What are the key points to note when growing the golden trumpet tree (Handroanthus chrysotrichus)?

The golden trumpet tree shows obvious changes through the four seasons. Spring flowers, summer foliage, autumn dew and winter dryness add color to this season. The tree has a beautiful shape, vivid color, fast growth and strong adaptability. It is an excellent landscaping tree species, but what points need attention when propagating it? Let us look at the key points to note when planting the golden trumpet tree.

Key points to note when cultivating the golden trumpet tree

1, Temperature

Generally speaking, this plant grows best under conditions of 23 to 30 degrees, and cannot adapt well to the cold season, so in China, many people in the south grow it.

2, Lighting

This plant needs a large amount of light during the sprouting period, but if the plant is grown in a greenhouse, due to insufficient ventilation and air movement, the growth of the seedlings may weaken, and they may then be taken over by disease. Therefore, after the seeds sprout and the leaves grow, it must be ensured that the shading degree of the cultivation environment does not exceed 50%, and the ventilation conditions of the environment must be ensured.

3. Soil

To plant large seedlings, some loose and fertile soil should be chosen, and the soil should have good filling or drainage capacity. These cultivated soils should be divided into good ditches for drainage and irrigation, with about 3000 plants per mu.

4. Flower fertilizer

Before planting, some flower fertilizer should be buried in the soil as base fertilizer, and these base fertilizers should be fully mixed with the soil, then planting can be done.

5. Tying

Because this plant grows very fast during the sprouting period, its main branches are very soft and easily fall down due to wind, so the shape of naturally growing plants is often less attractive. If you want a taller plant, you should insert a 2-meter-high bamboo behind the seed to support the plant, when the seedling grows to 30 to 50 cm high. It can be kept upright. The seedling should be tied once every 50 cm of growth.

6, Pruning

Prune the plant regularly during the growth period, cut off the relatively short branches growing from the sides, and cut them once after the leaves fall in winter.

Pest and disease control measures for the golden trumpet tree

1. Coffee wrinkled bark borer pest

The coffee wrinkled bark borer is a beetle and is one of the most common pests of the golden trumpet tree. Generally, it is necessary to inspect the golden trumpet tree three times a year in order to discover the damage of the beetle in time.

If inspection shows that the golden trumpet tree has been infested by the beetle, the affected part must be cut off with a sharp tool, and then you can find young eggs or insects inside. At this time, the pests need to be removed, and then the cut bark should be dried and then filled, so that the plant can recover.

Another simple method is to inject insecticide into the insect's bark when the beetle infestation is found, and this can kill the beetle larvae.

2. Leaf spot disease

Whenever spring warms up, everything begins to sprout, but at this time the golden trumpet tree will be troubled by leaf spot. Leaf spot is a disease that most plants will suffer from. When you encounter this disease, do not worry, there are some ways to treat it.

Generally, the method for treating leaf spot is used, and then spraying the flowers so that they are treated and controlled, or a relatively strong pesticide can be used, which has a great effect on the disease and can be applied by continuous spraying several times.

Daily maintenance

It grows fastest in a climate of 25 to 30 degrees and is not suitable for growing at cold temperatures, so be sure to maintain a suitable climate, otherwise it can easily lead to slow development. Second, the planting soil needs to be chosen as loose and relatively strong soil, and then some fertilizer can be added as base fertilizer to promote its rapid development. It can be pruned appropriately during the growing season, which helps produce other branches and helps its landscaping.
