Can I Water My Plants With Coffee?

Many gardeners today are looking for natural alternatives to traditional garden care. One popular method is to use coffee to water plants. But, can you actually water your plants with coffee? The answer is yes, but with a few caveats.

Benefits of Using Coffee as Plant Fertilizer

Coffee is an excellent source of nitrogen, phosphorus, and potassium – all essential nutrients for healthy plant growth. By mixing coffee grounds with water, you can create a natural fertilizer that provides these nutrients to your plants.

In addition, coffee helps to make soil more porous, enabling water to penetrate more effectively. This will help make sure that your plants get watered properly and evenly.

Cautions of Using Coffee to Water Plants

It’s important to be aware of the potential drawbacks of using coffee for plant care. Coffee grounds can make soil too acidic for some plants, so it’s best to test soil pH levels before using coffee grounds.

You should also be careful not to use too much coffee, as this can cause nutrient imbalances in the soil. For best results, use one part coffee grounds to three parts water.

Other Uses for Coffee in Gardening

In addition to being a great source of nutrients for your plants, coffee grounds can also be used to:

  • Repel pests: Coffee grounds can help keep away certain small pests, such as ants, slugs, and snails.
  • Add organic matter: Coffee grounds can be added to compost to improve organic soil content.
  • Keep cats away: Sprinkling used coffee grounds around your garden can help to deter cats from digging in the dirt.


It is possible to water your plants with coffee, however there are precautions that should be taken. Coffee is a great source of nitrogen, phosphorus, and potassium, and can be used to help deter pests and improve soil quality. Just be sure to use in moderation and test pH levels first.
