The ramet propagation can be carried out all year round, and can be carried out in spring in combination with basin change.
Select the plants with more tillers in the base part, remove part of the old basin soil, and use a sharp knife to divide them into several clusters from the junction of the base part. Each clump should not be too small, there must be 2-3 plants, and the root system should be well preserved.
After clumping, apply grass ash or sulfur powder to the wound for disinfection. Then put the plant in the shade and let it dry for a while.
The plants are potted separately, because the root system is not developed, they are placed in a cool place for maintenance, a small amount of water is poured, and water is sprayed daily to the leaf surface to keep it dry. Control the temperature at 20-25 ℃, or the plant will grow slowly.
The growth of sunflower seedlings is slow, it takes 1-2 years to grow into a slightly larger pot. During this period, maintenance should be strengthened.
The seeds of sunflower are not easy to get, if possible, they can be obtained from mature plants.
Wash the flesh of fresh picked sunflower and take out the seeds. The seeds were soaked in 35 ℃ warm water for 2 days. After germination, seedlings can be transplanted into pot.
During the period from germination to leaf growth, water should be replenished in time. Generally, the growth of seedlings is slow, and it needs to be maintained patiently, and it can grow rapidly after it is mature.
