cutting

(1) Time: Osmunda japonica Thunb. had better be cut in July-August every year, because at this time, the new branches grow most vigorously and the survival rate is the highest.

(2) Method: Semi-lignified branches with a length of about 8- 10 cm and a cutting depth of about 3-4 cm should be selected for Osmunda japonica cutting, then watered once and shaded later.

Sowing propagation

(1) Time: Osmunda japonica is usually sown and propagated in March and April in spring, when the climate is most suitable.

(2) Method: Osmunda japonica. Seedbed should be prepared before sowing, preferably in transparent, soft and fertile soil. After sowing, the seeds can be properly covered with some fine soil, so that they can take root and sprout in about 1 1 day, and intertillage weeding should be done well in the later stage.

Stratified propagation

(1) Time: Osmunda japonica is propagated by layering, and there is no time limit. It can be carried out all year round, but it is best to carry out it around March.

(2) Method: Select 2-year-old robust branches, tie them around 2 cm, apply some rooting powder on the wound, wrap it with a layer of wet soil after the wound is dry, and tie both ends with plastic film to wait for rooting.
