Used Coffee Grounds
Many items we usually throw away can help your plants thrive and used coffee grounds are a great example. Instead of throwing them away, rinse them and use them to fertilize the soil by sprinkling them on top. Using them without rinsing is also an option and it will give the soil an acidic boost.
Coffee grounds will help fight all sorts of pests and they attract earthworms. Earthworms won’t damage your plants and they aid fertilization by feeding on decaying plant material.
