Growing Marigold in Mobile

Mobile's Zone 8b Gulf Coast location in southwest Alabama provides one of the longest growing seasons in the South — approaching 275 days. The warm, humid climate supports a nearly year-round gardening calendar. Cool-season crops thrive from October through April, and warm-season crops fill the spring and summer months. Mobile's high annual rainfall (65+ inches) reduces irrigation needs but increases the importance of good drainage and fungal disease management.

In Mobile (last frost around February 27), aim to direct sow or transplant marigold outside around March — approximately 2 weeks after your last expected frost. Starting seeds indoors 6 weeks before the last frost date gives you a significant head start.

Marigold thrives between 55°F and 90°F. It is frost-sensitive, meaning a single freeze at 32°F will damage or kill it — always wait until frost danger has fully passed. Expect 45–55 days from transplant to first harvest. Great companion plant — repels pests. Easy and fast-growing.
