How to Use Epson Salts in My Garden


Epsom salt is a non-toxic substance with many purposes. Epsom salt is typically used for sore muscles and healing wounds, but according to the Epsom Salt Council, it is also useful in the garden. The council states that Epsom salt contains many useful nutrients for gardening. Specifically it states that "although magnesium and sulfur occur naturally in soil, they can be depleted by various conditions, including heavy agricultural use over time. But unlike most commercial fertilizers, which build up in the soil over time, Epsom Salt is not persistent so you can't overuse it. Tests by the National Gardening Association confirm--roses fertilized with Epsom Salt grow bushier and produce more flowers, while the compound makes pepper plants grow larger than those treated with commercial fertilizer alone."

Rose Food

Warm up the distilled water in the microwave for 10 minutes on high.

Step 3

Add the coffee grounds and allow the mixture to sit overnight.
