Complete Citrus Care Guide

Site Selection

At least 6 hours full sun, protected from wind. In cool/foggy climates, site near a south-facing wall or driveway for reflected heat.

Drainage

Essential. Heavy clay or compacted soil? Use raised beds or containers. Sandy soil? Dig in 4–6 in. compost to 1 ft. depth for water retention.

Mulch

Shallow roots benefit from 2–3 in. compost/organic mulch under canopy, kept away from trunk.

Fertilizer

Citrus on Flying Dragon rootstock are sensitive to alkaline soils (pH 7+). Regular feeding mitigates this. Use citrus-labeled fertilizer with N-P-K plus iron, manganese, zinc. Follow package rates. Chlorotic leaves (yellow with green veins)? Spray foliar chelated iron + micronutrients. Withhold fertilizer fall through mid-winter.

Watering

Drip irrigation is most reliable, especially for containers. Keep soil moist, not soggy. In-ground: water when top 5–6 in. dry. Containers: when top 1–2 in. dry. Always moisten entire root zone. Consistency prevents fruit splitting (especially navel oranges).

Frost Protection

Water well before predicted frost. Wrap tree with Christmas lights, then cover with frost blanket or floating row cover.

Pruning

Late spring/summer for shaping. Remove suckers below graft union (scar on lower trunk). In deserts, allow low, full canopy to shade fruit/trunks from sunburn.

Harvest

Most ripen late fall–winter. Exceptions: 'Valencia' orange (spring/summer), lemons/limes (year-round). Ripen on tree. Taste-test sweet fruits; pick tart fruits before they get puffy.

Pest Control

Aphids, scale, spider mites target stressed trees. Spray thoroughly (including crevices) with horticultural oil or insecticidal soap. Scale most vulnerable at crawler stage (mid-spring, mid-late summer).
