How To Use Epsom Salt To Keep Slugs Out Of Your Garden
By ROBYN HUNT
Containing micronutrients
like sulfur and magnesium, Epsom salt can be used in its dry natural state as a barrier or as a foliar solution to ward off the slugs in your garden.
To make a saline spray, mix one tablespoon of Epsom salt with a gallon of water. Use warm water to ensure that the Epsom salts have completely dissolved.
Apply the solution with a pump sprayer, spraying directly onto slugs, and let Epsom salt's dehydrating power send these soft-bodied mollusks to their demise.
You can also sprinkle dry Epsom salt in a narrow strip around your plants. The salt's scratchy texture and dehydrating properties will damage the slug's sensitive skin and kill it.
