Fatsia Japonica does best with warm, humid summers alternating with a relatively cooler, drier period. However, it will die in very cold, drafty, dry conditions. It is relatively easy to grow indoors if you follow these guidelines
Light: This is a marginal plant, meaning it grows best in partial shade or even full shade. The plant will bleach out in full sunlight, so a few hours of morning sun in an eastern exposure are best, or indirect light.
Water: During the growing season, regular moisture is essential. During the winter, cut back water slightly. They are sensitive to sitting in water, so good drainage is impotant.
