1、 Curing method

1. Light: Torreya grandis will grow well in weak sunlight, like cool, and it will thrive in cool places. To avoid direct sunlight, shading is needed. A shading shed can be built. Too strong light is not conducive to its growth

2. Moisture: usually, we must water more to keep the water sufficient. Especially when it is hot in summer, it needs to be watered often. It's better to plant in a place with plenty of rain, and the lack of water will affect its survival rate

3. Soil: Torreya grandis has no excessive requirements for soil, and any kind of soil can be planted. Generally, it needs to grow in fertile and loose land, and can even survive in red soil, sand (stone, gravel), lime soil and rock cracks

4. Temperature: it is very cold resistant. It is afraid of high temperature in summer and frostbite in winter. We must do a good job in antifreeze and thermal insulation. The minimum temperature must not be lower than - 15 ℃

2、 Breeding skills

1. Sowing: seeds can be stored in sand to ensure normal humidity. They cannot be too dry or too wet. Wait until the seed sends out the germ, and then sow it

2. Spend summer: the temperature is relatively high in summer. It needs shading and light transmission. In the plum rain season, it is also easy for the root to decay. At this time, it is necessary to remove the diseased root and prevent the infection from spreading to other good branches and stems

3、 Diagnosis and treatment problems

1. Insect pests: common insect pests include termites, small curly moths, gall mites and rust cochlea. According to the time of invasion, growth and reproduction of these diseases and pests, after adjusting the pesticide concentration, spray according to the time

2. Pruning: if the plant grows too high, it should be pruned from time to time. The height of the tree crown can be controlled at 4-5m, and the crown width should be kept dry and round. After the crown is finalized, it should be regularly trimmed every year. At this time, it is only necessary to cut dense branches and sick and dead branches

4、 Other issues

1. Whether it can be cultured indoors: it belongs to trees and is easy to grow too high, so it is not suitable for indoor maintenance. If the space in the courtyard is large, you can choose to plant in the courtyard

2. Whether it is poisonous: it is not poisonous and can be safely touched. Moreover, the fruit is very beautiful, and it is especially good to plant in the yard
