Impatiens (Impatiens walleriana) are the go-to annual for shaded beds and containers. They produce a continuous carpet of flat-faced blooms from transplant until frost, needing little deadheading. Their preference for consistent moisture and part-shade makes them ideal under trees and along north-facing borders.

Bryan County, Georgia is in USDA Zone 9a. The average last spring frost is March 2 and the first fall frost is November 24, giving you a growing season of approximately 267 days.

At an elevation of 193 feet, Bryan County receives approximately 54 inches of rainfall annually with predominantly sandy loam soil. Summer highs average 92°F, providing good warmth for Impatiens during the growing season.

Ample rainfall means less supplemental watering, but ensure good drainage to prevent Impatiens root diseases.

Impatiens 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.

Impatiens needs ~1,282 GDD — county provides 5,073 GDD Excellent fit

Growing Tips for Impatiens in Bryan County

Direct sow Impatiens outdoors after March 02 in Bryan County when soil has warmed and frost danger has passed.

Sandy soil in Bryan County dries quickly — mulch Impatiens with 2-3 inches of straw and water deeply 2-3 times per week rather than lightly every day.

General growing tips

Start seeds indoors 8–10 weeks before last frost at 70–75°F; germination requires light — do not cover seeds. Transplant after last frost once nights consistently exceed 50°F. Water regularly — wilting causes bud drop and they rarely fully recover the same flush. Watch for impatiens downy mildew (IDM); consider New Guinea impatiens as a resistant alternative in affected regions. Pinch tips at planting to encourage branching.
