Rose bushes are beautiful plants that produce dozens of fragrant blooms everyone can enjoy. But did you know that an easy, cheap way to grow more fruitful rose bushes is through coffee grounds?
After you grind coffee beans for use, the leftover coffee grounds make a great organic fertilizer that is cheap and easy to get your hands on, assuming you’re a coffee drinker.
How to Make Coffee Fertilizer
There are several methods for using the coffee grounds to fertilize your rose bushes.
One way is to just put the coffee grinds in a compost heap with other waste from your kitchen, sprinkling the mixture around the roses.
Another method is to just sprinkle plain, dried up grounds at the base of your roses.
Additionally, you can mix 3 parts coffee grounds with 1 part wood ash to mix into the soil around the plants.
Finally, you can mix about a 1/2 pound of used grounds with 5 gallons of water for a mixture you can pour on the rose bushes about twice a month.
Why is Coffee Grinds Good for Rose Bushes?
The reason coffee grinds are so good for rose bushes is that of their high nitrogen content. Roses need neutral to acidic soil, and if you add coffee grinds, it will help take the pH from neutral to acidic.
Coffee grinds also help loosen the soil, which gives the roots more space to grow and helps deliver the nutrients they need to survive.
