The Latest Cultivation Techniques and Methods Tutorial for Golden Trumpet Tree
Golden trumpet tree, also known as yellow bell tree, Brazilian trumpet tree, Ipe tree, etc., is a deciduous plant of the genus Tabebuia in the family Bignoniaceae. It is often used as an excellent street tree and can also be planted in courtyards, campuses, residential areas, and other places. Its flowers are bright golden yellow, suitable for cultivation and ornamental viewing along roadsides and watersides in parks and green spaces. Now let us take a look at the cultivation techniques for golden trumpet tree!
Growth Habits of Golden Trumpet Tree
Golden trumpet tree is the national flower of Brazil, native to Mexico, Central America, South America, and other places. It prefers high temperatures, with an optimal growth temperature of 20-30°C. In winter, it needs a warm, sheltered location to overwinter. In the northern part of South China, winter temperatures are low and there is abundant rain and humidity, so attention must be paid to cold damage. The best cultivation soil is sandy loam rich in organic matter. Good drainage and sunlight are required.
Propagation Methods of Golden Trumpet Tree
In China, golden trumpet tree is only suitable for cultivation in tropical and subtropical regions. It can be propagated by seeding, cuttings, or air layering, but seeding is the main method, with spring and autumn being the suitable periods. The best cultivation soil is soil rich in organic matter or sandy soil. It prefers high temperatures, with an optimal growth temperature of 23-30°C.
Cultivation Techniques of Golden Trumpet Tree
1. Temperature and Environment: The optimal growth temperature for golden trumpet tree is 23-30°C, and it is not cold-tolerant. During the seedling stage, it also requires relatively strong light. Especially when sowing and raising seedlings in a greenhouse environment, insufficient light and ventilation can easily cause weak seedling growth and damping-off disease. Therefore, after the seeds germinate and the true leaves unfold, ensure that the shading rate of the growing environment does not exceed 50%, while maintaining sufficient ventilation.
2. Soil and Fertilization: For the nursery land used to cultivate large seedlings of golden trumpet tree, choose a place with loose, fertile soil and good irrigation and drainage. Do a good job of planning and arranging drainage and irrigation ditches. Plant about 3000 plants per mu. When planting, apply 250 grams of compound fertilizer or 1 kilogram of organic fertilizer per hole as base fertilizer. The base fertilizer should be thoroughly mixed with the soil before planting the seedlings. When planting seedlings, remove the seedling bag, plant firmly, and compact the soil.
3. Plant Tying: Golden trumpet tree grows quickly during the seedling stage. Its main trunk is soft and prone to lodging and sprouting, and the natural plant shape is often poor. To obtain an upright and straight plant shape, after planting, when the seedling height is 30-50 cm, erect a bamboo support about 2 m tall beside the seedling to guide the plant to grow upright. Tie the plant once every time it grows 50 cm taller.
4. Pruning and Shaping: During the growth period of golden trumpet tree, carry out pruning and shaping regularly, cutting off low-growing lateral branches. After leaf fall in winter, carry out a uniform pruning and shaping, cutting off diseased branches, dead branches, and occasional lateral branches growing from low positions, so as to keep the main trunk growing straight. When the main trunk grows to 1.8-2 m tall, retain the upper branches to form the crown. After 3-4 years of field cultivation, when the plant reaches over 3 m in height and 4-6 cm in diameter, it can be released from the nursery for landscaping.
5. Pest and Disease Control: Golden trumpet tree is often damaged by the coffee wrinkled-chest longhorn beetle. Conduct a general survey of cashew trees 3 times each year. When infested trees are found, immediately use a sharp knife to cut open the bark of the infested tree and remove the longhorn beetle larvae inside. After the wound dries, mound soil to promote the growth of adventitious roots, helping the plant recover its growth vigor. When insect pests are found, use a syringe to inject pesticide into the tunnels to kill the larvae.
