Beginner Gardening: Do Marigolds Come Back Every Year or Do They Reseed?, 1 by gardenstarts

I’ve had a lot of people ask if marigolds come back every year, and it can be a little confusing.

Technically, marigolds are annuals, so the original plant won’t survive winter. Once frost hits, they’re done for the season.

But here’s what I’ve noticed over the years—they can act like they come back. What’s really happening is they reseed themselves. If you let some of the flowers dry out and drop seed, those seeds will often come up the following spring.

A few things that seem to help if you want that effect:

Leave some blooms on the plant late in the season
Don’t clean up beds too aggressively in the fall
Try to leave the soil undisturbed where they grew

In warmer areas or protected spots, I’ve seen them reseed even better.

That said, I’ve always had more consistent results just planting fresh seed each year—plants come up stronger and bloom more evenly.

I put together a more detailed guide with planting timing and tips if anyone wants to dig into it:

Curious what others have seen—do your marigolds reseed reliably, or do you replant every year?
