Does hydrangea have seeds?
For most women, do hydrangea flowers have seeds and the topic of flowers and plants about the germination method of hydrangea seeds? Let's follow the editor to see the specific content!
Most of the flowers of hydrangea are sterile flowers and few have mature seeds, so they are usually cultivated by means of asexual reproduction through cuttage and branching.
Cutting, rationing, layering and grafting are commonly used for propagation. Cutting is the main method for propagation. During the plum rain period, you can select strong twigs from young mother trees as cuttings. The base of the cuttings needs to have knots and be dipped in mud. About 20 centimeters long, remove the lower leaves. The suitable temperature for cuttage is 13 - 18℃. Shade is needed after cuttage and is often kept moist. The roots take about 15 days to 1 month. It can be transplanted the second year after survival. Ramet reproduction should be carried out before germination in early spring. Separate the rooted branches from the mother plant, directly potted, not watering too much, maintain them in a semi-shade place, and then switch to normal maintenance after new buds germinate. Layered propagation can be carried out when the buds are germinating and can grow after 30 days. The mother plant is cut off in the spring of the following year and transplanted with soil, so that flowers can be bloomed that year. Generally, high pressure is applied from March to April in spring, and roots can be taken from June to July, and can be cut and planted in that year. Grafting propagation uses Qionghua seedlings as rootstocks, which are cut and grafted in spring, making it easy to survive. Transplanting should be carried out after falling leaves or before germination, and needs to be brought overnight. The main branch is easy to germinate and long branches, and needs to be trimmed properly after flowering to straighten the tree shape.
The suitable growth temperature for cultivating hydrangea is 18~28℃, and the winter temperature is not lower than 5℃. Flower bud differentiation takes 6 to 8 weeks at 5 to 7℃. The temperature of 20℃ can promote flowering, and maintaining 16℃ after flowering can prolong the flowering period. But the high temperature causes the flowers to fade quickly. Hydrangea is a short-day plant that is treated in the dark for more than 10 hours a day and forms flower buds in about 45 to 50 days. Potted hydrangea flowers are commonly used in 15 - 20 cm pots. Potted plants should be fully watered after germination in spring to ensure that the leaves do not wither. During the flowering period from June to July, there should be sufficient fertilizer and water, and fertilizer should be applied once every half month. In ordinary times, we should avoid the scorching sun for cultivation, and 60%~70% shade is the most ideal. Appropriate shade when the light is too strong in midsummer can prolong the flowering period. Remove the flower stems after flowering to promote the production of new branches.
The soil should be loose, fertile and well-drained sandy loam. However, the color is affected by the pH of the soil. The flowers on acidic soil are blue and the flowers on alkaline soil are red. To deepen the blue color, aluminum sulfate can be applied during bud formation. To maintain the pink color, lime can be applied to the soil. The basin soil should be kept moist, but watering should not be too much. Especially in the rainy season, attention should be paid to drainage to prevent waterlogging and causing root rot. In winter, indoor potted plants should be slightly dry. If it is too humid, the leaves will easily rot. The pots are changed every spring.
The above is a comprehensive explanation of whether hydrangea has seeds and the comprehensive knowledge of hydrangea seed germination methods. I hope it can help you.
