I have a beautiful red columbine in a flower bed. I had many
compliments about it during May. It was fine just into June and now
it's leaning over and just looks tired. I've dead-headed it, but am
wondering if it's just done blooming and what do I do with it now?
This is the first one I've had. I bought it last year and it didn't
do anything last year which sounds normal for columbines. What do I
do with it now?
Any help you can provide is greatly appreciated.

Prune it back to something that looks somewhat civilized.
Columbine will get weedy-looking after the peak of bloom.
You won't hurt the plant by pruning it back to something
you can stand to look at.
