Does Gardenia Like Coffee Grounds?

For many gardeners, coffee grounds are seen as a great amendment to the soil in their beds. But what about gardenias? Can they benefit from coffee grounds’ residual nutrients?

The Answer

The answer is a resounding yes! Coffee grounds are a wonderful way to give gardenias some additional help. Here are some of the benefits they provide:

  • Acidity: Gardenias need acidic soil, and adding coffee grounds can increase the acidity of the soil, giving them the environment they need to thrive.
  • Nutrients: Coffee grounds are an excellent source of nitrogen, potassium and other minerals, which can help your gardenias to flourish.
  • Mulch: Coffee grounds can be used as a great mulch material, helping to keep the soil moist and weed-free.

How to Use Coffee Grounds for Gardenias

To reap the benefits of coffee grounds for your gardenias, you’ll want to follow a few simple steps:

  • Start by gathering some used coffee grounds – the fresher, the better. If you don’t have access to fresh coffee grounds, you can purchase them at many gardening stores.
  • Mix the grounds into your soil. You’ll want to mix them in thoroughly, as they can be too concentrated when used directly around a single plant.
  • If you are using them as a mulch material, simply spread them on top of the soil and use a rake to evenly distribute them.
  • Finally, give your gardenia a thorough watering, ensuring that the coffee grounds are properly soaked into the soil.


Coffee grounds can be a great way to give an extra boost to your gardenia plants. Careful use of these grounds can provide the acidic environment and additional nutrients these plants crave – leading to a more vibrant and beautiful garden!
