I use Miracle Gro on my roses, but I'm a chemi-head. You can also use good organic stimulants on 'em.
I use Miracle Gro on about everything but the dog. ;-) It works pretty well, if my loco pansies and petunias last year are any indication.
Well...after the poor hummingbird flying by last night, I felt guilty about not stopping for a feeder. Got it and a fairly short shepherd’s crook, so I st it up just outside the door. If it proves too tempting to the dog, I’ll get a taller one and use that one for flowers. I don’t think he’d mess with hanging flowers if they were actually hanging, instead of sitting on the ground waiting to be put on hangers. He thought the hooks make a dandy handle...
