When I plant marigolds, I just direct-seed them but they're such nuisances:
If not constantly deadheaded, marigold seedlings come up for years afterward.
I've found them ineffective in repelling nematodes, their reputed "wholistic"
gardening value, and see little point in attracting pollinators -- honeybees, in
particular -- to blossoms other than those of my food crops.

Not all marigold varieties are effective against nematodes. French
Marigolds are more effective than Aftican Marigolds for instance.

Seeing as my saved seed doesn't cost me anything, I see no problem
replanting them each year.
