Cannon Flower (Pyrostegia venusta) Cutting Propagation Methods and Post-Planting Management Tips
Although there is more than one breeding method for the cannon flower, the commonly used method is cutting propagation. This method is very convenient to carry out and easy for the plant to survive. After cutting, the most important thing is post-planting management. Below, the editor introduces the cutting method and post-planting management of the cannon flower. I hope everyone enjoys it.
Preparation Before Planting Cannon Flower Cuttings
Cutting Selection
It is usually suitable to take cuttings from 2-year-old vines from May to June, or from September to October. At this time, semi-lignified vines are selected and cut during the period before they stop growing, up to flower bud differentiation. These cuttings are suitable when taken from middle vines, short vines with complete buds and vigorous growth.
Cutting Treatment
Cut the cuttings into 2-3 sections, with the cuts made diagonally and smooth. The upper part of the cutting should retain 2-3 small leaves, which is beneficial for root promotion. Treat with potassium permanganate solution before using ABT rooting powder.
Cannon Flower Cutting Method
Use the trenching method, insert diagonally, go halfway into the substrate, leave a section above ground, and insert into water.
Post-Planting Management of Cannon Flower
Light and Temperature
For cutting propagation, the temperature in May is usually stable at 20-25°C. When the soil temperature in the seedbed is 3-5°C higher than the air temperature, it is more favorable for rooting. A double-layer shade net should be used for shading, and one layer of net should be removed about 2 weeks after insertion. About one month after insertion, most cuttings have formed callus tissue. The shade net should be opened in the morning or evening, and the cuttings should be properly exposed to the sun to promote rooting.
Moisture
Usually, the cutting bed is kept moist while maintaining 80%-90% air humidity, which is favorable for rooting, and water can be sprayed 1-2 times a day to increase air humidity. When the sprouted roots grow to about 2 cm, the amount of water can be increased. At the same time, it is better to let the bed soil dry out for a period and then water it.
Fertilization
When the roots of the cuttings are about 1 cm long, a potassium-containing liquid fertilizer can be sprayed. When the roots of most cuttings reach 3 cm in length, a ternary liquid fertilizer can be applied once every half month to promote the growth of leaf buds.
