When to Plant Nasturtium in Gloucester County, VA

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.

Gloucester County, Virginia is in USDA Zone 8a. The average last spring frost is April 1 and the first fall frost is November 4, giving you a growing season of approximately 217 days.

At an elevation of 817 feet, Gloucester County receives approximately 52.1 inches of rainfall annually with predominantly silt loam soil. Summer highs average 91°F, providing good warmth for Nasturtium during the growing season. Ample rainfall means less supplemental watering, but ensure good drainage to prevent Nasturtium root diseases.

Growing Tips for Gloucester County

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.
