Amaranthus is a common indoor ornamental plant. However, in winter, we may find that its leaves gradually turn yellow. Why do the leaves of asparagus yellow in winter? How to effectively deal with the problem of yellowing of asparagus leaves?
1. Unsuitable lighting 1. The sunshine is weak in winter, and one of the reasons why the leaves of asparagus officinalis are yellowed is insufficient light, which affects photosynthesis.
2. Solution: Place the asparagus in a sunny location, such as next to a window, so that it can fully absorb the nutrients from the sun.
2. Excessive watering 3. The growth rate of winterwood is slow in winter. Excessive watering can easily cause root system rot and cause yellowing of leaves.
4. Solution: Reduce the frequency of watering in winter and ensure that the soil is moderately moist rather than excessively wet.
3. The temperature is too low. 5. Wenzhu likes a warm environment. Low temperatures will affect its normal growth and cause the leaves to yellowing.
6. Solution: Maintain a suitable indoor temperature and do not expose the asparagus to the cold environment.
4. Dry air 7. Lower indoor air humidity in winter will cause the leaves of winterwort to lose moisture and turn yellow and wither.
8. Solution: Increase the humidity of indoor air by spraying water, placing a basin or using a humidifier to increase the humidity.
5. Nutrient deficiency 9. In winter, the growth of asparagus is slow and prone to nutrient deficiency, causing the leaves to turn yellow.
10. Solution: Apply appropriate amount of fertilizer, choose special indoor plant fertilizer, and follow the instructions to apply fertilizer.
6. Invasion of pests 11. The yellowing of the leaves of winterwood may also be due to insect attacks, such as aphids, red spiders, etc.
12. Solution: Identify pests in time and take corresponding control measures, such as spraying with organic pesticides.
7. Infection of bacteria 13. The humid and cold environment in winter can easily breed bacteria, which in turn infect the asparagus, causing yellowing of the leaves.
14. Solution: Regularly check for diseases in the asparagus bamboo, and take timely measures once found, such as cutting off infected parts and appropriately applying fungicides.
The yellowing of the leaves of asparagus bungeanum in winter may be caused by insufficient light, excessive watering, too low temperature, dry air, nutrient deficiency, insect invasion and bacterial infection. Corresponding nursing methods can be taken for different reasons to solve this problem and maintain the healthy growth of asparagus.
