Okay to trim back sedums now to keep shorter
I'm wondering about trimming down sedums now to get shorter stalks on three two-year old Black Jacks. They grew pretty tall and think they'd look better shorter.
I remember reading on this site that you can trim sedum back, probably in half, and still get blooms in the fall. If I'm remembering right, the person posting said you could trim them back till June and still have flowers.
Can you verify if this is right?
