Care essentials

Light

Plant in full sun — at least 6–8 hours of direct sunlight daily is required for vigorous growth and fruit production. Calamondin is well-suited to NE Florida's zone 9b and is one of the most cold-hardy citrus options for the region.

Water

Fairly drought tolerant once established; water deeply but infrequently and allow the soil to partially dry between waterings. Overwatering is the most common mistake — avoid soggy conditions, which promote root rot. Reduce irrigation in fall to limit tender new growth before winter.

Soil & Fertilizer

Plant in well-drained, slightly acidic soil (pH 5.5–7.0). Fertilize with a citrus-specific granular fertilizer in February, May, and August — do not fertilize after August to harden growth before winter. Young trees benefit from freeze protection their first 2–3 winters in NE Florida.
