Can I cut back yarrow for a second bloom???
I live in central Virginia and the yarrow is just about finished blooming. The usual side shoots for smaller flowers are coming now and the older flowers heads are starting to darken.
I've had success with the following: I cut back all my cat mint to about six inches in height about three weeks ago. Now all the plants have new growth and are about a foot high with new flowers about to open. I'm happy.
So . . . Can I cut down my yarrow, say to about half it's normal height and get a second bloom time? Are there other perennials that respond with a second blooming if they're cut back??? Wouldn't THAT be great!!!
