Epsom Salts

Hi I just bought a large amount of Epsom Salts for my garden as I was told it is good for my Roses, but I was wondering if there are any plants which don't like it so I know to avoid using it on them?

    Jan, Magnesium Sulphate is best dissolved in water and used directly on the plants as a foliage feed, it is easily dissolved in water. Can be used on Peppers, Roses, Potato's, Tomato's and Carrots. Added to soil it adds magnesium which should not harm other plants as it is soon diluted and washed away by rain.


  • Thanks Frank I did realise it would be best dissolved in water but did not know about the peppers,potatos, tomatoes and carrots, so thanks for that helpful information.

  • I sprinkle it in with the chopped up banana skins (K+) with household paper shreddings as a carrier rotted down in an airtight container to feed tomatoes. Seems to work, I picked the last of my tomatoes yesterday ... thought I'd never get the greenhouse cleared for this year's stuff. 

    I don't need massive quantities and found Savers to be the cheapest
