Are Coffee Grounds Good for Azaleas?

Azaleas are popular flowering shrubs prized for their brightly colored blooms. While these plants often thrive in acidic soil and can benefit from certain acidic amendments, there is some dispute as to whether coffee grounds are an ideal source of those nutrients.

The Benefit of Coffee Grounds on Azaleas

Coffee grounds are a naturally acidic amendment, making them popular among gardeners looking to improve the soil quality of acidic plants. Because they are rich in nitrogen, they can improve the fertility of the soil, which is important to the success of any plant.

The Potential Risks

However, because coffee grounds are high in nitrogen, they can throw off the pH balance of your soil if you use too much, making it too acidic. Additionally, they can attract creatures like cats, racoons and skunks that may damage the plants.

The Bottom Line

In conclusion, coffee grounds can be beneficial to an azalea garden when used in moderation. Keep in mind that too much of this amendment may lead to an overly acidic soil that could be harmful to the plants. It’s also important to secure the grounds properly to avoid attracting unwanted animals.

Tips for Using Coffee Grounds:

  • Use them sparingly; no more than a quarter of a pound per plant.
  • Mix them into the soil to help diminish their potent smell.
  • Make sure the grounds are completely dry before adding them to the soil.
  • Only use grounds from caffeinated coffee; decaf doesn’t have the same nutrients.
  • Tilling the soil prior to adding the grounds helps to spread the nitrogen more evenly.
