salty

Tomatoes and peppers relish a spoonful of Epsom salts because the white crystals contain magnesium. All plants use magnesium for photosyntesis and most soils contain an adequate supply, but using Epsom salts as a fertilizer for these plants increases their flower and fruit production. Epsom salts help roses grow in the shade as well.

Add five millilitres of Epsom salts per litre of water to your roses' fertilizer three times during the growing season.

I think I've over salted my Office Gardenia.
