How to propagate Hollyhock flower? Hollyhock can propagate by cutting, sowing and division. The following three propagation methods of Hollyhock and steps of Hollyhocks cutting, sowing and division propagation are arranged.
Hollyhock flower Cutting propagation can be carried out after flowering to winter.
Generally, lateral branches germinating at the base of Hollyhock's old trunk are selected as cuttings, with a length of about 8 cm, and sand soil is generally used as the substrate.
After cutting, cover the seedbed with plastic film, keep certain humidity, and place it in the shade until the roots are born.
Cutting propagation in winter, it is necessary to lay a heating device at the bottom of the seedbed to increase the ground temperature, maintain the temperature of the seedbed, and accelerate the growth of new roots.
The division propagation of Hollyhock is generally carried out in the autumn. Perennial Hollyhock is dug out of the soil and the stem and buds are divided into clusters with a sharp blade, ensuring that each cluster has two or three buds.
They are then planted separately in a substrate, which is usually a fertile, well-drained sandy soil. After planting a flood immediately, the next year it can flower.
In autumn seeds mature and can be applied to sowing propagation, the next year flowering, spring sowing, that year is not easy to flower. In the south, the seeds are often planted in autumn, while in the north, they are mainly planted in spring.
According to the number of seeds, you can choose to sow in the open seedbed, and then transplant, or directly sow in the soil, no longer transplant, soil generally chooses leaf rot soil, field soil. Before sowing propagation, disinfect the soil, prevention and control of diseases and insect pests.
When applying sowing propagation, Hollyhock flower normally germinates in 7 days, and transplant when they have 2-3 leaves. It is best to transplant in overcast and rainy days, and thinning is very beneficial to the growth of the plant.
Hollyhock's seed germinability can be maintained for 4 years, but the growth of the seedlings will decline after two or three years of sowing, and the seedlings are prone to cataplasm. Therefore, the management of the seedbed should be strengthened, and drugs can be properly added to the soil.
