What plants can you water with coffee?

Coffee is a popular beverage all over the world, and many coffee lovers are always looking for ways to reuse their coffee grounds. One way to use coffee grounds is by adding them to a compost bin, but did you know that coffee can also be used as a fertilizer for plants? In this article, we will explore what plants can be watered with coffee and how to do it.

Plants that love coffee

Coffee grounds contain nitrogen, potassium, and phosphorus, which are essential nutrients that plants need to grow. Therefore, plants that love slightly acidic soil, such as azaleas, rhododendrons, and camellias, can benefit from being watered with coffee. Other acid-loving plants that can benefit from coffee include blueberries, cranberries, and roses.

In addition, coffee can also help repel some pests that can damage plants. The caffeine in coffee can deter slugs, snails, and other insects from eating your plants. Therefore, plants that are prone to pest infestations, such as tomatoes, peppers, and spinach, can also benefit from being watered with coffee.

How to water plants with coffee

Before you use coffee as a fertilizer for plants, it is important to note that not all plants can tolerate coffee. Plants that are sensitive to acidic soil, such as succulents and some herbs like basil, should not be watered with coffee. In addition, plants that need well-draining soil, such as cacti, should not be watered with coffee either.

To make coffee fertilizer for your plants, you can use either brewed coffee or coffee grounds. If you are using brewed coffee, let it cool before adding it to your plant's soil. For coffee grounds, mix them with soil before applying them to your plants. Be sure to mix the grounds thoroughly with the soil to avoid clumps that could cause root burn. The coffee grounds can also be added to your compost bin.

If you choose to water your plants with coffee, it is best to do it in moderation. Too much coffee can increase the acidity of the soil, which can harm your plants over time. Therefore, it is recommended to water acid-loving plants with coffee once a week or so.

Conclusion

In conclusion, coffee can be a great fertilizer for plants that love slightly acidic soil and can help repel some pests. However, it's important to note that not all plants can tolerate coffee, so it's best to check before using it as a fertilizer. Always use coffee in moderation and mix the grounds with the soil to avoid clumps. With proper use, coffee can be a great addition to your plant care routine.
