Q.What Should I Feed My Roses And Use To Mulch
I tested my soil and found that the phosphorus levels are really high! Also my ph is very alkaline! I normally feed my roses a slow release food but after testing my soil am extremely wary of what I should feed them and when? Plus also how to lower my ph level as organically as I can? Which would be the best mulch to use now this spring? I normally use farm manure / horse manure?

Look for a good organic rose food with as little phosphate in it as possible.
