Many gardeners enjoy searching for new and innovative ways to improve their gardens naturally without the use of chemicals and synthetic products. Often a gardener must only look as far as his kitchen to find effective materials for fertilizing a garden. Use a banana peel as plant food to nourish your plants naturally. Because bananas contain potassium, these nutrient-dense fruit peels will help nourish plants as they break down in the soil of your growing areas.
Place the banana peels onto the cutting board, and coarsely chop them into 1-inch pieces with the utility knife. Gather the chopped banana peels in the bowl or bag, and carry them out to the garden.
Dig a small trench around your plants with the trowel, spacing the trench approximately 6 inches away from the plants. Make the trench about 2 inches deep.
Sprinkle the chopped banana peels evenly around the prepared trench in a single layer.
Cover the banana peels with soil, and pat the soil down firmly over the banana peels.
Water the soil area around the plants generously to help the banana peels begin to disintegrate in the soil.
