The most common way to fertilize a Missouri Evening Primrose is to apply a granular or pellet fertilizer to the soil around your plant. Remember that the ideal time to fertilize is as the plant is exiting its winter dormant growth phase and entering a phase of active growth. In early spring, wait until the plant begins to send shoots through the soil, and then apply your fertilizer. Some people may choose to use a liquid fertilizer instead of a granular one. In that case, you should dilute the fertilizer with water before applying it. Regardless of whether you use granular or liquid fertilizer, it is always best to moisten the soil before, during, and after you apply fertilizer.
