The Ping'an Tree is an elegant name for Cinnamomum kotoense (Lanyu cinnamon). It can emit a fragrance that corrects odors and purifies the air. Flower cultivation and business professionals gave it an auspicious name, "Ping'an Tree." The Ping'an Tree symbolizes good fortune, peace and prosperity, and a happy life. Below, the editor will give you a detailed introduction to the cultivation methods and precautions for the Ping'an Tree.

Cultivation Methods for the Ping'an Tree

1. Temperature. The suitable growth temperature for the Ping'an Tree is 20°C to 30°C. Young trees are not tolerant of low temperatures. If frost lasts more than 5 days, plants maintained or cultivated in the open field are prone to bark frost cracking, withered branches and leaves, and even the entire plant freezing to death. Whether it is a small number of plants potted at home or large-scale commercial cultivation, the greenhouse temperature in winter should be maintained at no less than 5°C so that the leaves can always maintain their beautiful green appearance. Larger plants can endure short periods of low temperatures around 0°C in a greenhouse without cold wind blowing. For potted plants in the Yangtze River Basin, they should be moved into the greenhouse before the arrival of Frost's Descent, and moved out after Qingming the following year. Attention should be paid to preventing cold damage that may be caused by late frost or a late spring cold snap. In midsummer, after the temperature exceeds 32°C, shade nets should be set up and water should be sprayed on the leaves to increase humidity and lower temperature, so that the plants can maintain vigorous growth.

2. Light. The Ping'an Tree needs relatively good light, but it is also fairly shade-tolerant. Its light requirements vary with age. Young trees are shade-tolerant. For 3- to 5-year-old plants, under shaded conditions, plant height grows quickly. For 6- to 10-year-old plants, relatively sufficient light is required. After potted plants enter summer, they can be moved under tree shade or under a shade shed with 40% to 50% shading, where growth is relatively ideal. If the light is too strong, it easily causes the leaves to turn yellow and lose their vitality, reducing their ornamental value. Especially for potted plants that have been displayed indoors for a relatively long time, when they are moved outdoors in summer for restorative care, one must be very careful. It is best to first place them in a 40% to 50% shaded environment for care, and one must not be too hasty, otherwise it is very easy to cause leaf scorch. In addition, in late spring and early summer, when encountering weather with strong sun after a long period of rain, shading work should also be done in a timely manner, otherwise it will likewise cause leaf scorch, and it will be difficult to restore the fresh green and lush spirit of the leaves in a short time.

3. Water. The Ping'an Tree requires an environment with moist potting soil. For this reason, potted plants should always keep the potting soil moist, but there must be no standing water. The relative humidity of the environment is best maintained above 80%. In the high-temperature summer season or in autumn when the air is relatively dry, including during the period when placed indoors in winter, water should be sprayed frequently on the leaves and the surrounding environment to create a relatively humid local microenvironment for it and promote robust growth. After autumn begins, watering should be controlled. In winter, more spraying and less watering should be done. If there is standing water in the potting soil, it easily causes the plant to turn yellow, and the lower leaves will turn yellow and fall off. In severe cases, it will cause root rot and death of the plant. Special attention should be paid during the plum rain season.

4. Soil. For potted or bag-cultivated Ping'an Trees, it is best to use loose, breathable, well-drained, organic-rich, fertile acidic culture soil or leaf mold. If the potting soil is compacted or the pH value is above 7.5, it will also cause the leaves to turn yellow, seriously poor growth, and reduced sprouting ability, and will affect sprout renewal, and even shorten its cultivation life. For this reason, small plants should be repotted once a year, and large plants can have their soil changed once every 2 years. During the growing season, loosen the soil once a month. Especially after heavy rain, check the flowerpot promptly. If standing water is found in the pot, pour it out as soon as possible and replace it with loose potting soil. For potted plants, the annual time for repotting and changing soil is best arranged after they are moved out in spring and before sprouting.

5. Fertilizer. Ping'an Tree plants are full in form, have large leaves, and grow vigorously, so they also have a relatively large fertilizer requirement. In addition to requiring fertile culture soil, potted Ping'an Trees can be topdressed once a month from mid-spring to early autumn with diluted cake fertilizer water or alum fertilizer water, etc. After autumn begins, phosphorus and potassium fertilizers should be applied continuously 2 times, such as a 0.3% potassium dihydrogen phosphate solution, in order to increase the plant's cold resistance, promote early lignification of tender shoots, and help it pass winter safely. In winter, all forms of topdressing should be stopped to prevent fertilizer damage to the roots, which can cause leaves to turn yellow or become scorched and fall off, otherwise it will be very difficult to restore the plant's original appearance.

6. Disease Control

① Anthracnose: It mainly harms leaves at the seedling stage and adult plants. When leaves are infected, it mostly occurs on the leaf surface, leaf tip, and leaf margin, appearing brown and irregular in shape. Later, it often expands or merges into large gray-brown spots with brown wavy edges. Many small black dots grow on the lesions, which are its acervuli. Conidia spread through wind and rain. When humidity is high, the spores germinate and invade leaves or seedlings to cause damage. The disease is likely to occur during continuous cloudy and rainy weather, insufficient sunlight, heavy clay soil, or stagnant moisture in the greenhouse, and it is most prevalent from February to April. Control methods: If a small number of diseased leaves are found, remove and destroy them promptly; during the growing season, apply more phosphorus and potassium fertilizers to improve plant resistance; in the early stage of the disease, alternately spray with 25% carbendazim wettable powder at 500 times dilution, or 60% carbendazim wettable powder at 700 times dilution, or 75% thiophanate-methyl wettable powder at 600 times dilution, once every 10 to 15 days, for 3 to 4 consecutive times.

② Brown spot disease: It occurs on new leaves of plants from April to May. At first, oval yellow-brown lesions appear on the leaf surface, then continuously expand, and more small black spots appear inside the lesions on the front of the leaf. The back of the lesion is purple, causing the entire leaf to turn yellow and wilt, making the plant shed a large number of leaves. Control methods: 1% Bordeaux mixture can be used for prevention; if a small number of diseased leaves appear, remove and burn them promptly; in the early stage of the disease, alternately spray with 50% carbendazim wettable powder at 500 times dilution, or 50% benomyl wettable powder at 1000 times dilution, or 50% shajunwang aqueous solution at 1000 times dilution, once every 10 days, for 3 to 4 consecutive times.

③ Brown root rot: The leaves of diseased trees gradually turn yellow and droop. In severe cases, they turn brown and dry up, the stems lose water and shrink, the root system turns brown and rots, and the diseased plants die within a short period. Diseased roots, diseased soil, and remaining diseased debris are the primary infection sources of this disease. It is transmitted by wind and rain or contact, and generally occurs in individual plants. Control methods: For severely diseased plants and plants that died from the disease, pull them out by the roots and burn them, and disinfect with 50% carbendazim wettable powder at 600 times dilution; in the early stage of the disease, spray with 50% thiophanate-methyl? sulfur suspension at 800 times dilution, or 50% genfuling wettable powder at 800 times dilution for control.

7. Pest Control

① Leaf roller: It mostly occurs in summer and autumn. It rolls several new leaves into a nest, and the larvae hide inside and feed on the leaves. It can be sprayed and killed with 90% trichlorfon crystal at 800 times dilution, or 40% dimethoate emulsifiable concentrate at 1000 times dilution.

② Aphids: Aphids are prone to sucking and damaging the tender leaves and new buds of the Ping'an Tree, causing the leaves to become covered with grease, and then inducing sooty mold, affecting plant growth and display ornamental value. Control methods: After spreading plant ash on the plant, rinse it clean with clear water; spraying chinaberry leaf juice can effectively kill insects; spray and kill with 10% imidacloprid wettable powder at 2000 times dilution.

Precautions for Cultivating the Ping'an Tree

1. If a small number of diseased leaves appear, remove and burn them promptly; avoid the entire leaf turning yellow and wilting, which causes the plant to shed a large number of leaves.

2. During plum rain weather, prevent standing water in the pot. If there is standing water in the potting soil, it easily causes the plant to turn yellow, and the lower leaves will turn yellow and fall off. In severe cases, it will damage the roots and stems, and even cause root rot and death of the plant.

Reasons for Yellowing Leaves of the Ping'an Tree

The main reasons for yellowing or falling leaves of the Ping'an Tree include the following aspects:

1. Due to accidents or special circumstances, the plant's root system is seriously damaged, causing the leaves to turn yellow.

2. When the indoor temperature is below 5°C, cold damage causes the Ping'an Tree to turn yellow and shed leaves.

3. Overwatering causes root rot at the bottom, thereby causing the plant to turn yellow and shed leaves.

4. Water quality is relatively alkaline, causing the leaves to slowly turn yellow. This situation is relatively common in the north, especially in places such as **.

5. Improper fertilization, with too much or too concentrated fertilizer, causes the nutrient fibrous roots to lose water, shrink, and necrose.

6. Long exposure to the scorching sun causes the leaves to dry up and turn yellow.

The method to solve the yellowing of Ping'an Tree leaves is: when yellowing leaves are found on the tree, immediately check whether the root system of the Ping'an Tree is growing normally. If root rot is found, immediately remove the rotten part, cut off the yellow or dead leaves, and replant once.

Cultivation Methods and Precautions for the Ping'an Tree; Precautions for Cultivating the Ping'an Tree

Fertilizing the Ping'an Tree

The Ping'an Tree has quite high fertilizer requirements. From spring to autumn, the Ping'an Tree should be given 1 application of diluted cake fertilizer per month. After entering autumn, 2 consecutive applications of phosphorus and potassium fertilizer are needed. This can increase the plant's cold resistance, promote early lignification of new branches and tender shoots, and enable it to overwinter safely.

After entering winter, all fertilization should be stopped to prevent fertilizer from damaging the plant's root system, causing leaves to turn yellow or wither and fall off.

How to Water the Ping'an Tree

We all know that the Ping'an Tree likes a moist growing environment and is not drought-tolerant. The potting soil should maintain a certain degree of moisture. The frequency of watering is determined according to the season. From the surface, when the topsoil is a little dry, it needs watering.

In dry weather conditions, the leaves need to be sprayed with water. In summer, watering should be maintained once a day. After the Ping'an Tree enters autumn, the amount of watering should be controlled. In winter, more spraying and less watering should be done. If there is standing water in the potting soil, it will cause the plant to turn yellow.

Key Points for Propagating the Ping'an Tree

The Ping'an Tree is mostly propagated by sowing. In southern regions, it is usually sown in rows in trenches from September to October. When the seedlings grow 3 to 4 true leaves, apply liquid fertilizer once a month. Stop fertilizing after autumn, do a good job of cold protection, and overwinter at an indoor temperature of no less than about 5°C.

Pruning Essentials for the Ping'an Tree

Pruning of the Ping'an Tree is carried out in spring. When the temperature is 20°C, prune and shorten some branches to increase the number of branches. The cuts should be smooth, and pinching should be done promptly to promote multiple branch buds and avoid imbalanced growth of the plant. Practice has shown that for Ping'an Trees cultivated in the north, the effect of timely pinching is much better than pruning.

Changing Potting Soil for the Ping'an Tree

During the growing season, potted Ping'an Trees should have their soil loosened once a month to maintain normal root development and keep the root system in a well-aerated state. Small Ping'an Trees can be repotted once a year, while large ones can be repotted once every 2-3 years. During repotting, all necrotic roots should be cut off to ensure normal growth and development of the plant.
