Nasturtium (Tropaeolum majus) is a fast-growing annual with distinctive round, lily-pad leaves and bold trumpet-shaped blooms in warm oranges, reds, and yellows. Both the flowers and leaves are edible with a peppery watercress flavor. Planted near vegetables, nasturtiums act as a sacrifice trap-crop, luring aphids away from more valuable plants. They thrive in poor, dry soil — rich conditions produce lush foliage but few flowers.

Baldwin County, Georgia is in USDA Zone 8b. The average last spring frost is March 23 and the first fall frost is November 8, giving you a growing season of approximately 230 days.

At an elevation of 421 feet, Baldwin County receives approximately 59 inches of rainfall annually with predominantly clay loam soil. Summer highs average 91°F, providing good warmth for Nasturtium during the growing season. Clay soil retains moisture well for Nasturtium, but amend with compost to improve drainage and prevent root rot.

Nasturtium Heat Requirements (GDD)

What are Growing Degree Days (GDD)?

Growing Degree Days measure the total warmth your plants receive during the growing season. Think of it as a "heat bank" — every day above 50°F deposits warmth that helps your plants grow.

Each plant needs a certain amount of accumulated heat to mature. If your county provides more GDD than the plant needs, it's a great fit. If it's close, you may want to choose faster-maturing varieties or start seeds indoors to get a head start.

Nasturtium needs ~1,095 GDD — county provides 4,197 GDD Excellent fit

Growing Tips for Nasturtium in Baldwin County

Direct sow Nasturtium outdoors after March 23 in Baldwin County when soil has warmed and frost danger has passed.

With Baldwin County's clay soil (30% clay), work in 3-4 inches of compost before planting Nasturtium. Avoid tilling when soil is wet to prevent compaction.

General growing tips

Direct-sow large seeds 1/2 inch deep after last frost; soak seeds overnight to speed germination (7-10 days). Nasturtiums dislike root disturbance so direct sowing is strongly preferred. Avoid fertilizing — poor soil brings the best bloom. Trailing types can cover banks and climb trellises; dwarf types suit containers. In hot climates (zones 9+) plant in fall for winter/spring bloom as plants struggle in peak summer heat.
