Fatsia Japonica

Fatsia japonica (commonly known as Japanese Aralia) is a striking, evergreen shrub known for its large, glossy, and deeply lobed leaves. It’s a popular choice for both indoor and outdoor gardens due to its attractive foliage and relatively low-maintenance nature. Here’s a detailed care sheet to help your Fatsia japonica thrive.

Light

  • Bright, indirect light is ideal for Fatsia japonica. It can tolerate lower light levels, but its growth may slow down, and the leaves may lose some of their vibrancy.

  • Fatsia can grow well in areas with light filtered through curtains or in partially shaded spots.

Temperature

  • Optimal Temperature: 60°F to 75°F. It thrives in warm environments but can also tolerate slightly cooler temperatures.

  • Cold Sensitivity: Fatsia japonica is sensitive to frost and should be kept in temperatures above 50°F. It can tolerate brief cold spells, but prolonged exposure to cold can damage the plant.

  • For indoor plants, keep them away from drafts, air conditioners, or heaters.

Watering

  • Water when the top 1-2 inches of soil feels dry. Be sure not to overwater, as Fatsia prefers slightly moist soil but does not like to sit in standing water.

  • Water deeply when you do water, but ensure the pot has good drainage to avoid waterlogging and root rot.

  • In winter, reduce watering frequency as the plant's growth slows down.

Fertilization

  • During the growing season (spring and summer), feed Fatsia japonica once every 4-6 weeks with a balanced, water-soluble fertilizer.

  • In fall and winter, reduce fertilization as the plant’s growth slows down. Avoid fertilizing during the dormant period to prevent overfeeding.

  • If the leaves start to yellow, a mild dose of fertilizer can help, especially if nutrient deficiencies are suspected.

Growing Tips

  • Support for Larger Plants: Fatsia japonica can grow quite tall (up to 6-10 feet in ideal outdoor conditions). If growing it indoors and you want to manage its size, regular pruning will help.

  • Outdoor Care: In USDA hardiness zones 8-10, Fatsia can be grown outdoors as an evergreen shrub or small tree. If grown outdoors in colder regions, protect it from frost by bringing it indoors or covering it in winter.
