How to keep Mahonia Japonica.
Light
Japanese mahonia grows best in sites that receive a steady, moderate amount of sunlight during the day. Too much light can cause leaf scorch, while too little light often leads to weak growth. In its native habitat, this plant experiences consistently moderate sun.
Temperature
Japanese mahonia naturally occurs in areas where temperatures range from 59 to 89.6 °F (15 to 32 ℃). These temperature preferences mirror the plant's native habitat, indicating it should be maintained within that range to thrive. In colder or hotter seasons, consider adjusting the temperature to accommodate its needs.
Fertilizer
Timing is essential when fertilizing Japanese mahonia. Apply fertilizer in early spring and repeat monthly until early summer. Fertilizer promotes lovely blooms and supplies energy during both dormant and active growth periods.
