Are Epsom Salts Safe?

This is a question we hear a lot and you are right to raise concerns when it comes to your plants, your pets, and your family. Most of the time, though Epsom salts cannot hurt you. However, there are some things to remember.

Don’t leave them down around kids or pets. Ingesting Epsom salts isn’t always safe. Especially if there are perfumes added to them, which is common for Epsom salts used for baths. Use plain Epsom salts for an added safety measure.

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.
