Mulching around the rose bushes
I normally put down a layer of cedar shredded mulch around all my rose bushes. Then around December before bad freezing--I put my collars around the bushes & fill the collars with the existing mulch. Now in Spring, after I took the collars off, I gently raked all the old mulch off & disposed of. I've heard to wait to add new mulch til the roses start to get more foliage. So, should I be adding new mulch now or wait? Thanks.
Also, can anyone out there tell me what the most disease resistant hybrid teas are? I've pretty much stuck with those type of roses except for a few David Austin Old English. Love hybrid teas. Not crazy about the floridbundas. Thanks.
