Trimming purple fountain grass
I typically trim my plants at the end of February. I have noticed a lot of new green growth already this year due to a not normal warm California January through February. Should I cut the plants back to 6 inches now or leave them alone until next year?
You can cut them back now. This will help the new growth. If is fortunate that you will have this extra time in the season for growth, as here in my area it has been excessively cold this winter. It is just now finally warming up!
Go ahead and cut them, and let them continue growing.
