How to Use Epsom Salt in a Garden
Epsom salt is not table salt, it is actually hydrated Magnesium Sulfate (10% magnesium and 13% sulphur) that offers an environmentally safe way to fertilize your garden. Magnesium helps plants during germination by strengthening the plant cell walls. It also assists in the creation of chlorophyll and helps plants absorb phosphorus and nitrogen. Sulfate also helps in the creation of chlorophyll and helps in the absorption of nitrogen, phosphorus, and potassium. Epsom salt can also help reduce salt in older soil which can clog the roots of plants. Epsom salt can make your plants bloom more often, be greener, and be healthier. Before applying Epsom salt to your plants, test your soil for its magnesium content to see if additional magnesium is necessary. Since Epsom Salt is also used for health purposes, you can often find it near the medicine or bath soap in your local store for around two or three dollars.
When planting new plants, mix 1 cup of Epsom salt per 100 square feet of soil before planting. Plant your plants in your garden as you usually would and water well.

You can even sprinkle 1 tablespoon of Epsom salt around a transplanted tomato or pepper plant to help younger plants thrive.
