What is Epsom Salt?

Epsom salt is a naturally occurring mineral that has many benefits for plants. Additionally, Epsom salt can help with the germination of seeds and the growth of young plants. When used as a fertilizer, Epsom salt helps plants by providing them with essential nutrients they might not otherwise have access to. For example, Epsom salt contains magnesium, which is necessary for plant growth. Magnesium helps plants to develop strong roots and produces chlorophyll, which helps plants to photosynthesize and produce food for themselves. Additionally, Epsom salt can help loosen compacted soil and increase drainage in clay soils.

This allows plants to access better the water and nutrients they need to grow. As a pest control measure, Epsom salt can deter aphids, slugs, and other pests from eating your plants. Sprinkle some around the base of your plants or on top of the soil before planting. Also, make a spray solution by mixing one cup of Epsom salt with two cups of water and spraying it on the affected areas of your plants. To use Epsom salt for seed germination or young plant growth, add salt (one tablespoon) per gallon of water and apply it to the soil around your seeds or young plants.
