Definition: Kelp meal is a very high-quality organic fertilizer. With an N-P-K ratio of approximately 1-0-2, it is a good source of nitrogen and potassium. It also contains minerals, amino acids, and trace amounts of other micronutrients. Kelp meal is seaweed, specifically Ascophyllus nodosum, and is harvested from the ocean. It can be added to vegetable and flower gardens, potting mixes, and lawns. Apply kelp meal at a rate of one pound per 100 square feet in spring (for annual plantings) or fall (for perennials).
