Fertilization
Apply diluted balanced slow-release fertilizer once monthly. Cease fertilization in autumn and winter when growth slows
Eggshell powder topdressing：Crush thoroughly dried eggshells into fine powder; sprinkle 1–2 tbsp around the base of the tree; gently work into topsoil to boost soil calcium levels and reduce blossom end rot riskPruning
- Remove dead, damaged, or crossing branches in late winter before new growth emerges
- Thin crowded inner branches to improve air circulation and light penetration
- Shape young trees to establish a strong central leader and desired form
- Avoid heavy pruning of mature trees to prevent stress and dieback
