Parthenocissus tricuspidata is a perennial large deciduous woody vine of the grape family, similar in appearance to wild grape vines. Also known as climbing ivy, ground cover, flying centipede, false grapevine, red silk grass, and stone blood. The epidermis of Parthenocissus tricuspidata has lenticels, with dense leaves in summer, often climbing on walls or rocks, suitable for planting near house walls, fences, garden entrances, bridgehead stones, etc. It can be used to green house walls and park rocks, beautifying the environment and cooling the air, regulating humidity, and reducing noise.
Parthenocissus tricuspidata is native to China, with strong adaptability, prefers shady and humid environments but is not afraid of strong sunlight, cold-resistant, drought-resistant, and poverty-resistant. It has a wide climate adaptability and can maintain semi-evergreen or evergreen states in warm temperate regions and southward in winter. It is tolerant to pruning, dislikes waterlogging, and is not strict about soil requirements. It can grow robustly in shady or sunny environments, but grows best in shady, fertile soil. It has strong resistance to harmful gases like sulfur dioxide and hydrogen chloride and has the ability to absorb dust in the air.
Parthenocissus tricuspidata is easygoing, occupies little space, grows fast, and covers a large area of greenery. A vine with a stem diameter of 2 centimeters, planted for two years, can cover an area of 30-50 square meters on walls.
The morphology of Parthenocissus tricuspidata is similar to that of wild grape vines, with tendrils that develop into small suction cups at the tips. When they encounter objects, they secrete adhesive fluid to adhere to other objects, allowing the plant to grow forward. Both exposed walls and trees can serve as supports for it, which is how the name "climbing ivy" came about. Its leaves turn red after frost, making it very beautiful and a good material for vertical greening.
I. Propagation methods of Parthenocissus tricuspidata: There are seed propagation, cutting propagation, and layering propagation.
1. Cutting propagation: Parthenocissus tricuspidata cuttings root easily and can grow over 1 meter long in the first year. Both hard branches in early spring or tender branches in summer can root easily. Cut branches 10-15 centimeters long, insert them into open ground seedbeds, water them, and keep the seedbeds moist to root quickly. The survival rate of cuttings is high and widely used. Hardwood cutting is done from March to April, cutting the branches into 10-15 centimeters long and inserting them into the soil, watering thoroughly and keeping them moist. Tender branch cutting takes place with new branches in the summer.
2. Layering propagation: Low layering and high layering are commonly used.
Layering propagation: Low layering is done in early spring by selecting branches close to the ground, making a 1-centimeter cut with a knife (the position of the cut should be buried in the soil when the branch is pressed into the ground), and covering the cut part with soil. Press it down with a stone, keep the top of the branch facing up, and prevent it from swaying. When it's time to plant, dig the soil and observe. Cut the rooted layered branches from the end close to the mother plant to become planting seedlings.
High layering method: High layering, also known as aerial layering, is done on 2-4-year-old vines that are growing vigorously, 20-30 centimeters away from the base branch. First, strip half to two-thirds of the bark with a ring-shaped stripping method, then wrap the wound with a mixture of fertilizer and high-quality soil into a ball shape, and cover it with plastic film to keep it moist. The high layering time is generally in early spring, from February to March. By August to September, white roots can be seen through the plastic film, and the layered branches are cut off 3-5 centimeters below the ball, which must be immediately planted. Milan usually roots in about 3 months after high layering.
3. Seed propagation: After harvesting, the seeds are rubbed to remove the fruit skin and flesh, washed and dried, and can be stored in wet sand at low temperatures for the winter. Keeping warm and moist is conducive to germination. In early to mid-March of the following year, you can broadcast the seeds in the open ground, cover them with plastic film, and seedlings can emerge by early May. It takes 1-2 years to grow before they can be transplanted.
II. Cultivation and Management
Planting can use 1-2-year-old seedlings. When planting, keep a distance of more than 50 centimeters from the wall to increase the root nutrient area and protect the foundation. When digging the planting pit, be aware that there are often bricks, stones, and other construction waste in the backfill soil of buildings. Good soil must be used to replace it, and some fertilizer soil should be added to supplement fertilizer. After planting, pay attention to guide the branches towards walls, rockeries, or old trees as much as possible. Planting it near house walls or garden walls can be spaced 2 meters apart. If too sparse, the effect is slow, and if too dense, it is too crowded. Parthenocissus tricuspidata can be planted on both shady and sunny sides, and it is better to plant in sunny areas in cold regions. It has strong resistance to chlorides and is suitable for cultivation in industrial and mining areas with serious air pollution. Seedlings can be managed loosely after one year of growth and can endure -20℃ in winter without cold protection. Transplanting or planting is done during the defoliation period. Before planting, apply organic fertilizer as a base fertilizer, cut off the long stems, and water thoroughly to ensure easy survival.
