How to save the red nanmu when its leaves have dried up and fallen off?

If the leaves of the red nanmu are not seriously dry, it can still be saved, but if the leaves are dead in a large area, it is very likely that it cannot be saved. The main reason for the leaves of red nanmu to dry up and fall off is generally due to lack of water. Red nanmu is a moisture-loving plant, and leaves will fall if there is insufficient water. Pay attention to replenishing water. In addition, it may also be caused by root damage. The plant can be saved by removing it from the pot in time, pruning off the rotten roots, and replanting it in the pot.

How to care for and manage red nanmu?

1. Pot soil

Red nanmu likes a warm and humid growing environment, and the soil in the pot should be loose and breathable. The soil requirements are different at different stages. It is best to use sandy soil in the embryo stage; for mature stumps or transplanting to pots, it is recommended to use a mixture of leaf mold and sandy soil as the substrate, or peat soil mixed with sand for cultivation.

2. Watering

Red nanmu is a cold-resistant and slightly water-resistant tree species. In the details of daily watering, you can follow the principle of "water when dry, and water thoroughly when watering". During the growing season and summer, you can spray water on the branches and leaves to create humidity, and at the same time increase the frequency of watering to avoid water shortage caused by excessive evaporation. As the temperature drops in winter, it is recommended to reduce the frequency of watering.

3. Fertilization

It is not recommended to apply fertilizer to red nanmu in the first year of cultivation, because the newly cultivated seedlings are delicate and fertilization may burn the stumps. After the spring of the second year, you can apply top dressing. Depending on the growth of the plant, you can apply thin layers of nitrogen and potassium fertilizers every month or so during the growing season.

4. Pruning

After growing the red nanmu for one year, it will have lush branches and leaves. In the second year, you can start to tie up the branches and then prune them.

5. Lighting

Red nanmu needs light and ventilation. After acclimatization, the light exposure time in the morning and evening should not be less than 4-6 hours, and there should be smooth ventilation. In summer, 60%-80% shade should be provided. In winter, plants in the south of the Yangtze River can overwinter outdoors in a sunny and windless place, while plants in North China need to be brought indoors. Remember to keep the room ventilated when keeping warm, and it is taboo to close doors and windows for red nanmu.
