10 Incredible Uses for Epsom Salt in the Garden
1. Improve Seed Germination
Using Epsom salt as a soil amendment before seeding will give your garden a powerful boost right from the start. Magnesium aids in seed germination and helps to strengthen cell walls, leading to more and stronger seedlings. For best results, incorporate 1 cup of salt per 100 square feet of tilled soil or mix 1 – 2 tablespoons into the soil at the bottom of each hole before dropping in seeds.
2. Increase Nutrient Absorption
Many commercial fertilizers add magnesium to help plant roots take up vital nutrients (nitrogen, phosphorus, sulfur.) For those using all organic materials to feed their gardens, adding Epsom salt to soil will improve absorption naturally, eliminating the need for processed chemical fertilizers.
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.
