Deadhead to prolong flowering; when it's coming to the end of the season, let it go to seed to feed the birds and so you can save some for next year!

Sprouts Top Tips
Used to hotter and drier parts of the world than Britain, your Cosmos will do best in well-draining soil with plenty of light. Make sure it gets a drink if there is a drought. If you want more next year, collect some seeds once it finishes flowering in about October, and store them somewhere cool and dry to sow the following year.
