a) Propagation by layering
Propagation by layering is good because a new plant can bloom in the year of planting. A branch of an adult flower is slightly cut, covered with moistened moss, and covered with a polyethylene film.
After the appearance of the roots, this branch is cut off and transplanted into a separate pot. You can immediately put such a branch in a new container, fix it with moss, and then cut off the shoot from the plant after rooting has passed.
b) Propagation by cuttings
Cuttings are the most common method of propagation. There should be at least two internodes on the handle, but ideally 3-4. The cutting donor should be last year; that is, it should have an age of 1-1.5 years.
Place the cutting in a water container with the soil having 1 part of perlite and 1 part of fine expanded clay. Also, mix moss, vermiculite, fine expanded clay, or polystyrene, then wait for the roots to appear.
