Sul-Po-Mag 0-0-21.5 Sulfate of Potash Magnesia (K-Mag) "Greenway Biotech Brand" 50 Pounds

Sol -Po- Mag is difficult to find in our area so I loved the fact that I could order it . It arrived quickly and in time to feed our plants.

I used this in the fall on my roses so I won't know the results until this spring. I used it to increase the odds of the roses surviving the winter in great shape. We have snow on the ground at the moment and I do not see any yet and probably won't until April.
