Water deeply every 7 days, ensuring the pot or ground drains well. Let the top inch of soil dry out between waterings. Never allow roots to sit in standing water, as this causes root rot. Reduce frequency in winter.

Key lime demands full direct sun â at least 6 to 8 hours per day. Indoors, place directly in front of a south- or west-facing window. Insufficient light drastically reduces fruiting and weakens the tree over time.
ðŠī Ideal Soil
Plant in well-draining, sandy or loamy soil with a pH of 5.5â7.0. Avoid heavy clay soils that retain moisture. In containers, use a quality citrus mix amended with perlite or coarse sand to ensure excellent drainage.
