What causes calla lily leaves to turn yellow?
Calla lily is a perennial robust herbaceous plant of the Araceae family. It is distributed throughout various regions of China, and the calla lily has very high ornamental value. Moreover, although the calla lily is toxic, it can also be used as medicine and has the effect of clearing heat and detoxifying. However, many people find that calla lily leaves tend to turn yellow when growing them. So what causes calla lily leaves to turn yellow? Let's take a look together with the editor below!

1. Improper watering
Calla lily likes to grow in a relatively moist environment, but we also need to pay attention to controlling the amount of watering. This is because the calla lily's tolerance to waterlogging is relatively poor. If there is standing water in the soil, then the calla lily's roots will be greatly affected, such as root rot, which causes the calla lily leaves to turn yellow. But it also cannot be short of water; if the soil is too dry, it is easy to cause the calla lily leaves to dry up and turn yellow. Therefore, we need to pay attention to controlling the watering work. If watered too much or after long periods of rain, loosen the soil and drain in time; if the soil is dry, water appropriately to keep the soil moist. When watering, do not pour water into the center of the leaves, to avoid causing soft rot.
2. Improper fertilizing
The calla lily also has a relatively large demand for fertilizer and needs sufficient nutrients to ensure it blooms. But just like watering, if too much fertilizer is applied or the concentration is too high, it is easy to cause fertilizer burn and injure the calla lily's roots. This will naturally cause the calla lily's yellow leaves phenomenon, and if insufficient fertilizer is applied, the calla lily may also develop yellow leaves due to insufficient nutrients. If too much fertilizer has been applied, water in time to flush out the fertilizer, or replace with new soil and rinse the roots. Under the premise of ensuring sufficient growth nutrients for the calla lily, the amount of fertilizer applied must be controlled, and too much fertilizer must not be applied.
3. Unsuitable temperature
The calla lily has relatively high requirements for temperature during growth, and the calla lily likes to grow in a relatively warm environment. Its cold tolerance is very poor, and temperatures that are too high or too low are both very unfavorable to the growth of the calla lily and can also very easily cause the yellow leaves phenomenon. Therefore, we need to pay attention to controlling the temperature well. In the high-temperature season of summer, pay attention to doing a good job of shading to avoid direct strong light. Similarly, in winter, prevent cold and keep warm, to avoid too low a temperature causing the calla lily leaves to freeze and turn yellow.
4. Other reasons
In addition to the above several reasons, poor ventilation is also a main reason causing calla lily leaves to turn yellow. If the calla lily is in a closed environment for a long time, then the air quality becomes poor, and insufficient oxygen content will affect the growth of the entire calla lily plant, causing various phenomena such as yellow leaves. Another point is lighting. The calla lily also has a relatively large demand for light. If there is insufficient light or the light is too strong, then it is very unfavorable to the growth of the calla lily, so everyone must pay a lot of attention.
The above is a brief introduction to what causes calla lily leaves to turn yellow. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
