Establishment (Year 1)
12 monthsYoung tree focuses on root development and framework growth. Trunk thickens and primary branches establish.
Water regularly but do not fertilize heavily. Remove flower buds to encourage vegetative growth. Stake for wind protection. Apply mulch.
Development (Years 2-3)
24 monthsTree grows substantially in height and width, developing secondary and tertiary branch structure. Canopy fills in.
Begin light fertilization in spring. Prune to shape canopy. Continue removing early flower buds to build tree structure. Maintain consistent watering.
Pre-Production (Years 4-5)
24 monthsTree reaches near-mature size and begins producing small numbers of flowers and fruit. Canopy is well-established.
Apply balanced citrus fertilizer. Allow some fruit to develop. Thin excessive fruit to ensure quality. Continue structural pruning as needed.
Production (Year 6+)
Ongoing annuallyTree consistently produces abundant fruit. Mature tree reaches 15-20 feet in height and width. Annual flowering and fruiting cycles establish.
Apply regular fertilizer (3-4 times annually). Thin fruit for optimal size. Prune lightly to maintain shape and airflow. Monitor for pests and diseases.
Harvest
November-March (varies by location)Fruits ripen to golden-orange color over several months. Fruits become sweeter and juicier as they mature on tree.
Harvest when fully colored; fruits will not continue ripening after picking. Use pruning shears to avoid damaging tree. Handle carefully to prevent skin damage.

Harvest Tips
Fruits typically ripen November through March, depending on location. Harvest when skin is fully golden-orange and fruits yield slightly to gentle pressure. Use pruning shears or bypass loppers to cut fruit from stem; do not pull or twist. Fruits do not continue ripening after harvest. Peak sweetness and juice content occur when left on tree as long as possible before hard freezes. Can store 2-4 weeks in cool conditions.
