Care Guide
Water young trees weekly to maintain consistent soil moisture; established trees only need water during severe droughts
Apply slow-release balanced fertilizer once in early spring before new growth emerges. Use fertilizer with slightly higher nitrogen content to support foliage growth in young trees
Composted coffee grounds tea：Brew fully composted coffee grounds in water at a 1:30 ratio; strain solids before applying as a root drench to avoid pest attraction and odor- Remove dead, damaged, or crossing branches in late winter to early spring before new growth starts
- Thin crowded inner branches to improve air circulation and reduce disease risk
- Maintain the tree's natural rounded canopy shape; avoid heavy pruning that disrupts growth structure
