Are coffee grounds good for roses?


For avid flower gardening enthusiast, the use of coffee grounds as fertilizer offers many advantages, especially when it comes to growing beautiful and healthy roses.

Coffee grounds are a great source of nitrogen, potassium, phosphorus, and copper, all essential nutrients needed by roses in order to thrive.

The application of this natural fertilizer also provides some added benefits that will help enhance the overall health and beauty of your rose garden.


Nitrogen is an important nutrient that helps promote healthy growth and blooming in your rose bush because it aids in the stem and leaf development.

It is one of the three primary macronutrients essential for healthy plant growth along with phosphorus and potassium.

When nitrogen is present in adequate amounts in the soil, it helps create stronger stems that can support more flowers.

Potassium, Phosphorus, & Copper

Potassium, phosphorus, and copper are all vital elements that are needed by roses in order to grow properly.

These three elements help build strong cell walls which give the stems strength and rigidity that allows them to support more flowers.

Coffee grounds also provide an extra boost of these essential nutrients which can give your rose bush a much needed nutrient boost.

Fertilizer Application

When applying coffee grounds as fertilizer for your rose bush it is important to keep in mind that too much can be detrimental to their growth.

It is best to mix the grounds into the soil at a rate of one part ground per five parts soil.

It is also recommended that you apply the mixture once every two weeks during active growing periods such as springtime when blooms are forming.

Pest Control

Coffee grounds can also be used as a form of natural pest control if your roses become infested with aphids or other pests.

Simply sprinkle some ground around the base of your rose bush or spray some directly onto affected areas where pests may be present.

The acidic nature of the grounds will help naturally repel pests while also fertilizing your plants at the same time!

Composting with Coffee Grounds

Composting with coffee grounds has many benefits when it comes to nourishing soil for roses.

The nitrogen content helps improve soil structure while helping break down organic matter making it easier for plants to absorb essential nutrients from the soil.
