🗓️ When to plant

Plant in early spring after the last frost, or in autumn in warm climates where winters are mild. Container trees can be planted anytime frost-free conditions allow.

🌰 How to plant

Dig a hole twice as wide as the root ball and just as deep, in a sunny, wind-protected spot.
Place the tree so the graft union (if present) sits 5–10 cm (2–4 in) above soil level.
Backfill with amended soil, gently firm, and water thoroughly until water settles.
Mulch around the base with 5–8 cm (2–3 in) of organic mulch, keeping it away from the trunk.

💧 Care

Prune lightly after harvest or in early spring to maintain shape and remove dead or crossing branches.
Fertilize every 4–6 weeks during the growing season with a balanced citrus fertilizer or one higher in potassium.
Monitor for pests year-round and inspect leaves regularly for signs of stress or disease.
Protect young trees from strong winds and provide afternoon shade in extremely hot climates.
In cold regions, cover trees or move containers indoors when temperatures drop near freezing.

🧺 Harvest

Pick oranges when fully colored and slightly soft to the touch; they don't ripen further after picking, so wait until mature. Harvest by gently twisting or using pruning shears to avoid damaging the tree.

🐛 Common problems

Scale insects: Spray with horticultural oil in early spring or use insecticidal soap for mild infestations.

Citrus leaf miner: Remove affected leaves and spray with neem oil or insecticide during peak activity periods.

Root rot: Improve drainage immediately, reduce watering frequency, and consider repotting into fresh, well-draining soil.

Citrus canker: Prune and destroy infected branches, avoid wetting foliage, and apply copper fungicide if available in your region.
