Hi Jamie,

well - not really, magnesium sulfate (Epsom salt) is an additive used when planting
tomatoes, peppers and roses. It is recommended to use it only, when analysis has
proven the soil deficient in magnesium. It is used by some as an additive in the
bottom of a planting hole. In your case in combination with the root growth promoting
potassium, it is probably meant to do just that. In roses Epsom salt supposedly promotes
bloom and in tomatoes and peppers it is reputed to make the fruit sweeter. But that
appears to be mostly the case, if the soil was deficient of magnesium in the first place.

To sum it all up: You can use it as described above or spray it on foliage at a rate of
1 tbl spoon/gallon of water, but it probably 'ain't gonna' make a whole lot of difference,
unless your soil is lacking magnesium. For all I can figure out the main benefit of
the stuff is probably to the bottom line of its manufacturer.

Best,
Olaf
