• Prune dead or diseased branches to maintain tree health and shape.
• Monitor for gall formation, as these can be harvested for medicinal use.

Propagation Methods

Seeds: Collect fresh seeds from mature fruits. Scarify seeds (e.g., by soaking in hot water for 24 hours or light sandpaper abrasion) to break dormancy, then sow in well-drained nursery beds or polybags during monsoon season (June-July). Germination rates can be variable. Cuttings: Hardwood cuttings taken from mature branches can be used, treated with rooting hormone, and planted in sandy media, though success rates are generally lower than seed propagation. Air Layering: This method can be successful, especially during the monsoon, by wounding a branch, applying rooting hormone, and covering with moist medium.

Common Problems

Common pests include sap-sucking insects like aphids and scale insects, which can be managed with neem oil sprays or insecticidal soap. Fungal diseases such as leaf spot or powdery mildew can occur during high humidity; these can be addressed with Bordeaux mixture or organic fungicides. Nutrient deficiencies are rare in its native habitat but can manifest as yellowing leaves (nitrogen deficiency) or stunted growth, which can be corrected by amending soil with compost or balanced organic fertilizers. Overwatering in poorly drained soil can lead to root rot.
