The sowing and propagation of six flowers usually take place in winter. The sand and peat soil were sterilized in a ratio of 1:1 at high temperature and then put into a basin as the seeding substrate. Seed from mid October to late November. In the winter 0 ℃ to 5 ℃ natural low temperature, the seeds gradually wake up.
Move it to 15 ℃ to 20 ℃, and the seeds can germinate for about two weeks. The germination rate is over 80%. After germination, keep the temperature between 10 ℃ and 20 ℃. Six flowers grow fast. When the seedlings grow to 4cm to 5cm, they should be planted separately. The time of separate planting should be from February to march in early spring. It should be noted that the root system should not be damaged during separate planting.
In addition to sowing and propagation, six flowers can also be propagated in separate plants. The ramet propagation time of six flowers is in October. The branch propagation of hexaploid flower is to utilize the non germinated dormant buds on the rhizome of hexaploid flower. When the rhizome of six flowers is cut into sections, the dormant buds can be stimulated to germinate into new plants.
The rhizome of Liuchu flower lies in the ground, and there are raw fleshy roots on the rhizome, which can help Liuchu flower to store water and nutrients. When the condition is suitable, the horizontal rhizome will stretch in the soil, at the same time, some of the dormant buds will gradually germinate until they grow into flower branches.
Before planting, the soil should be loose, dry and wet. When dividing plants, the upper part of the plants 30 cm above the ground should be cut off. When digging up the plant, it is necessary to avoid damaging the root system as much as possible. Gently shake the soil around the plant and plant the roots on the prepared seedbed. If it is a plant for cut flower cultivation, the row spacing is generally 40cm × 50cm.
