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.

Atkinson County, Georgia is in USDA Zone 9a. The average last spring frost is March 6 and the first fall frost is November 23, giving you a growing season of approximately 262 days.

At an elevation of 193 feet, Atkinson County receives approximately 57.5 inches of rainfall annually with predominantly clay loam soil. Summer highs average 95°F, so Nasturtium may need afternoon shade and extra watering during peak heat. Clay soil retains moisture well for Nasturtium, but amend with compost to improve drainage and prevent root rot. Ample rainfall means less supplemental watering, but ensure good drainage to prevent Nasturtium root diseases.

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 ~1,275 GDD — county provides 5,567 GDD Excellent fit

Growing Tips for Nasturtium in Atkinson County

Direct sow Nasturtium outdoors after March 06 in Atkinson County when soil has warmed and frost danger has passed.

With Atkinson County's clay soil (34% 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.
