Colorburst plant food features slow-release pellets that contain at least 15 percent nitrogen, 30 percent phosphorous and 15 percent potassium. These elements are often lacking in ground soil, and flowering plants need them to mature.
To apply Colorburst plant food, gardeners need to distribute the pellet mixture in the soil around flowering plants. Gardeners can apply the granule mixture every two months throughout the year as needed. The manufacturer recommends mixing this product into the soil before introducing new flowering plants.
Gardeners should not use Colorburst plant food as vegetable or herb fertilizer. This product does not dissolve in water. Colorburst offers a money-back guarantee if this plant food does not meet a gardener's expectations.
Gardeners can purchase a 3.5-lb. bag of Colorburst plant food for under $6.00, as of April 2011.
