Got my Potash & Magnesium sulphate mixed up!

Hey everyone,

A few days ago I'd bought a box of Miracle gro Potash and a box of Miracle gro Epsom salts.

I'd been using them on my palm trees and then it started raining (wetting the cardboard boxes) so i stupidly continued by taking the bags out of the boxes (now i have no idea which is which)

Does anyone happen to have used these before and know which are the round shaped balls and which are the small gravel textured ones?

 

I might recognise from photo. Epsom salt crystals tend to be geometric and slightly translucent. They do taste different, but I wouldn't recommend that you do, though a crystal of either will not hurt.

 

I think Epsom salts are more soluble than potash

 

Alas. I am not a chemist. When it comes to chemicals and drugs, I pass to my Hon. friend Nigel.

 

Don't think I've ever bought them in that form.

 

@PhilC Thanks for the pictures. Like Pete I don't recognise either, certainly the Epsom salts I have used has been white crystals with a tendency to absorb water.
Good news I remembered I had a box of Miracle Gro Magnesium Salts in the shed so a quick scoot out and what I have is in a white bag and looks most like the RHS picture. I'm not sure exactly what it is, but the box states that it contains 15% more magnesium than traditional Epsom salts.
So the LHS photo is most likely the Miracle Gro Sulphate of Potash.
I think they are produced from crushed rock, which is why they look a bit like gravel, with little refining and they will probably be slower release than traditional Epsom salts or potassium sulfate,

 

Do you mean it contains 15% Mg or 15% more Mg? Im thinking it might be kieserite which is a granular form of magnesium sulphate

 

Never said im quick lol
