Phosphorus is an essential nutrient when growing plants in any number of landscape soils. The nutrient is unique in that it helps plants produce vivid colours and promotes root, seed and fruit growth, in addition to helping plants ward off diseases. There are several brands of high phosphorous or super phosphorous fertiliser available today at most gardening stores and nurseries.
