What to do if the leaves of the巴西木 turn yellow
For netizens to explain how to deal with the yellowing of the leaves of巴西木 and the reasons and solutions for the yellowing of巴西木 leaves, here are some experiences in the aspect of green plant maintenance. Next, the editor will introduce.
Reasons and treatment methods for the yellowing of巴西木 leaves
1. Soil and water are too alkaline
The best soil for巴西木 potted plants is a mixture of decomposed leaf soil, cultivation soil, and coarse sand. If the selected soil is not suitable, the soil lacks soluble iron and other elements that can be absorbed by the plant, and the leaves will gradually turn yellow. It is necessary to choose the right soil for planting and often water with aluminum fertilizer solution during growth.
2. Too much watering
巴西木 does not require much water and prefers a high humidity environment, but the potting soil should not be waterlogged to avoid poor ventilation and root rot. Excessive watering can cause the巴西木 potting soil to remain too moist for a long time, leading to soil hypoxia, some fibrous roots rotting, obstructing normal breathing 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 often loosen the soil to ensure good soil aeration.
3. Too little watering
巴西木 requires a higher humidity in the surrounding environment. If the watering of巴西木 is too little and the surrounding air is also dry, it can easily cause the leaves to become dull and lackluster, wilt and droop, and turn yellow and fall off. The solution to this situation is to water a small amount and spray water to gradually restore it before returning to normal watering.
4. Dry air
巴西木 requires a higher humidity in the surrounding environment. If the indoor air is too dry,巴西木 often shows yellowing at the leaf tips. In this case, it is necessary to increase the humidity by methods such as spraying water or covering with a plastic film to provide a better growth environment for巴西木.
5. Insufficient lighting
巴西木 enjoys sunlight. If巴西木 is kept in a shaded or poorly lit area for a long time, it can lead to yellowing of the leaves. It is necessary to move it to a place with sufficient but not strong light for planting.
6. Poor ventilation
If巴西木 is given too much nitrogen fertilizer, the branches and leaves grow too lush, and if not pruned for a long time, the leaves inside the plant will not get enough light, easily causing the leaves to turn yellow and fall off. It is necessary to fertilize reasonably and strengthen pruning to ensure good ventilation and light.
7. Insufficient fertilization
巴西木 needs to continue fertilizing. If no nitrogen fertilizer has been applied for a long time or the potting soil has not been changed, the soil lacks nitrogen and other nutrients, causing the branches and leaves to become weak and the leaves to turn yellow. The solution is to 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 of巴西木
Common pests of巴西木 include leaf spot disease and anthracnose, which can be controlled by spraying 70% methyl thiophanate wettable powder at 1000 times dilution. Pests include scale insects and aphids, which can be controlled by spraying 40% omethoate emulsion at 1000 times dilution.
The above comprehensive introduction about what to do if the leaves of巴西木 turn yellow and the reasons and solutions for the yellowing of巴西木 leaves, hoping to bring some knowledge about green plants to green plant enthusiasts.
