Celosia Plants – When To Cut Back

Q: Our celosia plants bloom in late summer. They return each year with new
plants in different areas. When is a good time to cut them back? 

A: It is not uncommon for celosia to reseed itself. If you want this to happen
each year, cut them back after the leaves and flowers have turned brown.
Scuff the ground with your shoe wherever you would like new flowers to
grow and shake the flower heads over it so the tiny black seeds fall out. Gently
pat the seeded area with the sole of your shoe you’re all set for next year.
