Coffee grounds are a nutrient-rich fertilizer that improves soil structure and promotes plant growth. However, not every plant benefits from coffee grounds as fertilizer.
Coffee grounds are very suitable as a natural fertilizer for the garden because they are rich in nutrients such as nitrogen, phosphorus and potassium, which promote plant growth.
The nutrients in coffee grounds support soil fertility and help balance the soil’s pH.
In addition, coffee grounds act as organic material that improves soil structure and increases water storage. By composting coffee grounds or sprinkling them directly onto the soil, you can contribute to improving soil quality in a simple and sustainable way.
Do not use coffee grounds with all plants
Some plants may die if you fertilize them with coffee grounds.
While coffee grounds can be very good for some plants, not all plants like the high concentration of caffeine and acids they contain.
This means that coffee grounds are only suitable for plants that need acidic soil to thrive.
In particular, some types of ornamental plants such as asters or Christmas roses can be stressed or not develop well due to the acidic nature of coffee grounds.
An overdose of coffee grounds can also affect the growth of vegetable plants such as carrots and celery.
