Epsom Salt Pesticide
Epsom salt has many great uses in the garden – one of which is as a pest deterrent and pesticide.
Spraying and sprinkling are two of the most effective ways of using these magnesium rich salts to combat bugs.
To make an Epsom salt spray, dissolve one cup of the salts (available from here) in five gallons of water. Decant into a spray bottle and apply to the affected plants. This will work to burn slugs and beetles, ensuring they keep their distance.
An easier option is to simply sprinkle the salts around the base of your plants, reapplying every other week. This will not only deter pests, but will also increase nutrition absorption, as magnesium helps plant roots take up vital nutrients like nitrogen, phosphorus and sulfur.
