Where is the plant? Inside/outside? Containerized/Ground? High nitrogen (first number should be highest). Some might add dried blood meal to an outdoor bed (which is high in nitrogen). Read the label for frequency. For max growth, make sure you keep up with expanding size by transplanting (if containerized). Use a rich soil (high in humus), avoid prepackaged soils that are essentially sterile peat moss. They are cold hardy in the ground to probably Zone 6 (especially with protection). Otherwise, they are easy plants.
