Autumn Joy Sedum
My autumn joy gets so big that it flops over. I've heard that you can prune it back in early July. How far back can you prune and does it recover nicely? I would like to keep them more compact.

First, make sure that it gets plenty of sun to reduce the flopping. You can also pinch plants back to keep them compact and cut them back by half in May.
