What is the best fertilizer bloomer for roses.
I put a couple of handfuls of semi-composted sheep manure (that I dug out from under a sheep shearing shed) around them twice a year. I get about 40 blooms at a time during the summer. The manure that is well rotted soaks right in as you water it, and the stuff that is still in pellet form rots down slowly and feeds the plant all year. I feed them after I prune them for winter and then again in spring. I also do this wih my orange tree and get about 250 oranges at once. I know nothing about gardening but it works for me.
