Care Guide
Keep soil consistently moist but not waterlogged; increase frequency during hot, dry spells

Eggshell and banana peel compost tea：Steep fully composted eggshells and banana peels in water for 3 days; dilute 1:20 before applying as a root drench to avoid nutrient burn and odor- Prune dead, diseased, or crossing branches in early spring to improve airflow and sunlight penetration
- Thin crowded shoots to encourage bushier growth and better fruit development
- Trim back overgrown branches to maintain a compact shape, especially for container-grown plants
- Remove suckers growing from the base to direct energy to the main tree trunk
