How to Propagate Common Hollyhock Flower
Common hollyhock is widely distributed in China. It is grown in many areas. When the flowers are in full bloom, they cluster together. Let's have a look at the propagation methods of Common hollyhock.
Common Hollyhock Propagation from Seed
You can propagate hollyhock in August or September when the seeds are ripe, and it blooms flowers in the next spring. If you sow in the spring, it will not flower that year. 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, disinfect the soil, to prevent and control of diseases and insect pests.
They normally germinate 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.
Common Hollyhock's seed germinability can be maintained for 4 years, but the growth of seedlings will decline after two or three years of sowing. Seedlings are prone to cataplasm. Therefore, the management of the seedbed should be strengthened, and drugs can be properly added to the soil.
Common Hollyhock Propagation from Division
Common Hollyhock's division propagation is usually done in the fall. The perennial common hollyhock is dug out of the soil, and the stem 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 bloom.
Common Hollyhock Propagation from Cutting
Cutting propagation of Common Hollyhock can be carried out after flowering to winter.
The lateral branches germinating at the base of Common Hollyhock's old stem are generally selected as cuttings, with a length of about 8cm, 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 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.
