Why is my Crown of Thorns dropping leaves? Cause analysis
Crown of Thorns (Euphorbia milii) is very common in our daily life. Crown of Thorns has relatively high ornamental value, so it is also welcomed by many people. Crown of Thorns is now mainly grown as a potted plant and is widely distributed in our country. However, when cultivating Crown of Thorns, many problems often arise, and one of them is leaf drop. So why does Crown of Thorns drop its leaves? Below, the editor will briefly introduce it to you, let's take a look!
1. Unsuitable soil
Crown of Thorns has relatively strict requirements for soil. Crown of Thorns likes to grow in soft soil with sufficient fertility. If the soil is too poor and has become compacted and hardened, then it is very unfavorable for the growth of Crown of Thorns. It will affect the respiration of the roots of Crown of Thorns, and water penetration will also be hindered, thereby causing Crown of Thorns to suffer from a lack of fertilizer and water and to drop leaves. Therefore, when cultivating Crown of Thorns, we should pay attention to loosening the soil regularly, and it is best to repot every year. Create a good soil environment for the growth of Crown of Thorns.
2. Overwatering
Crown of Thorns has relatively strong drought tolerance, so during its growth it does not need much water. Therefore, we must pay attention to controlling the amount of watering. If too much water is given and water accumulates in the soil, it will seriously affect the growth of Crown of Thorns. The roots are easily flooded, causing the respiration and nutrient absorption of the roots of Crown of Thorns to be hindered, and the leaves will also fall off. Therefore, usually be sure not to water too much. If too much water is given, then pay attention to doing a good job of drainage, strengthen ventilation, and promote the evaporation of water as soon as possible.
3. Insufficient light
Crown of Thorns likes to grow in an environment with sufficient light. An environment with sufficient light is very favorable for the growth of Crown of Thorns, and can also effectively increase the flowering amount of Crown of Thorns. Therefore, if Crown of Thorns grows for a long time in a dark and low-light environment, and the plant cannot receive enough light, then it will also cause Crown of Thorns to drop leaves, leading to a decline in the ornamental value of Crown of Thorns. Therefore, during the growth period of Crown of Thorns, place it in a sunny spot to ensure that Crown of Thorns receives sufficient light. However, in the strong light environment of summer, shading work still needs to be done well to avoid leaves being sunburned by direct strong light.
4. Temperature too low
Crown of Thorns has very poor cold tolerance, because it is not suitable for growing in a low-temperature environment. So low temperature is also one of the main reasons causing Crown of Thorns to drop leaves, especially in winter. Therefore, before winter arrives, we need to create a warm environment for Crown of Thorns and ensure the temperature is not lower than zero degrees. If the temperature cannot be effectively controlled, then cover it with a bag, which can also achieve the purpose of keeping it warm, so everyone must pay more attention.
The above is a brief introduction to why Crown of Thorns drops leaves. That's all for today's introduction. This article is for reference only, and I hope it can help everyone!
