In nature, these plants grow in shaded to partially shaded areas. It is important that you don’t give your fatsia too much direct sun. In most locations indoors, an eastern exposure window would work very well for these plants. This is not a plant to place in the sunniest window that you have; otherwise, the foliage will burn. Be sure to provide this plant with good moisture levels. Never let this plant completely dry out. At the same time, you don’t want this plant to sit in water either. You may want to reduce watering a bit in the winter as growth slows down or comes to a halt. Fertilize regularly with an all-purpose fertilizer throughout the growing season. Reduce to eliminate fertilizer during the winter months depending on if the plant has slowed down growth or completely stopped. Resume again in the spring when new growth starts again. These plants grow best if you can provide warmer conditions throughout the growing season, but cooler (not cold) conditions of 10-15 C during the wintertime. Be careful not to place this plant in any area indoors that has cold drafts. If you live in a cold climate, don’t place this plant near any doors where it might receive drafts. These plants can get quite tall, so don’t be afraid to cut your plant back.
