Sorry. I am glad I asked. I misread your statement.
Question: Is Epson Salts a good supply for magnesium?
Thanks.


Yes. It also might be useful to break up a clay soil, but gypsum,
calcium sulfate, is usually recommended. Too much magnesium can be
bad, like too much of anything. I use a tablespoon in water, once a
year, per rose bush.
