3. Counter Transplant Shock
We’ve all seen how our plants and seedlings wilt when we move them from a small pot to a larger one, from indoors to outside, or from greenhouse to ground. Try feeding transplants with Epsom salt once they’re in their new environment to help injured roots overcome transplant shock. Remember to add a layer of soil on top of salt sprinkled in holes so roots don’t come into direct contact with these concentrated minerals right away.
4. Green Up Foliage
Plants that aren’t getting enough magnesium can be identified by their yellowing leaves. This is because magnesium is an essential component in the production of chlorophyll. Try sprinkling Epsom salt around your plants to achieve healthier foliage. About 1 tablespoon per 12 inches of height once a month will benefit the plants in your vegetable garden, as well as any trees, shrubs, flowers and grasses you want to green up.
5. Prevent Leaf Curling
Leaf curling may also be caused by magnesium-deficiency in plants. Again, add Epsom salt to the soil around the base of the sick plant. Alternately, for faster absorption you can mix 2 tablespoons of Epsom salt in a gallon of water and apply directly to the leaves.
