Hello,

I recently received my soil test results from the local university. My soil has a ph of 5.4. My soil is very high in Phosphorous, over 100 ppm, which I have heard is common for my area due to heavy use of fertilizers in the past. I just bought my house. Potassium is about 47 ppm. My soil is coarse and about 4% organic matter.

My question is, what are the best organic amendments to my garden soil to ensure healthy roses? I was told to get 15-0-40 fertilizer. As well, there is a recommendation to add 22lbs of lime per 100 square feet. What does this mean, and why is this recommended? I would appreciate any additional advice for healthy soils.
