Why are American teas not good? It's not technical. The weather conditions are too bad. Do you know that?/You know what?

1, poor high temperature resistance, for example, in places like Jiangsu, Zhejiang, Fujian and Hainan, it is undoubtedly not recommended to raise American tea. Such a place is too hot in summer, too wet and cold, and there is no long-term low temperature in winter, which will not help it grow and bloom. If American tea is planted in Jiangsu and Zhejiang, it will basically grow and develop.

2. Low temperature tolerance Generally speaking, the second disadvantage of American tea is that some varieties are not very resistant to low temperature, and some varieties can tolerate ultra-low temperatures of MINUS ten degrees. In a place like the southernmost tip of China, ground planting and maintenance can spend the winter outdoors.

The high temperature resistance of American tea is not very good. If there is too much high temperature in summer, they will be difficult in summer, especially if there are too many wet and cold or rainy days in summer, which is also very unfavorable to their growth and development. Most green plants with good cold tolerance will also have poor high temperature tolerance. What I said is true. Most plants have good low temperature and high temperature resistance except some special varieties cultivated through continuous hybridization, but such plants are rare.

3, sufficient sunshine to maintain American tea also needs a relatively large indoor environment, to be ventilated and bright, and it takes a long period of low-temperature dormancy in winter. You need to give him as much sunshine as possible after spring blossoms. It is not suitable for keeping in a cool place at home. If there is not enough sunshine at home, you can't give him more than 6~8 hours of sunshine every day, which is also very unfavorable for his growth and development. It is not easy to make it blossom in the middle and late stages.

4. Precautions When discussing American tea, many people only see that its color is particularly bright and it can produce blue-purple flowers, so its flowers are clustered into small balls, which looks particularly shocking. But few people will know that the defect is only raised for his flowers, and it is definitely bad not to give it a suitable natural environment.

If the summer is hot and there are many rainy seasons, we must take preventive measures and raise American tea. For example, after the weather gets hot, spray fungicides on time to prevent bacteria from producing, and pay attention to giving him a moderately shaded living environment in summer. Also, pay attention to provide him with more breathable loose soil to prevent the soil layer from being actually wet and cold, especially on rainy days. If the soil layer is always wet and cold, causing root rot, it will be difficult to save.

5, bonsai soil and inverted pots, such as potted American tea seedlings, are purchased at first, so after buying back, you can add more granular soil to the soil to improve the permeability of the soil, and you can use common granular soil such as slag and volcanic rocks. This granular soil can account for about 30% of bonsai soil. The growth requirements of American tea can basically be met by mixing some peat soil, coarse coconut bricks, vitrified beads and adding some compound fertilizer. If you just bought potted seedlings of American tea, if you have potted plants with bonsai soil and the plants are in good condition, you can pour them directly after you buy them. Of course, you can also pour the pot after 3~4 days. If the plant is in good condition, you can gradually increase the sunshine the next day and slowly turn to the part with sufficient light to restore its growth and development as soon as possible.
