If you\u2019re a coffee-loving gardener, you probably know about the hype surrounding coffee grounds and their potential uses on plants. Whether you brew your own cup every morning or your local coffee shop gives out used grounds for free, you could be wondering if this organic material is healthy for your plants.<\/p>\n
Can you use coffee grounds as fertilizer? Are they harmful to some plants, and which plants are they good for? Let\u2019s see how you can put your used coffee grounds to work!<\/p>\n
For optimal plant growth, we need to add essential nutrients to the soil. Over time, the growth of your plants depletes the natural nutrients found in the soil. That\u2019s why it\u2019s recommended to fertilize the soil frequently. Moreover, if you buy commercial fertilizers, they will provide your soil with macro-nutrients, such as potassium, phosphorus, and nitrogen<\/a>.<\/p>\n However, coffee grounds, or the ground coffee beans that are left behind in a coffee pot, contain a lot of those nutrients. Plus, they are full of magnesium, iron, chromium, and calcium. Introducing them to your soil can improve the health of your garden or container plants. Additionally, it\u2019s a useful option for recycling coffee grounds.<\/p>\n Fresh or used coffee grounds are an organic substance. They can fertilize plants, improve the quality of soil, and help you deter pests. Still, to reap their full benefits, you should know when to use them and when to avoid them. Here\u2019s what coffee grounds can do for your plants:<\/p>\n While using coffee grounds as fertilizer can produce lush leafy growth, research shows that they can harm your plants if used incorrectly. For example, they can create a solid barrier over your soil. What\u2019s more, they can dry out your plants.<\/p>\n Also, caffeine could hinder seedling growth. If you use fresh coffee grounds, you can increase the acid content and lower the pH in the soil. In theory, this is beneficial to acid-loving plants, such as azaleas or blueberries. Yet, the acid in the grounds is soluble and will break down once you water your plants. So how can you reap the benefits of coffee grounds for your plants while avoiding some of the drawbacks?<\/p>\n Any lover of filtered coffee will ultimately throw away a lot of used grounds on a daily basis. If you want to reuse your morning coffee grounds on your plants, you can do so in several ways.<\/p>\n You can compost old grounds and paper coffee filters. This is as simple as adding the coffee grounds and filters to your compost bin. The grounds are helpful because they will increase the nitrogen content in the compost pile.<\/p>\n Furthermore, coffee grounds are a green compost material. Hence, you will need to add other brown compost materials to balance your pile. Generally, the safest way to do this is to have a four-to-one ratio of brown and green compost material.<\/p>\n The most common method is to simply add the coffee grounds on top of the soil. Then, they will act as a slow-release fertilizer. This will boost organic matter in the soil. As mentioned, coffee grounds contain macro and micronutrients that improve soil structure. What\u2019s more, used coffee grounds have a neutral pH, meaning that you shouldn\u2019t be concerned about acidity.<\/p>\n To use your coffee grounds, simply sprinkle them on top of the soil. Then, they will increase the nitrogen content. However, you should avoid piling up the grounds. If you have too many coffee grounds on your soil, you\u2019ll create a water-resistant barrier. Another tip is to mix them with water. You could put two cups of coffee grounds into a bucket with five gallons of water. Then, you\u2019ll end up with an effective liquid fertilizer for container and garden plants.<\/p>\n Another way to use coffee grounds for plants is to invest in a composting vertical garden planter. You can use coffee grounds with Garden Tower 2<\/a>, a garden planter that accommodates up to 50 plants. This container garden allows you to load compostable materials such as coffee grounds into a vermicompost tube or a two-gallon drawer. Alternatively, you can put coffee beans directly onto the soil in the opening pockets of Garden Tower 2 to give your plants a healthier diet without harmful chemicals.<\/p>\nBenefits of Coffee Grounds<\/h2>\n
