Why Epsom Salt ?

Aphid · May 23, 2011

Why should I be adding Epsom Salt to the planting hole and how does it stop Blossom end rot ?

I keep hearing this solution but no one can tell me why,, I thought epsom salt was magnesium .

My fertilizer contains magnesium plus I use Dolomite,,, what is so magical about epsom salt ?

I did a little digging and found that way back in the 1920s'ish and even earlier people used epsom salt to replenish the soil from intensive crop production
It's not like they had a lot of options for fertilizers and amendments back than

Is this just another home remedy that has simply been passed on from generation to generation ? or is it a must use amendment for tomatoes and peppers?

also does it really "stop blossom end rot" ?
