Care Tips

Water

Fertilizing

• Timing: Apply balanced fertilizer (10-10-10) in early spring.
• Amount: Follow package instructions based on the tree’s size and age.
• Cautions: Avoid excessive nitrogen, which can lead to more foliage growth rather than fruit production.

Pruning

• Timing: Prune annually in late winter or early spring before new growth begins.
• Purpose: Shape the tree, remove dead or diseased branches, and improve air circulation.
• Technique: Maintain an open center to enhance light penetration and reduce disease risk.

Pest Management
