This article will provide a detailed introduction to the cultivation of Fatsia japonica, including key aspects such as soil, light, watering, and fertilizing to help you grow a healthy and beautiful plant.
Soil SelectionFatsia japonica thrives in fertile, well-draining soil. You can choose a growing medium made from a mixture of peat, leaf mold, and perlite. The soil pH should be slightly acidic to neutral, with an optimal range of 5.5-6.5.
Light RequirementsFatsia japonica prefers a semi-shaded environment and does not tolerate prolonged direct sunlight.

In winter, when temperatures are lower, reduce watering to prevent root rot. When watering, be careful to avoid splashing water on the leaves to prevent leaf rot.
Fertilizing TechniquesFatsia japonica does not require heavy feeding. Applying a compound fertilizer once a month during the growing season is sufficient. Choose a fertilizer with an appropriate balance of nitrogen, phosphorus, and potassium to promote plant growth. After fertilizing, water immediately to dilute the fertilizer and prevent root burn.
