Eggshell powder topdress：Crush clean, fully dried eggshells into a fine powder; sprinkle 1–2 tablespoons around the base of the plant and gently work into the topsoil to avoid disturbing rootsPruning
- Remove dead, diseased, or crossing branches in late winter to improve airflow and sunlight penetration
- Thin overcrowded growth to encourage fruiting wood development
- Shape young container-grown trees to maintain a manageable size, cutting back overly long branches by one-third in spring
- Remove suckers growing from the rootstock to preserve the fruiting characteristics of the cultivar
