall or move it to an unheated garage during hard freezes to protect the roots.
- Prune. Columnar apples need very little pruning. Trim any wayward side shoots in late winter to keep the tight upright form, and remove dead or crossing wood.
- Pollinate. Most apples fruit best with a compatible second apple variety blooming nearby for cross-pollination. Plant another apple that flowers in the same spring window — or count on a neighbor's tree or a crabapple — for the heaviest crop.
- Pests & disease. Watch for codling moth, aphids, and apple scab. Keep fallen leaves and fruit cleaned up, ensure good air movement, and treat early if problems appear.
- Harvest. Apples ripen for picking around September. They're ready when the gold color is full and the fruit twists free from the spur with a gentle lift.
