can epsom salt be used on all plants
Overview. Epsom salts help nourish your houseplants by providing magnesium--the building block of leaves' green chlorophyll pigment. Also known as magnesium sulfate, Epsom salts dissolve readily in water and absorb into roots when soaked into the soil. Being organic, these nonsalt crystals do not harm plants, even when you accidentally add a bit too much when making a dosage.
