Do marigolds come stern twelve-monthly,and do they necessitate much fertililizing?
Answers: I live in zone 5 contained by north Missouri, and my marigolds come back every year from the seed they drop off within the fall. . . I also deadhead them within the fall and salvage the seeds for subsequent year also. 1 packet of seeds I bought 5 years ago, are pliable me over 1,000 plants now. . . GL!
Edit: By the passageway, I don't fertilize and of course they are annuals :)
Don't know your zone, or the type of marigolds you are using, but most folks consider them annuals. (replant yearly) . They can come fund from seed. If it is a hybrid or anything specially bred, seed may not be viable, or at least not true to type. It is other fun for me to see what happens, They are not pouring feeders.
