Bloom season. Good planting window.
Bloom season.
Growth slows as temperatures cool.
Retains foliage through winter. Can be planted in mild winter periods.
Kumquat grows best in full sun (6-8 hours) in NE Florida. It tolerates some shade but fruit production and quality decrease. Choose a warm, wind-protected location to minimize freeze risk in zone 9b.
Water deeply when the top inch of soil dries out; kumquats are moderately drought-tolerant once established. Avoid waterlogging — use well-drained soil and keep mulch away from the trunk to prevent foot rot.
Grow in well-drained sandy or loamy soil. Apply a citrus-specific fertilizer with micronutrients every 6 weeks from February through October. Kumquat is among the most cold-hardy citrus (tolerates 16–20°F) and is reliable throughout zone 9b; fruit ripens October through March.
