I. Basic information about the Ping'an Tree

1. Introduction to the Ping'an Tree

The Ping'an Tree is also called Lanyu cinnamon, Hongtouyu cinnamon, Hongtoushan cinnamon, large-leaf cinnamon, and Taiwan cinnamon. It is an evergreen small tree of the genus Cinnamomum in the family Lauraceae, native to Lanyu Island in Taiwan, China.

2. Morphological characteristics of the Ping'an Tree

The Ping'an Tree has upright branches and stems that are yellow-green, smooth and without fuzz; the leaves are relatively large, opposite or nearly opposite, generally 10 cm-22 cm long and 5 cm-8 cm wide. The upper surface of the leaves is bright green with a metallic-like sheen, while the underside is grayish green; the fruit of the Ping'an Tree is egg-shaped and spherical, with a cup-shaped fruit receptacle whose margin has short rounded teeth.

3. Uses of the Ping'an Tree

The Ping'an Tree has many cultivation uses: it is both a beautiful potted landscape plant and a very attractive garden tree. In addition, it also purifies indoor air and absorbs renovation pollution.

II. Cultivation methods and precautions for the Ping'an Tree

To learn how to grow the Ping'an Tree, you must first provide it with suitable soil and appropriate light, master the correct watering and fertilizing methods, and also prune it regularly during routine care. For the specific cultivation methods and precautions, please read on:

1. Potting soil requirements

The Ping'an Tree likes loose, breathable, well-drained, fertile acidic culture soil or leaf mold rich in organic matter. Sticky soil must not be used, otherwise it easily causes root rot; for the flowerpot, choose a ceramic pot suitable for the plant's growth according to the size of the plant, and also make sure the bottom has drainage holes.

2. Temperature requirements

The suitable growth temperature for the Ping'an Tree is 20-30°C. Its cold resistance is relatively weak, and small trees are not tolerant of low temperatures. Low temperatures below 0°C easily cause the bark to freeze and crack and the branches and leaves to wither, and small trees will freeze to death roots and all. Household potted plants should maintain a room temperature of about 10°C to overwinter, so that the Ping'an Tree can always stay green. Larger plants can endure short periods of low temperature around 0°C indoors when there is no cold wind blowing on them; after summer temperatures exceed 32°C, shade with a shed and spray water on the leaves to increase humidity and lower temperature, so that it can maintain vigorous growth.

3. Light requirements

The Ping'an Tree is a light-loving plant, but it is also fairly shade-tolerant. However, the Ping'an Tree has different light requirements at each growth stage. When young, it is shade-tolerant, and 3-5 year old plants grow faster under shaded conditions; 6-10 year old plants require fairly sufficient sunlight; after entering summer, avoid direct sun exposure. As the hot season arrives, shading treatment is needed, or it should be moved indoors for cultivation.

4. Water requirements

The Ping'an Tree likes a moist environment. Potted plants should keep the potting soil moist at all times, but there must be no water accumulation, otherwise it easily leads to root rot; during the peak growth seasons of spring and autumn, water frequently to keep the potting soil moist, and you can also often spray water on the leaves to maintain air humidity. After autumn begins, watering should be controlled; in winter, spray more and water less, and you can wait until about half of the potting soil is dry before watering.

5. Fertilization requirements

The Ping'an Tree fairly likes fertilizer. From spring to autumn during the growing season, it needs to be fertilized once every month, with household decomposed cake fertilizer or compound fertilizer. After entering autumn, apply phosphorus and potassium fertilizer to ensure the plant can overwinter safely. In winter, stop fertilizing to avoid harming the plant.

6. Pruning requirements

The Ping'an Tree should be pruned when it is too dense. The Ping'an Tree can be pruned in all four seasons, but the most suitable time is clear weather in spring and autumn, because at this time the Ping'an Tree is in its growth period and easily sprouts new branches after pruning. It is recommended to cut off diseased branches and weak, thin branches and shorten long branches. When the plant is relatively small, pinching can be done to promote branching.

7. Loosening the soil and repotting

For the Ping'an Tree's potting soil, it is recommended to loosen the soil once a month to keep the soil loose and prevent soil compaction from causing poor growth of the Ping'an Tree. When loosening the soil, be careful not to damage the plant's roots. Small Ping'an Trees should be repotted once a year, and large ones on average once every 2-3 years.

Note: Ping'an Trees grown outdoors must be kept from rain. During the rainy season, promptly move the Ping'an Tree indoors to a ventilated place for care, so as to avoid water accumulating in the flowerpot.

III. What to do if the Ping'an Tree's leaves turn yellow and fall off?

Beginners always encounter some problems when growing the Ping'an Tree, such as leaves turning yellow and falling off. Below is an introduction to the causes and solutions for yellowing, falling leaves of the Ping'an Tree:

1. Temporary potted plant: Many potted plants just bought back have just been transplanted from the ground, and if later care is improper, yellowing leaves will appear.

Solution: Generally, newly bought Ping'an Trees will show some degree of yellow leaves because of the change in growing environment. At this time, place it in a cool, ventilated place for a week, then gradually expose it to light.

2. Improper watering: Usually watering the Ping'an Tree too much will cause water accumulation in the soil, and the excess water cannot evaporate quickly. Over time, too much water will cause the leaves to turn yellow.

Solution: Usually control the watering frequency well and water an appropriate amount according to the dryness and moisture of the potting soil. At the same time, choose breathable soil. If you have already watered too much, put the flowerpot in a ventilated spot and let the wind dry the soil, then reduce the watering frequency.

3. Too little soil: Some merchants, in order to save costs, do not use good soil to grow Ping'an Trees. Some sellers, to save soil, support the bottom with foam. Over time, this restricts the development of the Ping'an Tree's root system, and then yellowing and withering leaves appear.

Solution: Reselect fertile, breathable soil with sufficient nutrients, then replant.

4. Improper temperature: In winter, when the temperature is relatively low, if it is not kept warm in time, especially if placed outdoors below 5°C, its leaves may be frostbitten and thus turn yellow.

Solution: In winter, the Money Tree should be moved indoors for care, and the temperature should be kept above 10°C, with watering frequency reduced. If it has already been frostbitten, remove the yellow leaves and provide it with a warm growing environment.

5. Improper light: Summer light is strong. If the Ping'an Tree is exposed to strong sun outdoors for a long time, it may scorch its leaves and also cause the leaves to lose water and turn yellow.

Solution: In summer, shading treatment is needed. If it has already been scorched, move it indoors for cultivation, remove the yellowed leaves, and care for it slowly.

In addition to the situations above, it may also be affected by factors such as improper fertilization, water that is too alkaline, plant diseases, and an unsuitable growing environment. The specific cause of yellow leaves should be determined according to the actual situation, and then an appropriate remedy should be chosen.

Conclusion: The cultivation methods and precautions for the Ping'an Tree are introduced here. As long as you understand the plant's growth characteristics, you can grow it well. We hope that through the methods above you can grow a lush, green Ping'an Tree.
