How to Fertilize roses with coffee grounds
The Sun Sprite Rose has a nice fragrance but you want to keep it healthy by fertilizing it. Roses are heavy feeders so Charlie suggests adding compost in the Spring, really building up the soil, maybe put in some time release fertilizer pellets, then use regular Rose food to keep the Roses really looking good. Another home remedy involves fertilizing with coffee grounds. Coffee grounds sprinkled around Roses about a quarter of an inch to half an inch thick will help Roses grow and bloom better. So after you perk your coffee, save the grounds, dry them out, then sprinkle them around. You'll find your Roses perform better.
