Care Guide
Watering
Water regularly during nut development (late spring to early summer) to prevent nut drop
Fertilization
Apply balanced organic fertilizer once in early spring to support new growth. Refrain from fertilizing in late autumn to prevent tender new growth vulnerable to frost damage
Eggshell powder topdressing：Crush dried eggshells into fine powder; sprinkle 1–2 tablespoons around the base of the plant in early spring; lightly work into topsoil to avoid nutrient runoffPruning
- Prune in late winter to remove dead, damaged, or crossing branches and improve air circulation
- Thin overcrowded stems to allow light penetration to inner branches
- Cut back older wood to encourage new fruiting wood for increased nut production
- Remove suckers to maintain a tidy shrub or tree form
