In Colorado, while my African marigolds were in full bloom, they were hit by an early freeze. Can I now take off the blooms and allow them to dry out to use the seeds? Thanks
My understanding is that seeds need to be left on the plant to mature. Picking them too early will stop the process. A freeze should not prevent the seeds from maturing.

acquired a 3' marigold bush that had been resting in water. looking full & healthy. gave her a small root trim before transferring to 3gallon clay pot w/ fresh soil & a tad MiracleGro*. did not overwater. 3 days later: she has withered. dry, very unhappy. i feel awful. so... not enough sun? need larger pot? watering ? SOS PLEASE
How long had it been resting in water? It may have gotten root rot while resting. Also, plants living in water or rooting in water for a length of time have a hard time acclimating to soil culture.
If it's not a root problem, it could be something else, as described in this article:

I would like to know if French marigolds will survive wintertinein zone 6b?
Being an annual, they will grow just about anywhere! They will not reseed in any climate outside of zone 9 and up, though. If you let them go to seed and collect them, then you can save them in a warm spot for next year!

I would like to grow marigolds for consumption for eye health, so I would like to know the very best marigold seed for that purpose. In addition would like to purchase some live marigolds immediately for consumption, until I get a crop going, but my local Home Depot marigolds say can cause cancer or reproductive harm on the container!!! Can you help me with these issues please. Thank you. Tricia
I didn't see any reference to eye health from consuming marigolds in my research. They are used for garnish on salads mostly. More references cited calendula petals as edible, rather than marigold. We do have an article that gives edible marigold varieties, however. I would suggest visiting with a health food store owner for her input on eating marigolds. And only eat the petals of either type.
