Geraniums (Pelargonium × hortorum) are tender perennials grown as warm-season annuals throughout North America. Prized for their bold flower clusters, long bloom period, and tolerance of summer heat when planted in well-drained soil, they anchor window boxes, containers, and bed borders from late spring until hard frost. Zones 9b–11b can overwinter plants in the ground.

Colquitt County, Georgia is in USDA Zone 9a. The average last spring frost is March 7 and the first fall frost is November 20, giving you a growing season of approximately 258 days.

At an elevation of 211 feet, Colquitt County receives approximately 54.5 inches of rainfall annually with predominantly clay loam soil. Summer highs average 96°F, so Geraniums may need afternoon shade and extra watering during peak heat. Clay soil retains moisture well for Geraniums, but amend with compost to improve drainage and prevent root rot. Ample rainfall means less supplemental watering, but ensure good drainage to prevent Geraniums root diseases.

Geraniums 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.

Geraniums needs ~1,870 GDD — county provides 5,676 GDD Excellent fit
