Originated in Lan Yu Island, it is a bright green and auspicious Lan Yu cinnamon (Cinnamomum cassia, safety tree, safety tree). Entering the family in recent years will be loved by flower lovers. Produced in southern Taiwan Province Province (Lan Yu).

The origin of the name "Peace Tree": "Peace Tree" is the nickname of Lan Yu cinnamon. Because its bark can be used as medicine, it has the effects of expelling wind, dispelling cold, relieving pain, removing blood stasis, promoting blood circulation and invigorating stomach, and because its plants are rich in cinnamon oil (mainly cinnamaldehyde), it can also emit the fragrance of correcting odor and purifying air. People in the flower planting and management industry have given it an auspicious name "Peace Tree" to cater to the urban people's consumption psychology of loving green and beauty and hoping for safety, and also to let people relax in the intense work.

Key points of management

Temperature: Its growth temperature is 20℃ to 30℃. Small trees are intolerant of low temperature. If exposed to frost for more than 5 days, plants maintained or cultivated in the wild can easily lead to bark cracking, branches and leaves withering, and even the whole plant freezing. Whether a small number of plants are potted at home or cultivated in a large area, the greenhouse temperature should be kept not lower than 5℃ in winter to keep their leaves green all the time. Larger plants can endure the low temperature of about 0℃ for a short time, and there is no cold wind blowing in the shed. Potted plants in the Yangtze River basin should be moved into the shed before the first frost comes, and then go out after Qingming the next year. Attention should be paid to the possible cold damage caused by late frost or late spring cold. In midsummer, when the temperature exceeds 32℃, it is necessary to build a shed for shade and spray water on the leaves to humidify and cool them and maintain their vigorous growth potential.

Lighting: Cinnamon in Lan Yu needs better lighting, but it is more shade-tolerant. Its demand for light changes with age. Young trees are shade-tolerant, 3-5-year-old plants grow fast under shade conditions, and 6- 10-year-old plants need sufficient light. Potted plants can be placed in the shade or under the awning with 40% to 50% shade in summer, and their growth is ideal. If the light is too strong, it is easy to cause the leaves to turn yellow and lose their ornamental value, especially for potted plants that have been placed indoors for a long time. They must be careful when they are moved outdoors for restorative maintenance in summer. They should be kept in 40% to 50% shading environment first, and they should not be rushed, otherwise it will easily cause blade burns. In addition, in the late spring and early summer, in case of sunny weather after a long rain in Chu Qing, we should also do a good job of shading in time, otherwise it will also cause burns to the leaves, and it will be difficult to restore their green and lush spirit in a short time.

Moisture: Cinnamon in Lan Yu needs a humid environment. Therefore, potted plants should always keep the soil moist, but there should be no water, and the relative humidity of the environment should be kept above 80%. In hot summer or dry autumn air period, including indoor period in winter, we should often spray water on leaves and surrounding environment to create a relatively humid local space and small environment for them and promote their vigorous growth. Water should be controlled after autumn, and more water should be sprayed and less water should be watered in winter. If there is water in the basin soil, it will easily lead to yellowing of plants, and the lower leaves will fall off after yellowing. In severe cases, it will lead to the root rot and death of plants, and special attention should be paid in rainy season.

Soil: Potted or bagged Cinnamon In Lan Yu, fertile acidic culture soil or humus soil with loose air permeability, smooth drainage and rich organic matter should be used. Potted soil hardening or pH value higher than 7.5 will also cause yellowing of plant leaves, serious poor growth, decreased germination ability, affecting bud regeneration and even shortening its cultivation life. Therefore, small plants should change pots once a year, big plants can change soil once every two years, and loosen soil once a month during the growing season. Especially after the heavy rain, it is necessary to check the flowerpots in time. When water is found in the pots, it should be dumped as soon as possible and the loose soil should be replaced. For potted plants, it is best to arrange the time to turn over the pots and change the soil every year after leaving the house in spring to before germination.

Fertilizer: Cinnamomum cassia plants in Lan Yu are plump, with huge leaves and vigorous growth, which requires a lot of fertilizer. Potted cinnamon in Lan Yu requires fertile soil, and pancake fat water or fat alum water can be applied once a month from mid-spring to early autumn. After autumn, phosphorus and potassium fertilizer should be applied twice continuously, such as 0.3% potassium dihydrogen phosphate solution, to increase the cold resistance of plants, promote the early lignification of shoots and overwinter safely. In winter, all forms of topdressing should be stopped, so as not to damage the roots and cause the leaves to yellow or wither, otherwise it is difficult to restore the original appearance of plants. [
