In early fall I had a soil test done. I live in zone 5a Chicago suburbs. My Magnesium levels we're off the charts. I grow 55 roses, all flowered and look well, but I would like to try and correct the magnesium levels. Will sulfur do the trick?
Thanks for any help
No, I didn't add any epsom salt, that is why it is so puzzling to me. I know you shouldn't water with softened water, but the bypass is so hard to turn on the softener, so if my husband isn't home to adjust it for me, I just go ahead and water.
I tried to find information on watering with softened water and the effects but I didn't have much luck. Someone advised growing a cover crop to leach out the magnesium, but that would be a big mess in my mind.
Thanks for your help.
