What are the propagation methods for Rohdea japonica? This article explains in detail
Rohdea japonica is a common ornamental plant that prefers high temperature, high humidity, and semi-shaded or fully shaded environments. It is not cold-tolerant, dislikes direct strong light, and requires loose, fertile, well-drained sandy loam soil. Its propagation methods mainly include division, cuttings, and seed sowing. Let's take a look at the propagation methods of Rohdea japonica!
Division propagation of Rohdea japonica
Division propagation of Rohdea japonica is usually carried out in spring when repotting. The plant is lifted out of the pot, the rhizome at the base of the stem is cut off, and wood ash is applied to prevent rot, or it is left for half a day until the cut surface dries before being potted. After planting, watering should not be excessive. For natural offset propagation, the bulbs are dug up in August-September and planted according to size grades. After one planting, division is carried out again several years later when the bulbs become crowded.
Cutting propagation of Rohdea japonica
Cutting propagation of Rohdea japonica is best done in spring and summer. Select sturdy young stems 12-15 cm long as cuttings, keep the top 2 leaves, and insert them into a sand bed. Maintain high air humidity at a room temperature of 25-30°C. Roots form 20-28 days after insertion. Water propagation can also be used, with slightly longer cuttings, preferably 15-20 cm. Insert them directly into a glass bottle filled with clean water, change the water once every 2 days, and new roots will grow in about 15-20 days. When the roots are 3-4 cm long, pot them up.
Seed propagation of Rohdea japonica
Seed propagation of Rohdea japonica is generally carried out between March and April. Sow in a flower pot filled with culture soil, water, and temporarily place in a shaded spot, keeping it moist. At 25-30°C, germination occurs in about 25 days.
