When to Plant Nasturtium in Florida

Growing Nasturtium in Florida: Complete Guide

Nasturtium (Tropaeolum majus) is a crop that grows best when sown directly in the garden. In Florida, the right time to direct sow is around Thursday, January 8, 2026, once soil temperatures are consistently warm enough for germination.

Because Florida stretches across 7 USDA hardiness zones (8b, 9a, 9b, 10a, 10b, 11a, 11b), planting windows can shift by as much as six to eight weeks from one end of the state to the other. Gardeners in the warmer southern zones can start earlier, while those in cooler northern zones should wait until the zone table above shows their last frost has passed.

With 60 days to maturity, Nasturtium fits comfortably within Florida's growing season in most zones. In the warmest parts of the state, a second planting later in the season may be possible.

Nasturtium requires full sun to partial shade and low (drought tolerant) moisture. Southeastern summers are hot and humid; mulch heavily to retain moisture and shade roots during peak heat.
