The increase in coffee consumption does cause questions on how grounds are disposed of by coffee shops or by households every day.
Recycle your used coffee grounds as fertilizer for your plants.
Simply sprinkle some used coffee grounds onto the soil surrounding your plants.
Depending on how you utilize them within the right conditions, the grounds enhance the soil, or to make a pest-controlling mulch could also be good for plants.
The advantage of using the grounds as fertilizer is that it adds organic material to the soil, which improves drainage, water retention, and aeration within the soil. They contain several key nutrients required for plant growth, as well as attracting worms and reducing the concentrations of heavy metals within the soil.
Will coffee grounds acidify your soil?
The acid in coffee beans is water-soluble. So, it’s in your cup of coffee, not the used grounds that's being acidic. The grounds are pH of 6.5 to 6.8 which is pH neutral.
Before you begin adding the grounds to your soil, you would want to test your soil with a simple pH test kit to ascertain more or fewer grounds to your compost or mulch what it actually needs.
Using them as mulch directly on your soil can inhibit water retention and air circulation, and have a negative effect on plant germination and early growth. But the indirect use of them can have just the other effect.
There is the 20% rule: Apply one part of grounds to four parts of other organic material.
