Product Description J Arthur Bower's Multi-Purpose Compost contains nitrogen (N) for green leaf and shoot growth, phosphate (P) for strong root development and potassium (K) for more flowers and fruit. It also contains trace elements to promote plant health and disease resistance. It can be used for virtually all types of plant and the slightly coarse texture is perfect for all you potting needs as it promotes healthy root growth and resists compaction. J Arthur Bower's Multi-Purpose Compost will provide your plants with all the nutrients they need for a strong healthy growth during the first 4-6 weeks. After that, feed them every 7-14 days during the growth season with one of the J Arthur Bower's plant foods.
