Providing your plants with the proper nutrition will help to keep them in optimum health, and enable them to fight off disease and pest attacks. Fertilizers often have three numbers on the packaging, indicating the proportions of nitrogen, phosphorus and potassium, three elements essential for plant growth and health. These simple organic formulas can easily replace chemical fertilizers and offer the bonus of adding trace elements and improving your soil. Organic fertilizers won’t ‘burn” your plants, and are naturally slow-release, feeding your soil and plants for months.

Lawn fertilizers

Lawns will benefit from applications of sifted compost, or any of the nitrogen sources listed above. Another organic lawn fertilizer to try is corn gluten meal, which fertilizes the grass while suppressing weed seed germination!
