What it is
French Marigold (Tagetes patula) is in the Asteraceae (Daisy) family. More than pretty — a dense planting suppresses root-knot nematodes in the soil while feeding pollinators.
How to grow it
It wants full sun, water it low, and give it average soil. Target a soil pH around 6.0–7.5. Space plants about 8–10 in apart. Expect roughly 50–60 to bloom. Warm-season annual.
How it's used
French Marigold is used: cover; companion; flowers edible.
🔎 How to identify it
- Ferny aromatic leaves
- Orange/yellow/red flowers
- Bushy compact habit

How to grow & propagate french marigold
Everything I've worked out about starting this one, keeping it alive through a Texas year, and turning one plant into many — free.
How to propagate french marigold
The daisy family is a seed family — those flower heads are seed factories, and most members come up fast and willing from direct sowing. The perennial members (coneflower, black-eyed Susan, the native sunflowers) also clump up over a few years and can be lifted and split in fall or early spring to make free plants and keep the center from dying out.
Growing french marigold in Texas
Give it full sun and average soil. Match the spot to the plant and most of the battle is already won.
Time your planting to our long warm season and watch the frost dates at both ends; the live weather tool on this site is built for exactly that.
Keep moisture even, especially while it's young — deep, less-frequent soaks build better roots than a daily sprinkle.
Harvesting
Figure on roughly 50–60 to bloom before you're harvesting. The part you're after: petals (edible).
Making more for free
Every seed we sell is open-pollinated, which means you can save your own from the best plants and it'll grow true next year. Let a few of your strongest plants finish and go to seed, dry it fully, and store it cool and dark. That's the whole point of heirlooms — buy once, grow forever.
