Growing Marigold in Los Angeles

Los Angeles enjoys a nearly year-round growing season in Zone 10b. Frost is rare and brief, typically limited to a few nights in January. The mild, dry Mediterranean climate is ideal for warm-season vegetables most of the year, though cool-season crops like lettuce and broccoli actually prefer the mild winters over the hot, dry summers.

In Los Angeles (last frost around January 15), aim to direct sow or transplant marigold outside around January — 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.
