Epsom salt is magnesium sulfate.
Magnesium is part of the chlorophyll molecule and vital for plants to grow. If it is missing in the soil, plants won’t grow as well, and adding magnesium to the soil will help. Epsom Salt does not build up in the soil over time, so it is very safe to use. Trees, especially if the bloom and fruit can benefit from Epsom salt by allowing more minerals to be absorbed through the roots, giving you strong healthy trees to enjoy for years to come.
