Why do Aspidistra leaves turn yellow?
Aspidistra is also called large-leaf evergreen, bamboo-leaf tray, etc. It is a plant of the Liliaceae family. It has very high ornamental value, and the rhizome of Aspidistra can also be used as medicine. It is also very widely used in our country, with the effects of promoting blood circulation, dispersing blood stasis, tonifying deficiency and relieving cough. However, when we grow Aspidistra, yellowing leaves often occur. So why do Aspidistra leaves turn yellow? Let's take a look together with the editor below!
1. Lighting reasons
Light is very important for the growth of Aspidistra. Suitable light can promote photosynthesis in the leaves of Aspidistra and improve its ornamental value. But the light must never be too strong, because the leaves of Aspidistra are very intolerant of direct sunlight. If exposed to strong direct sunlight, the leaves will be scorched and yellow leaves will appear. Therefore, we should pay attention to maintaining a scattered-light environment, cut off the scorched leaves, and then water appropriately. In strong-light environments such as summer, shading work must be done well to ensure the normal growth of Aspidistra.
2. Overwatering
Aspidistra has a relatively large demand for water and likes to grow in a relatively moist environment. But we must also pay attention to controlling the amount of watering and must not water too much. If excessive watering causes water accumulation in the pot, it will seriously inhibit the respiration of the Aspidistra roots. This will cause yellow leaves. We should maintain good soil permeability, do regular loosening of the soil, drain promptly if there is too much watering, and do a good job of rain protection during the rainy season. When watering, the principle of watering when dry and stopping when wet should be followed. While ensuring sufficient water for the growth of Aspidistra, water accumulation must not occur.
⟦NL>3. Excessive fertilization
Aspidistra has a relatively strong growth ability, so during the growth of Aspidistra, the demand for fertilizer is not very large. Therefore, many flower growers do not control the amount of fertilizer when fertilizing, and it is often easy to apply too much fertilizer, causing fertilizer damage to Aspidistra and the phenomenon of root burning. The leaves will also turn yellow because of fertilizer damage and root burning. If too much fertilizer is applied, the fertilizer should be flushed out promptly with a large amount of water to dilute the concentration. For plants with fertilizer damage, the plant should be taken out promptly, the rotten roots cut off, disinfected, and then replanted in new soil.
4. Pest damage
When cultivating Aspidistra, although Aspidistra has strong disease resistance. It is susceptible to pests such as red spider mites. Red spider mites mainly harm the leaves of Aspidistra, sucking the sap of the leaves and causing the leaves to turn yellow. Therefore, we should do a good job in pest control and regularly spray insecticides to kill insects. And we should often observe both sides of the plant leaves, wipe the leaves with clean water, and keep the leaves in a clean and glossy state, which can also achieve the purpose of preventing pests.
The above is a brief introduction to why Aspidistra leaves turn yellow. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
