Hello everyone. Welcome back to the podcast. Kevin here from Epic Gardening. Today we are talking about

Epsom Salt. A lot of people talk about it and it's recommended for almost everything it seems like so what does it actually do

what is it and why is it so recommended the first thing we have to ask is, what is it? It's a chemical. It is consisting of

magnesium, some sulfate, and some water. The water is kind of tied up in it so you don't need to worry about the water but magnesium is a

nutrient that plants need to grow it's not a macro nutrient it's definitely a minor

nutrient plants don't need a ton of it, but they do need it.

Sulfate is sulfur and oxygen.

Plants can absorb sulfate directly from the soil

and use the sulfur molecule, but it is also another minor nutrient. Now epsum salt as a fertilizer

can work. It is effective if your soil is deficient of magnesium or sulfur.

Most garden soils, however, are not deficient in magnesium or sulfur.

Most garden soils.

Not to say all of them, but definitely most don't have that problem. So if you're

adding any kind of organic material, any kind of organic mulch, almost always your

soil is going to have enough both magnesium and sulfur.

If you have an acidic soil, you might have a deficiency because then the plant

roots can't uptake it within that pH range.

Sandy soil could also be an issue, but really unless you're doing a

soil test you need to just assume that you have enough unless you have done a

soil test and you know for a fact that you don't.

An MPK for Epsom Salt is a zero zero zero. It's a zero zero fertilizer.

That's just the truth.
