What are the planting methods for the golden trumpet tree?

I. Temperature control

The golden trumpet tree prefers a sunny environment, with an optimal temperature of 23-30°C. It is not tolerant of severe cold, and also needs strong light during the seedling stage, avoiding excessive shading, while also requiring good ventilation.

II. Soil and fertilizer

For planting the golden trumpet tree, it is best to choose loose, fertile, and well-drained soil. When planting, about 250 grams of compound fertilizer should be sprinkled into the tree hole as base fertilizer. The base fertilizer needs to be mixed and stirred evenly with the soil before planting the sapling.

III. Shaping and pruning

During the growth period, the golden trumpet tree needs regular pruning and shaping, cutting off low-growing lateral branches. After the leaves fall in winter, a pruning and shaping should also be carried out, cutting off diseased branches, dead branches, and low-growing lateral branches, so as to preserve the nutrients of the main trunk and make it grow straight.

IV. Pest and disease control

The golden trumpet tree is susceptible to damage from the coffee borer beetle (Xylotrechus quadripes). The trees need to be inspected every year, and when pests or diseases are found, the affected bark should be immediately cut open or the affected branches should be pruned off, and the beetle larvae removed.

The golden trumpet tree takes on varied forms and appearances as the seasons change, so which season and which time does the golden trumpet tree grow best and have the most ornamental value? Let's take a look together at the best viewing period for the golden trumpet tree!

The golden trumpet tree, also known as yellow bell tree, Brazilian trumpet tree, ipê tree, etc., is a deciduous plant of the genus Handroanthus 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 golden yellow and bright, suitable for cultivation and viewing along roadsides and watersides in parks, green spaces, and other areas. Let's take a look together at the cultivation techniques of the golden trumpet tree!

Growth habits of the golden trumpet tree

The golden trumpet tree is the national flower of Brazil, native to Mexico, Central America, South America, and other places. It likes high temperatures, with an optimal growth temperature of 20-30°C. In winter, it needs a warm, wind-sheltered place to overwinter. In the northern part of South China, winters are low in temperature and also rainy and humid, so attention must be paid to cold damage. The best cultivation soil is sandy loam rich in organic matter. Drainage and sunlight must be good.

Propagation methods of the golden trumpet tree

In China, the golden trumpet tree is only suitable for cultivation in tropical and subtropical regions. It can be propagated by sowing, cuttings, or air layering, but sowing 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 likes high temperatures, with an optimal growth temperature of 23-30°C.

Cultivation techniques of the golden trumpet tree

1. Temperature environment: The optimal growth temperature for the golden trumpet tree is 23-30°C, and it is not cold-tolerant. During the seedling stage, it also requires strong light, especially when sowing and raising seedlings in a greenhouse environment, where insufficient light and ventilation can easily cause weak seedling growth and damping-off disease. Therefore, after the seeds germinate and the true leaves unfold, it is necessary to 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 the golden trumpet tree, a place with loose, fertile soil and good irrigation and drainage should be chosen. Planning should be done well and drainage and irrigation ditches should be prepared. 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 fully mixed with the soil before planting the seedlings. When planting seedlings, remove the seedling bag and plant firmly, pressing down the soil.

3. Plant tying: The golden trumpet tree grows quickly during the seedling stage, and its main trunk is soft, making it prone to lodging and easy to produce sprouts. 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, a bamboo support about 2 m tall should be erected beside the seedling to guide the plant to grow upright. Tie the seedling once every time it grows 50 cm taller.

4. Pruning and shaping: During the growth period, the golden trumpet tree should be regularly pruned and shaped, cutting off low-growing lateral branches. After the leaves fall in winter, a unified pruning and shaping should be carried out, cutting off diseased branches, dead branches, and low-growing lateral branches, 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 a 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: The golden trumpet tree is often harmed by the coffee borer beetle (Xylotrechus quadripes). Conduct a general survey of the cashew trees 3 times a year. When damaged trees are found, immediately use a sharp knife to cut open the bark of the affected tree and remove the beetle larvae inside. After the wound dries, mound soil to promote the growth of adventitious roots, so as to help the plant recover its growth vigor. When insect damage is found, pesticide can be injected into the tunnel with a syringe to kill the larvae.

Key cultivation points of the golden trumpet tree

The golden trumpet tree is a tree that changes its appearance with the four seasons. It is very special and displays a unique appearance throughout the year. The cultivation difficulty of the golden trumpet tree is not high, and its adaptability is also relatively strong. When the environment is suitable for growth, the golden trumpet tree can grow relatively well.

III. Cultivation

A suitable plant spacing is 2.5 m * 2.5 m. Dig holes at least 50 cm * 50 cm * 40 cm. Apply about 10 jin of fertilizer, mixing 75% livestock and poultry manure, 18% phosphate fertilizer, 7% potassium fertilizer, and a trace amount of zinc sulfate (to promote tillering and branching and make the crown full) as base fertilizer. Topdressing should be applied frequently and lightly, once every two months. Apply urea the first time, and compound fertilizer thereafter. The branches of the golden trumpet tree are soft, so be sure to set up stakes to keep it upright.
