Our take on the Monterey Epsom Salts (4 lb)

Monterey Epsom Salts is a magnesium sulfate garden amendment in a 4 lb shaker can. It supplies 9.8% magnesium and 12.9% sulfur, nutrients plants need for chlorophyll and for taking up phosphorus. It is OMRI listed for organic production and can be taken up through both leaves and roots, so it works as a soil drench or a foliar spray. Gardeners use it mainly to correct yellowing leaves from magnesium deficiency. Compared with plain bulk Epsom salt, it costs more but comes with a shaker can and a clear nutrient analysis.
