Care essentials
Plant grapefruit in full sun — a minimum of 8 hours of direct sunlight daily — for optimal fruit set and sweetness. In NE Florida, south- or southeast-facing exposures away from frost pockets are ideal.
Water deeply and consistently, keeping the root zone (top 12 inches) between field capacity and no more than two-thirds depleted; allow the soil to partially dry between waterings. Established trees in NE Florida typically need supplemental irrigation during dry spells; avoid waterlogged conditions.
Plant in well-drained sandy or loamy soil with pH 5.5–6.5. Fertilize three times per year (February, May, October) with a citrus-formula fertilizer that includes micronutrients; UF/IFAS recommends 1–1.5 lbs of actual nitrogen per tree per year for home landscape trees.
