What are the best type fertilizers to use?
A complete fertilizer is best for most plants. A complete fertilizer means that all three major elements – nitrogen, phosphorous, and potassium – are available in that fertilizer in some proportion. It is also recommended that a fertilizer containing other elements such as iron, manganese, sulfur, etc. be applied once a year. These nutrients are listed on the label as secondary and/or minor plant nutrients. For a “long lasting” fertilization select a fertilizer containing some percent “Water Insoluble Nitrogen”.
