Epsom Salt Fertilizer
Magnesium sulfate in Epsom salt corrects magnesium deficiency in plants — good for tomatoes, peppers, and roses that show yellowing between leaf veins.
What you'll need
- 1 gallon water
- 1 tbsp Epsom salt
Steps
- Dissolve Epsom salt fully in the water.
- Water plants at the base with the solution once a month during the growing season.
Tip: Only useful for magnesium-deficient soil — a soil test first will confirm whether your garden actually needs it.
