Epsom Salt Helps Plants Grow
Epsom salt is actually magnesium sulfate and contains key nutrients for plants and vegetables. It helps seeds germinate, makes plants grow bushier,produces more flowers, increases chlorophyll production and deters pests, such as slugs and voles. While it is not intended to replace your regular fertilizer, it will provide vital nutrients to supplement your regular fertilizer.
Following tips are useful for using Epson salt to grow the plants:
- Garden Startup: Sprinkle 1 cup per 100 square feet. Mix into soil before planting.
- Peppers: Mix 1 tablespoon of Epsom salt with a gallon of water and apply as a foliar spray at bloom time, then again 10 days later.
- Tomatoes: Add 1 tablespoon diluted in water per foot of plant height per plant; apply every two weeks.
- Houseplants: 2 tablespoons per gallon of water; feed plants monthly.
- Roses: Add 1 tablespoon diluted in a gallon of water per foot of plant height every two weeks. Also scratch 1/2 cup into soil at base to encourage flowering canes and healthy new basal cane growth. Before planting, soak bushes in 1/2 cup of Epsom salt per gallon of water to help roots recover. Add a tablespoon of Epsom salt to each hole at planting time. Spray with Epsom salt solution weekly (1 Tbsp per gallon of water) to help discourage pests.
- Shrubs (evergreens, azaleas, rhododendron): Add 1 tablespoon per 9 square feet by diluting in water. Apply over root zone every 2-4 weeks.
- Lawns: Apply 3 pounds for every 1,250 square feet with a , or dilute in water and apply with a sprayer.
- Trees: Apply 2 tablespoons per 9 square feet by diluting in water. Apply over the root zone three times annually.
- Sage: Do not apply! This herb is one of the few plants that doesn’t like Epsom salt.
Although magnesium and sulfur occur naturally in soil, they can be depleted by various conditions, including heavy agricultural use. Unlike most commercial fertilizers, which build up in the soil over time, Epsom alt is not persistent so you can’t overuse it.
“Magnesium and sulfur are building blocks for plants,” said Hill, the Epsom Salt Council’s president. “We think you’ll see a real difference.”
