Care Guide

Fertilization
Apply a nitrogen-rich citrus fertilizer as new growth appears.. Citrus trees are heavy feeders and require regular micronutrients like iron and zinc.
Coffee Grounds and Eggshells：Mix used coffee grounds and finely crushed eggshells into the topsoil. Coffee grounds provide gentle nitrogen and slight acidity, while eggshells offer calcium. Avoid applying too thickly to prevent mold.Pruning
- Prune in late winter or early spring before the main flush of new growth;
- Remove any dead, diseased, or crossing branches to improve air circulation;
- Pinch back vigorous shoots to encourage a bushier, more compact shape;
- Remove any suckers growing from below the graft union immediately.
