Care essentials
Light
Nasturtiums grow best in full sun in NE Florida; plant in fall for winter-spring color — avoid planting in summer heat, which causes decline.
Water
Water moderately and consistently; nasturtiums prefer slightly lean, well-drained soil — excess fertility or wet soils promote foliage at the expense of flowers.
Soil & Fertilizer
Thrives in average to poor, well-drained sandy soils; avoid heavy fertilization which reduces flowering. In NE Florida, sow or transplant October–February for best winter-spring performance.
