Do you want to do the Texas pruning method "Whack 'Em Back", or more shortening/shaping? I routinely shorten salvias because they grow way too large and floppy on the Gulf Coast, but I only whack em back in early spring and late summer/early fall. Just what I do...
I had to give away 'Wendy's Wish' - it got enormous fast last summer even w/ the drought and that was just its first year. It's now eating a bed at our master gardener gardens.
