Plants that have been fertilized with almost anything will appear great to plants that receive little or no fertilizer. Triple-20 gives you blanket coverage on all the major nutrients. However, different plant families and plants from different ecosystems have different capacities and needs for nutrients. Plants native to western Australia do not tolerate phosphate well. Many species of Vaccinium are sensitive to
Urea Nitrate Nitrogen. Many subtropical fruits such as citrus will ignore excess potash (i.e., you are wasting it). For a general guide to needs of edible plants, see:
