Why do those use epson saline surrounded by the garden?
I agree near both the above posters. It is used for both, but be careful if you are hard by any kind of water-based ecosystems, or rivers as too much of this is amazingly bad for them.
Epsom salts are magnesium sulfate... sulfate is an acidifier and magnesium is a trace factor that helps surrounded by the production of Chlorophyll.. plants need a LITTLE of the magnesium and Epsom salt is a way to tender it in a process the plant can use quickly.. too much is NOT correct..
it's ALUMINUM sulfate that is used on hydrangeas.. in need the aluminum, the blue wont' happen..
Answers: Epsom salts supply magnesium to the soil. They can be used around hydrangeas to make the flowers more blue. If the soil is too acerbic, flowers on the same plant will be pink. Epsom salt are usually cheaper than products sold to make hydrangeas blue, and they contain one and the same ingredient.
