when the flower is spent, you may pull off the head or clip it off just below the base unless you notice that it is setting seeds. In that case wait until the seeds are mature then pick the seeds off and save to plant. Good luck.

Reply:Cut the whole thing off down to the first set of leaves. if you let some Annuals set seeds they will die shortly thereafter cause they have done what they were intended to do... ensure the species survival.
