Care Guide
Water deeply once or twice a week depending on heat and rainfall.
Apply a nitrogen-rich citrus fertilizer as new growth appears.. Citrus trees are heavy feeders; ensure adequate micronutrients like iron, zinc, and manganese.
Coffee Grounds and Eggshells：Mix used coffee grounds and thoroughly rinsed, crushed eggshells into the top layer of soil. This provides a gentle nitrogen boost and calcium. Avoid applying directly against the trunk to prevent rot.- Prune in late winter or early spring before new growth begins;
- Remove any suckers growing from below the graft union;
- Thin out crossing branches to improve airflow and light penetration into the canopy;
- Remove dead, diseased, or damaged wood promptly.
