They sent us a bazillion boxes of 1.2 solution, my husband only uses the 4.5, so we have tons of boxes that they won't take back, and some we had to store out in the garage, and they are for sure not usable cuz of the extreme heat----------so, my question is, could i just take the bags outside and cut them and drain them on the lawn and the plants and roses and stuff??? i hate to waste things, and it seems like the 1.5's would be good for plants------or maybe not, maybe i will kill everything? Anyone tried this? It has magnesium, that's supposed to be good for roses, right???Cindy
