How many degrees of low temperature can camphor trees withstand?

Cinnamomum camphora is a warm-loving tree species. The most suitable local annual average temperature is 16 ~ 17 degrees, and the lowest temperature is not lower than -7 degrees.

The first water after watering and water spraying in winter should be thoroughly watered, so that the soil and root system can be closely combined, and the gap between the planted soil and the big tree soil ball can be ensured. Usually once or twice.

Cinnamomum camphora needs to be planted to raise seedlings, so talk slowly. This kind of tree can't tolerate low temperature, below MINUS 7 degrees, and it will be frostbitten when cultivated in the open air. When the seedlings overwinter within two years, they should be covered with plastic greenhouses to keep warm.

The greenhouse temperature should not be lower than 0℃ in winter, and the freezing of basin soil will affect the plant roots. Usually in late autumn, after 1 or twice frost drying, move to the sunny window indoors.

Matters needing attention in planting camphor tree

1, ploughing should be done for the first time before freezing in early winter, and ploughing should not be too deep to control the growth of taproot and promote the growth of lateral root. Apply sufficient base fertilizer, usually farmyard manure, before sowing.

2, when there is no rain, should do a good job of watering in the morning and evening. When watering, you should not only thoroughly water the soil, but also wet the trees and bark. However, in the soil with poor drainage, attention should be paid to controlling watering times to avoid root rot caused by excessive soil moisture.

3. Because the roots of trees transplanted in May have not recovered their soil-fixing support ability, they are easily blown down in windy weather (such as typhoon), which affects the recovery of root growth, so it is necessary to support trees in time.
