Will zinnias grow back after cutting?

Zinnia flowers produce large amounts of seed. Cut back the faded flowers early in the season to direct the plant’s energy toward producing more flowers rather than setting seed. You don’t have to wait until they’ve faded to cut the blooms.

After zinnias flower, cut off the old flowers (a process called “deadheading”) to encourage more flowers to form. Zinnias are annuals and will die with the first fall frost. If you want them to reseed, let the last flowers of the season mature fully and scatter their seeds.
