Epsom salt foliage spray for plants is an excellent option, as when sprayed on the leaves, this is easily absorbed by the plants, as compared to absorption from soil. Many gardeners suggest that certain plants like tomatoes and pepper, have better absorption of minerals when sprayed with Epsom salt with water.
A study conducted on gardeners for testing Epsom salt, concluded that the method of diluting it with water and using as foliar spray was more reliable to ensure that plants absorb and get their mineral content. Plants will not absorb dry magnesium, specially in alkaline soil, where potassium content is already high. So, a foliar spray is most recommended.
This salt as we know is easily available, and most of the packages will contain instructions on how to use it effectively. For foliage sprays the most recommended dosage is: dissolve 1 tablespoon of this salt for each gallon of water.
Epsom salt spray for plants is just another remedy for gardening that is easy and beneficial. So do not simply over-do spraying. Give the plant just the right amount of shower with this spray, at right intervals!
