Instead of buying a $25 bag of fertilizer from the garden store, make your own using kitchen scraps. Blend together cut up pieces of banana peels, egg shells, and coffee grounds. Then place the mixture near the roots of your plants.
How does it work? As banana peels biodegrade, they release potassium, nitrogen, phosphorus, and magnesium into the soil. Banana peels are also known to repel aphids. Coffee grounds are an excellent source of nitrogen, which your plants love. Adding crushed egg shells to the mix will provide calcium to your soil to help build the plants' cell walls. Crushed shells also deter slugs and snails from coming into your garden because they don't like climbing over the sharp shell shards.
