Epsom salt is a simple, multi-purpose garden tool that can help with everything from pest control to plant health when used correctly. Sprinkling it around your garden or patio may help deter slugs, while adding small amounts to the soil around roses or other plants can support growth and nutrient uptake. It can also be used as a light fertilizer for vegetables, houseplants, and trees, and even diluted in water to help promote greener lawns. Beyond the garden, spreading it near garbage areas may discourage pests like raccoons, though it needs to be reapplied after rain. Used in moderation, it’s an easy and affordable way to support a healthier, more resilient outdoor space.
