Will epsom salt harm hosta plants?

by Anonymous
Epsom Salts can be a fertilizer but I was also told it will accelerate the rotting of a tree stump. Hostas were planted at the base of the tree. So will it fertilize the hostas while it simultaneously rots the tree stump?

    Take a look at both of these sites. As for rotting tree stumps it seems a matter of too much of a good thing. If you drill holes in the tree and dump the epsom salt in it will kill the tree. So will bagged fertilizer. Make sense?

    Hello. I put Epsom salt down by my hostas to keep the slugs from eating them, and they do just fine!

    Epsom salts are good for greening lawns quickly. That's all I would use it for. Rather than spend money guessing what your soil needs, contact your County Agricultural Extension Office and get a soil test done. It's only around $10.00 and the people there are very helpful with any questions about your local growing region.

    Put them ON the stump... they're like any salt.. humidity makes them migrate, and the hostas will get the benefit.

    Also, Intense nitrogen can decay a stump. - Same idea.

    The most abundant element in Epsom Salts is magnesium... in low concentrations it benefits almost any green plant.
