What causes the crown of thorns (Euphorbia milii) to drop its leaves?
The crown of thorns (Euphorbia milii) is very common in our daily lives. Its ornamental value is relatively high, which is why it is also very popular with many people. Today, the crown of thorns is mainly grown as a potted plant and is very widely distributed in China. However, when growing the crown of thorns, many problems often arise, and leaf drop is one of them. So what is going on when the crown of thorns drops its leaves? Below, the editor will give you a brief introduction, so let's take a look!
1. Unsuitable soil
The crown of thorns has fairly strict requirements for soil. It likes to grow in soft, nutrient-rich soil. If the soil is too poor and has become compacted and hardened, it is very unfavorable for the growth of the crown of thorns. It will affect the respiration of the roots, and water penetration will also be blocked, causing the crown of thorns to suffer from a lack of nutrients and water and to drop its leaves. Therefore, when growing the crown of thorns, we should loosen the soil regularly and it is best to repot it every year. This creates a good soil environment for the growth of the crown of thorns.
2. Overwatering
The crown of thorns has a fairly strong drought tolerance, so during its growth it does not need much water. Therefore, we must be careful to control the amount of watering. If too much water is given and the soil becomes waterlogged, it will seriously affect the growth of the crown of thorns. The roots are easily drowned, which blocks root respiration and nutrient uptake, and the leaves will also drop. So in normal care, be sure not to water too much. If too much water has been given, pay attention to drainage, improve ventilation, and encourage the water to evaporate as quickly as possible.
3. Insufficient light
The crown of thorns likes to grow in an environment with plenty of light. A sufficiently bright environment is very beneficial for its growth and can also effectively increase the number of flowers it produces. Therefore, if the crown of thorns grows for a long time in a dark, low-light environment and the plant cannot receive enough light, it will also drop its leaves, reducing its ornamental value. So during the growing season, place it in a sunny spot to ensure it gets plenty of light. However, in the strong light of summer, you still need to provide shade to prevent the leaves from being scorched by direct sunlight.
4. Temperature too low
The crown of thorns has very poor cold tolerance, because it is not suited to growing in low-temperature environments. So low temperatures are also a main cause of leaf drop in the crown of thorns, especially in winter. Therefore, before winter arrives, we need to create a warm environment for the crown of thorns and make sure the temperature does not drop below zero. If the temperature cannot be effectively controlled, cover it with a bag, which can also achieve the purpose of keeping it warm, so everyone must pay close attention.
The above is a brief introduction to why the crown of thorns drops its leaves. That is all for today's introduction. This article is for reference only, and we hope it can help you!
