How to save the yellowing and wilting leaves of the巴西木 (Brazillian Wood)
Today's experience sharing: Learn how to save the yellowing and wilting leaves of the Brazillian Wood and the experience of plant maintenance related to the reasons for yellowing leaves and solutions. Let's understand these together below.
Reasons for the yellowing of Brazillian Wood leaves and treatment methods
1. Soil and water are too alkaline
Brazillian Wood potted plants prefer a mixture of decomposed leaf soil, cultivation soil, and coarse sand. If the chosen soil is not suitable, the lack of soluble iron and other absorbable elements in the soil will cause the leaves to turn yellow gradually. It is important to choose the right soil for planting and to water with iron sulfate regularly during the growing period.
2. Overwatering
Brazillian Wood does not require much water and prefers a high humidity environment, but the soil in the pot should not be waterlogged to avoid poor ventilation and root rot. Excessive watering can cause the soil to remain moist for a long time, leading to oxygen deficiency in the soil, some fibrous roots to rot, and hindering normal respiration and the absorption of water and nutrients, causing the leaves to turn yellow and fall off. The solution to this situation is to immediately control watering, pause fertilization, and frequently loosen the soil to ensure good soil aeration.
3. Insufficient watering
Brazillian Wood has a high requirement for the humidity of the surrounding environment. If the watering is too little and the surrounding air is dry, it can easily cause the leaves to become dull and lackluster, wilt, and turn yellow and fall off. The solution to this situation is to water a small amount and spray water, allowing it to gradually recover before returning to normal watering.
4. Dry air
Brazillian Wood requires a higher humidity in the surrounding environment. If the indoor air is too dry, the leaves of the Brazillian Wood may show yellowing at the tips. In this case, it is important to increase the humidity by methods such as spraying water or covering with a plastic film to provide a better humid environment for the plant to grow.
5. Insufficient lighting
Brazillian Wood enjoys sunlight. If the plant is kept in a shaded or poorly lit area for a long time, it can cause the leaves to turn yellow. The plant should be moved to a place with sufficient but not intense light.
6. Poor ventilation
If Brazillian Wood is fertilized with too much nitrogen and the branches and leaves grow too densely, combined with long-term lack of pruning, it can easily cause the inner leaves to lack light, leading to yellowing and falling off. Reasonable fertilization and pruning should be applied to ensure good ventilation and light.
7. Insufficient fertilization
Brazillian Wood needs to continue fertilizing. If no nitrogen fertilizer has been applied for a long time or the pot has not been changed, the lack of nitrogen and other nutrients in the soil can lead to weak branches and leaves, and yellowing leaves. The solution is to promptly change to new loose and fertile cultivation soil and gradually apply diluted decomposed liquid fertilizer or compound flower fertilizer.
Prevention and control of diseases and pests in Brazillian Wood
Common pests and diseases of Brazillian Wood include leaf spot and anthracnose, which can be controlled by spraying 70% methyl thiophanate wettable powder at a concentration of 1000 times. Pests such as scale insects and aphids can be controlled by spraying 40% omethoate emulsion at a concentration of 1000 times.
