How to Grow Apple

Growing guide

Overview

Apple trees are long-lived, productive fruit trees grown for fresh eating, cooking, and storage. They thrive in full sun and well-drained loamy soil, and with proper pruning and pollination they can bear fruit for decades. They are hardy in USDA zones 3a–8b and require moderate water.

Soil & planting prep

Choose a site with well-drained loamy soil and a pH between 6.0 and 7.0. Improve heavy clay or sandy soil by mixing in compost. Space standard trees 15–20 feet apart and dwarf trees 8–10 feet apart, planting at the same depth they grew in the nursery.

When to plant

Plant bare-root apple trees in early spring, about 4–6 weeks before your last frost date, while they are still dormant. Container-grown trees can be planted anytime from early spring through early fall, but avoid planting during extreme heat or drought. In zones with mild winters, fall planting is also acceptable.

How to plant

1. Dig a hole twice as wide as the root ball and just as deep, so the graft union sits 2–3 inches above the soil line.
2. Soak bare-root trees in water for 1–2 hours before planting; for container trees, water the root ball thoroughly.
3. Backfill with native soil, firming gently to remove air pockets, and water deeply.
4. Apply a 2–3 inch layer of mulch around the tree, keeping it a few inches away from the trunk.
5. Water regularly during the first growing season and stake the tree if it is in a windy site.

5 common mistakes to avoid

• Planting a single variety without checking pollination needs: most apples require a compatible second variety nearby to set fruit, so always plant two that bloom at the same time or choose a self-fertile type.
• Burying the graft union: if the swollen graft joint is covered with soil, the scion can root and the tree may sucker or die, so keep it 2–3 inches above the soil surface.
• Pruning at the wrong time: heavy pruning in summer or fall encourages tender growth that winter-kills; prune only in late winter while the tree is dormant.
• Overfertilizing with nitrogen: too much nitrogen produces lush leaves but few flowers and fruit, and can burn roots; test your soil and fertilize only if growth is weak.
• Letting the tree bear fruit too early: allowing a young tree to fruit heavily in its first years stunts its structure; remove flowers or small fruits for the first two seasons.

Harvesting & storage

Pick apples when the background color turns from green to yellow or red, the fruit separates easily from the spur with a gentle twist, and the seeds inside are dark brown. Harvest by cupping the fruit and rolling it upward, rather than pulling straight down. Store in a cool, humid place (32–40°F) for up to several months, depending on variety.

Companion planting

Good companions include chives, garlic, and nasturtium, which may help repel pests. Avoid planting potatoes and grasses near apple trees, as they can compete for nutrients and harbor pests.

Growing in containers

Apple trees are not well-suited to containers; they have large root systems and need the space of in-ground planting to thrive. For patio growing, choose a genetic dwarf variety in a 20-gallon or larger pot, but expect limited fruit and more frequent watering.

Pro tips

Plant at least two compatible varieties for cross-pollination (or a self-fertile variety). Choose disease-resistant varieties for lower maintenance. Prune every winter to maintain shape and production.
