Epsom Salt as Plant Food

entry from the Tacoma News Tribune 'Get Growing' blog

Alert! This just in from the Epsom Salt Council. Could it possibly be true?

Just as “Milk does a body good,” Epsom Salt may be one of the most perfect nutrients for flowers and plants. And mid-to-late spring is the ideal time to nourish the soils and roots of your favorite foliage and flowers with this inexpensive and easy-to-use compound. According to the Epsom Salt Council, research indicates Epsom Salt can help seeds germinate; make plants grow bushier; produce more flowers; increase chlorophyll production; improve phosphorus and nitrogen uptake; and deter pests, including slugs and voles.

Anyone used Epsom salt? What did you think? If you haven't tried it, but want to, the Epsom Salt Council recommends these amounts:

Shrubs (evergreens, azaleas, rhododendron): 1 tablespoon per 9 square feet. Apply over root zone every 2-4 weeks.

Lawns: Apply 3 pounds for every 1,250 square feet with a spreader, or dilute in water and apply with a sprayer.

Trees: Apply 2 tablespoons per 9 square feet. Apply over the root zone 3 times annually.

Garden Startup: Sprinkle 1 cup per 100 square feet. Mix into soil before planting.

Roses & Tomatoes: Use 1 tablespoon per foot of plant height per plant; apply every two weeks.
