Coffee, the secret of a beautiful garden. It will also help you get gorgeous hydrangeas!

Using coffee grounds can bring many benefits to your garden. It promotes healthy plant development, repels unwanted insects, and even produces gorgeous blue hydrangeas. Here's how you can use it!

Ground coffee can be used as a natural fertilizer as it contains nitrogen, magnesium and potassium, important nutrients for plant growth and development. "Coffee grounds are a great addition to compost because they're high in nitrogen, which is a key ingredient for plant growth," Los Angeles-based Chia-Ming, who advises adding coffee grounds to your regular compost, explains to Reader's Digest. Also for balanced soil, he also recommends using eggshells. Read here how they help you have beautiful and healthy plants!

Advice: For plant growth and development, mix some coffee grounds with warm water, pour the liquid into a container, spray the solution onto the soil, and mix the soil well. This trick works for both garden and potted plants.

Gets rid of unwanted insects

Want to get rid of unwanted insects in your garden? Use coffee grounds, which repel certain insects such as ants, slugs and mosquitoes: "This may be due to the strong aroma of coffee, which masks the smell of the plant and may make it less attractive to insects," the expert notes. To use it, all you have to do is sprinkle coffee grounds at the base of the plants or where there are bugs.

This will help you get the blue hydrangeas you want.

If you want your blue hydrangeas to have such a beautiful color, coffee grounds will help you, because they have a neutral pH. “The color of many types of hydrangeas is dictated by the pH of the soil,” says the specialist. All you need to do is apply coffee grounds to the soil at the base of the hydrangea. Also keep in mind that you need to purchase species that are known to produce flowers of that color.

Advice: It is important not to exaggerate the amount of coffee used, as coffee can damage plants!
