What causes calla lily leaves to turn yellow

Calla lily is a perennial robust herbaceous plant in the Araceae family. It is distributed throughout China, and calla lily has high ornamental value. Moreover, although calla lily is toxic, it can also be used as medicine and has the effect of clearing heat and detoxifying. However, many people, when growing calla lilies, find that calla lily leaves are prone to yellowing. 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. Because calla lily is still relatively poor in waterlogging tolerance, if there is water accumulating in the soil, then the roots of the calla lily will be greatly affected, such as root rot, causing calla lily leaves to turn yellow. But it also cannot lack water; if the soil is too dry, it is likely to cause calla lily leaves to dry up and turn yellow. Therefore, we need to pay attention to controlling watering work well. If there is too much watering or 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 water into the leaf center, to avoid causing soft rot.

2. Improper fertilizing

Calla lily also has a relatively large demand for fertilizer and needs sufficient nutrients to ensure that the calla lily blooms. But just like watering, if too much fertilizer is applied or the concentration is too high, then fertilizer damage is likely to occur and cause the roots of the calla lily to be injured. Naturally, this will cause the phenomenon of yellow leaves in calla lily, and if fertilization is insufficient, calla lily may also have yellow leaves due to insufficient nutrients. If too much fertilizer is applied, water in time to wash 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 fertilization should be controlled well, and too much fertilizer should not be applied.

3. Unsuitable temperature

Calla lily still has relatively high requirements for temperature during growth, and calla lily likes to grow in a relatively warm environment. Its cold tolerance is very poor, and too high or too low a temperature is very unfavorable to the growth of calla lily, and it is also very prone to the phenomenon of yellow leaves. 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 calla lily leaves to freeze and turn yellow.

4. Other reasons

In addition to the above 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 yellow leaves and various other phenomena. Another point is lighting. Calla lily also has a relatively large demand for light. If the light is insufficient or the light is too strong, then it is very unfavorable to the growth of the calla lily, so everyone must pay much 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!
