Almost everyone has heard of using coffee grounds to fertilize plants. But how good is it, how effective is it, or what are the limitations of using coffee grounds as plant fertilizer, not everyone knows.
Luckily, you don’t need to spend too much time researching these facts as they have all been summarized in this article. However, the following reminders will help you use coffee grounds more effectively in caring for indoor plants.
1. Are coffee grounds good for indoor plants?
It’s difficult to give an accurate answer to this question. Studies have shown that coffee grounds contain beneficial nutrients for plant growth but also contain substances that can inhibit the growth of some indoor plants.
In addition, the effect of coffee grounds on different types of plants will depend on how you use them. It is best to indirectly fertilize your plants to avoid creating mold that can harm them.
2. Benefits of coffee grounds for plants
After being used, coffee grounds still contain a mixture of proteins, oils, and carbohydrates that water cannot extract. Coffee grounds also contain potassium and small amounts of phosphorus, as well as trace elements beneficial to plants such as calcium, iron, zinc, and magnesium. Therefore, it can be seen that used coffee grounds contain many nutrients that are beneficial for plants.
Although they contain many nutrients, plants cannot directly utilize those nutrients. Coffee grounds need to be composted to break down the nutrients. Through this process, soil bacteria will transform the nutrients in coffee grounds into compounds that plants can use. Composted coffee grounds also contribute organic matter to the soil, improving its structure.
Some studies have also shown that used coffee grounds can inhibit certain plant pathogens.
3. Limitations of using coffee grounds for plants
In addition to the aforementioned benefits, using coffee grounds for plants also has some disadvantages. Coffee grounds contain caffeine, which can hinder plant growth if directly applied.
4. Best practices for using coffee grounds for plants
The best way to use used coffee grounds for plants is to compost them to break down the nutrients. Then, you can mix this natural fertilizer with the soil for planting. Doing so will not only stimulate plant growth but also effectively improve the quality of the soil.
