Night-blooming jasmine propagation methods
Let's talk about the topic of night-blooming jasmine propagation in flower breeding. Here are the methods for propagating night-blooming jasmine, let's learn about them together.
Night-blooming jasmine is commonly propagated by cuttage. Let's take a look at how to propagate night-blooming jasmine through cuttage:
1. Select cuttings: Choose branches that are healthy or free from diseases and pests, preferably the sun-exposed branches from the upper part of the plant of the current year. The branches should have short internodes, robust leaves, and plump buds. Avoid using branches that are about to bloom or overgrown ones.
2. Select substrate: Use peat soil, decomposed leaf soil, and sand mixed in a ratio of 3:3:4. This mixture of potting soil has the characteristics of raising bed temperature, water retention, aeration, fertility, and slight acidity, which is suitable for the roots and sprouts of the branches.
3. Treat cuttings: Before cuttage, treat the cuttings with agents such as ABT rooting powder to promote root growth. Cut the cutting into a section of 8 to 12 centimeters, with 2 to 3 buds at the top. The lower cut should be 0.5 centimeters below the node, and the cut should be smooth. Remove the lower leaves, leaving only 2 to 3 leaves at the top, and plant the cutting about 3 centimeters deep.
4. Create conditions for root growth: The suitable temperature for root growth is between 20°C and 24°C. Generally, a soil temperature 3°C to 5°C higher than the air temperature is beneficial for root growth. The relative humidity of the cutting bed should be between 80% and 90%, which is conducive to root growth, and requires about 30% light. The moisture should be appropriate, with more water in the early stage of cuttage and slightly less in the later stage. The suitable period for outdoor cuttage in this area is from early May to mid-June, when the weather is good and can better meet the temperature and humidity conditions required for root growth of the cuttings.
5. Strengthen post-cutting management: After cutting, water thoroughly, cover with plastic film, place in a shaded area, or sprinkle the film with hay to prevent direct sunlight, and increase lighting at night to help the cuttings survive. Ventilate once or twice a day to supplement the required oxygen and prevent diseases. Frequently spray water to keep the cutting bed moderately moist, but do not overwater, as excessive moisture can affect the healing and rooting of the cuttings. When the new roots of the cuttings grow to 2 to 3 centimeters, they can be transplanted to pots at the right time. In winter, after flowering, the plants should be moved indoors for care in the Nanjing area.
