How to remedy the situation when the leaves of Phoebe nanmu suddenly dry up and fall off?

Red nanmu , also known as fish scale wood, is a shrub of the genus Syzygium in the Myrtaceae family. Its young branches have edges and turn dark brown when dry. The tree of red nanmu has an upright and graceful posture, and its leaves are slender and green. It has a high ornamental value and is often cultivated as a potted plant . So how to remedy the situation when the leaves of red nanmu suddenly dry up and fall off? Let’s take a look below.

1. How to remedy the situation when the leaves of red nanmu suddenly dry up and fall off?

1. Water regularly

The drying and falling leaves of red nanmu may be caused by not watering for a long time. If the plant does not have enough water, it will reduce water evaporation by dropping leaves. When this phenomenon occurs, it is necessary to replenish water to the plant in time, and sprinkle water around it to increase the air humidity. With careful maintenance for a period of time, the red nanmu will return to normal.

2. Stay warm

Red nanmu likes to grow in a warm environment. The most suitable temperature for its growth is between 20-30℃. If the temperature is too high or too low, its leaves will dry up and fall off. During daily maintenance, you must take temperature control measures. Place it in a cool place in summer and move it to a warm place indoors in winter.

3. Change pots regularly

When growing red nanmu, the potting soil needs to be replaced every 1-2 years to prevent the soil from becoming compacted. If the soil is not changed for a long time, the red nanmu may dry up and drop leaves. If this happens, you can replace the plant with loose, breathable, and well-drained soil in time, which can improve the phenomenon of red nanmu dropping leaves.

2. Cultivation methods and precautions of red nanmu

1. Placement: Red nanmu is shade-tolerant and can be placed in a semi-shaded environment. It needs to be shaded in summer or placed under the shade of trees. It can be placed indoors in winter.

2. Watering: The soil in the pot should maintain a certain humidity, but water should not accumulate. Water frequently during the growing season in spring and summer, water once in the morning and evening during the hot summer days, reduce the amount of watering after autumn, and keep the soil in the pot moist in winter.

3. Fertilization: During the growing season, apply thin, decomposed cake fertilizer water every 20 days or so, and apply alum fertilizer water appropriately to keep the branches and leaves lush and the leaves bright green; in winter, only apply base fertilizer once.

4. Pruning: Red nanmu has strong germination ability and is very resistant to pruning. You can prune unnecessary long branches, crossed branches and overlapping branches at any time, and remove excess buds to maintain the beautiful shape of the tree.

5. Repotting: Repot every 2 to 3 years, preferably between February and March in spring, or after autumn. In conjunction with repotting, trim some old roots, replace the 1B2 old soil, and cover it with loose and fertile new potting soil.

6. Pest and disease control: Red nanmu has very few pests and diseases. Occasionally, scale insects may cause damage. You can spray 1500-2000 times diluted 80% DDT for prevention and control, or you can use a brush to brush off the insects.
