how to take care of rose bushes from planting, to feeding, to pruning, to getting them to bloom in the spring and early summer. I have 8 of them and 5 of the 8 look like they are dead. There are old stems on them from last year and the bottom is green, but only 1 stem out of 5. HELP! I dont want to lose all these plants. Is there anything that I can do to save them or are they a lost cause already??
