Epsom Salt for Plants
“Simple, Natural, and Surprisingly Effective.”
🌿 What is Epsom Salt?
Epsom salt is magnesium sulfate (MgSO₄·7H₂O) — a naturally occurring mineral compound that helps boost plant health, especially for leafy greens, flowers, and fruit-bearing plants. Despite the name, it’s not actual table salt and is entirely plant-safe when used correctly.
