One-fifth of coffee and other waste is an excellent start to the compost mixture. It is also possible to include a small quantity of waste from plants (leaves or sticks). Mix it in once every two months, and observe how the plant reacts.

Be careful not to make the compost too moist and muddy. The compost is likely to hold water, so make it an effort not to drown the plant in this way.

Use Coffee Grounds as Liquid Fertilizer

Making fertilizer using coffee grounds is simple. Fill the vessel with water and then add the coffee grounds, and allow it to draw for a week or so.

If youd want to, stir the mixture every few days. After 2 weeks, once the coffee grounds begin to break down then, strain the water and feed it to your plants.
