The signature tree is an evergreen tree. Because the characters carved on its leaves can last for a long time, it is called the signature tree. Below is the relevant content I have compiled for you about the methods and precautions for growing signature trees. I hope it can help you. How to cultivate signature trees

Soil

Signature trees are not very strict about soil requirements, but they must ensure that the soil has the characteristics of loose drainage and good air permeability. It is better to be dry than wet. a little.

Temperature

The signature tree has a warm and humid environment. It is best not to have too low a temperature during the winter, otherwise it is likely to freeze to death.

Lighting

Signature trees are suitable for cultivation in an environment with sufficient light. However, in the summer when the sun is more toxic, proper shade is needed, otherwise sunburn and spots on the leaves may occur. If maintained in a place with insufficient light, it will lead to leggy growth, the leaves may turn yellow, and the distance between the leaves will change. long.

Fertilization

For fertilization, it is the same as for other flowers and trees, mainly nitrogen fertilizer.

Pruning

For potted signature trees, reasonable pruning is required to control the plant shape. In addition, cuttings and sowing methods can be used to propagate signature trees. Cultivation method of signature tree

Potting

Use imported peat of 5-40mm size with loose, good drainage and ventilation, crush the peat with a machine, add water and mix well (add water Standard: add water and mix well, hold a handful of peat in your hand, water seeps out from between your fingers) and wait for planting in the cup. The amount of peat in each 7.5cm pot is about 200 ml. A pack of 300 liters of imported peat can hold about 1,500 cups.

Requirements for screening seedlings

Choose professionally produced high-quality seedlings. 4-5cm high, 10-12 leaves, no pests and diseases, no dead leaves or yellow leaves

Upper pot

For reused old pots, potassium permanganate must be used Soak in 1000 times liquid for more than half an hour, then rinse with clean water and dry for later use. The new pot can be used directly. Generally, a smaller flowerpot (7.5cm plastic cup) is used for planting first. When planting, first place about 2cm of substrate at the bottom of the cup, and then move the screened seedlings into the cup. The seedlings should not be planted too deep, and it is appropriate to level the base of the plant, 1- 2 plants/pot; the substrate should be moderately tight, fill the cup until it is 90% full, and shake the pot soil gently.

Effects of light

(1) If planted under full sunlight in summer, new leaves are prone to sunburn.

(2) Planted outdoors under semi-shade conditions, the average height of the first planted seedlings is 5.0cm, and the average plant height is 5.2cm one month after planting.

(3) For planting in greenhouses, the maximum light intensity is controlled at around 15,000 Lux. The average plant height is 4.7cm when first planted, and the average plant height is 7.1cm one month after planting.

Moisture: In the seedling stage, the stems are slightly fleshy. Just keep the substrate moist. Don't make it too dry or too wet, otherwise stem rot and root rot will easily occur. If the seedlings are planted outdoors during the seedling stage, the substrate will be too wet during continuous rainy days, and stem rot and root rot will also occur. Therefore, they are generally planted in a shed.

Humidity: Because the leaves are leathery, the signature tree does not have strict requirements for humidity. Generally, the humidity can be kept at 65 or lower.

Fertilizer and water management: During the seedling stage, Luyuan Fertilizer 10-30-20 and Merilai 14-0-14 are diluted 1500-2000 times for rotation. The interval between water and fertilizer is about once a week. Or put some Meililai controlled-release granular fertilizer (15-15-15) on the surface of the substrate, 5g per pot. Precautions for breeding signature trees

During the breeding process, signature trees are susceptible to infestation by some pests and diseases.

In terms of insect pests, the main damage is caused by thrips. The new leaves of the signature tree will be eaten by thrips. In the early stage of the disease, 1500 acetamiprid can be used to control it. In terms of diseases, the main one is anthrax. Once the disease occurs, the diseased leaves of the signature tree can be removed, and then sprayed with 800 times of chlorothalonil for control, 3 to 4 times continuously, and once every 4 to 5 days.
