Has anyone tried cutting them back and having them bloom again? They're so pretty, I really don't want to pull them up. Plus, if I do, I'll have to make another nursery run for another round of plants to rent.
Possibly soil issues. You can propagate them from cuttings.
I cut petunias back they re-bloom beautifully in a few weeks.
Yay, so it can be done! Thanks, Pattywhack.
