Feeding container roses - What are some recommended methods?
I've got a couple roses in containers that I started as bands last summer. (Fingers crossed they survive the polar vortex that is January in my unheated garage.) I'm not sure how to fertilize them. I'm assuming that I can't use the same formula I use on their in-ground cousins. Plus, they're heavier feeders. I followed the 'don't fertilize bands in their first year' rule last year. Should I use a liquid? A slow release granule? Do they need feeding more often? Less often? Thanks!
