How to Grow Chinese Evergreen (Rohdea japonica): With the Right Methods, Its Leaves Stay Deep Green All Year Round

Rohdea japonica (Chinese evergreen) is a perennial evergreen herbaceous plant in the Asparagaceae family, with broad, upright leaves that stay deep green year-round and red berries that persist through winter, giving it a very long ornamental season. It prefers a warm, humid, semi-shaded environment, tolerates shade well, and is easy to manage. It is commonly grown in pots and placed in living rooms and studies, and is also suitable for planting in shaded spots in courtyards. Similar foliage plants often found on the market include Dieffenbachia and Aglaonema, which have similar habits, so their care methods can be used as reference for one another.

In terms of light and temperature, Rohdea japonica dislikes strong direct sunlight; indoors, placing it in bright indirect light is enough, and in summer it should be shaded appropriately to prevent the leaf tips from scorching. It likes a warm environment, so take care to protect it from the cold in winter, keeping it above 5 degrees and avoiding direct cold drafts; during cold periods, watering should also be reduced.

For watering, follow the principle of watering when dry and letting it dry out between waterings: wait until the surface of the potting soil is dry, then water thoroughly. Never let water accumulate for long periods, or the roots may rot and the leaves turn yellow. During the peak growing seasons of spring and autumn, keep the potting soil moist, and when the weather is dry, mist the leaves to increase humidity. For soil, choose a loose, fertile, well-drained, slightly acidic sandy soil; a mix of leaf mold, garden soil, and river sand works well.

During the growing season, apply a dilute liquid fertilizer about once every half month, applying little but often. Gradually reduce feeding after late autumn, and stop fertilizing in winter. Propagation is mainly by division, usually done when repotting in spring: cut off the small offsets growing beside the mother plant together with their roots and plant them separately, and they will survive.

In daily care, if yellow leaves appear, it is usually related to direct sun, waterlogged soil, or a lack of fertilizer; once you find the cause and adjust accordingly, the plant will recover. Note that the sap and berries of Rohdea japonica are toxic, so it is best to wear gloves when pruning, and place the plant where children and pets cannot easily reach it to avoid accidental ingestion.
