Deadheading cosmos flowers
Cosmos usually starts blooming in early summer and continues until frost if you deadhead. While you don't have to deadhead, doing so keeps the planty looking tidy and encourages a quick rebloom.
How do you deadhead a cosmos plant?
A good tip for deadheading Cosmos is not to just take the flower head off, but cut the stem right back to the first leaf below the flower head. Once you have cut the Cosmos flowers, put them straight into water. If you pick them just as the buds are about to bloom, they will last 7 to 10 days.
