I usually feed my roses at the same time I feed the rest of my perennials and garden, but this Epsom salt fertilizer idea has me intrigued.
Serious Rose enthusiasts use Epsom salts to help strengthen their plants. Using Epsom salt helps “build” lush, dark green foliage as a gorgeous backdrop to dazzling, bright, abundant blooms. The added magnesium levels help increase the production of chlorophyll in the plant for strength and deep, rich color.
If the soil becomes depleted of magnesium, adding Epsom salt will help; and since it poses little danger of overuse like most commercial fertilizers, you can use it safely on nearly all your garden plants.
Epsom salts are inexpensive and easy to use. So I'm going to give this a try, and I'll post another blog in a few weeks to update on how my Epsom Sat Rose Fertilizer experiment has been going.
