I've got several tomatoes in the conservatory (aka the greenhouse) and as it gets jolly hot in there (it's south-facing) I have to do a lot of watering. I have been feeding with Tomorite, but it looks as if the toms are a bit magnesium deficient so I have procured some Epsom salt from the chemist. However, the only instructions on the box relates to mild constipation :o and that's not of much help regarding my toms! I'm assuming I just dissolve the salt in some luke-warmish water, but how much should I use and how much per plant? :-\
Dilute a tablespoon of Epsom salt in a gallon of water will do fine .
You can use it a s foliar spray as well for blossom drop at the same dilution.
Some people just sprinkle a little in a ring around the plant.

Garden use of epsom salts
I used 1/2oz/pint in a sprayer and Robert was indeed my Mothers Brother ;D
Thanks guys, at least I know that the amount I'd used wasn't going to kill the plants! Seems an awful lot what they said in that article, but at least I know that I can use it quite liberally. And Robert was actually my mothers father! ;D
