Are Epsom Salts In The Garden Good?

When used in the garden, Epsom salt is known as magnesium sulfate. It is a mineral that helps seeds germinate, makes plants grow bushier, produces more flowers, increases chlorophyll production, and deters pests.

It is a great addition to any fertilizer or as a supplement to fertilizers that don’t have this mineral in them already. Here are a few reasons to use Epsom salts for your plants, gardens, and your lawn.

  • Boost Seed Life – Magnesium boosts seed germination by giving seeds more energy and strengthen cell walls.
  • Better Absorption Of Nutrients – It has been scientifically proven that that magnesium-sulfate can increase the ability of seeds and plants to absorb nutrients.
  • Eliminate Root Shock – Plants tend to go into root shock when taken from one bed or pot to another. But Epsom salts in the soil can help make the transition easier.
  • Keep Pests Away – Epsom salts can keep away bugs and other pests that can ruin your plants. While other materials can do this, they can also harm your plants, so it is counterproductive.
  • Make Plants Greener – It’s a known fact that yellow plants can mean magnesium deficiency. So, adding magnesium sulfate can actually reverse that deficiency.
  • More Flavorful Veggies – Epsom salts can really make your fruits, veggies, and other edibles more flavorful. Since it is safe to use on edible plants, this is really a no-brainer.
  • Greener Lawns – Of course, if Epsom salts can make plants greener, they can make grass greener too. So, if your lawn is yellowed, try sprinkling it with some salts to bring it vibrancy.
  • Healing Powers – Epsom salts are pH neutral and gentle on plants. They can do all sorts of wonderful things for your plants, so they just might be the magic you need.
