Epsom Salt ???

9 years ago

I've heard a lot of discussion about using epsom salt in soil . Not only using it in a garden & vegetable garden , with your normal tomato plants , geraniums , petunias , etc ... but using it with succulents/cacti . Whats the significance of this , is it even safe to use ? If so , how do I go about putting it to use with my succulents/cacti ?

Personally, I don't use Epsom Salt, so I don't know the reasons behind using it. However, I would think that it is safe to use.

Epsom salts are made of magnesium sulfate, which is very good for house plants.

Magnesium and sulfate are minor nutrients, so plants do not need lots of it. It is not a miracle ingredient...it's NPK is 0-0-0. It shouldn't be added unless one is sure there is deficiency of both magnesium and sulfur. If only sulfur is needed, it is better to use horticultural sulfur.

There are lots of myths out there...using even 'good things' willy-nilly is not going to be of benefit.

Magnesium and calcium need to be at the right ratio for the uptake of either to be optimal. In clay, Ca:Mg may need to be 7:1 and in sand it may need to be 3:1, so if things are fine, I wouldn't mess with it. Likely at the "center" of the myth is the fact that every chlorophyll molecule has a single magnesium atom so more is good, right? Since that may be true in some cases, we, being the generalist that we are, assume it must be good everywhere.

Some facts on Epsom Salt.
