Euphorbia cyathophora, also known as "Green Euphorbia麒麟," is an indoor plant with very high ornamental value. Recently, many flower enthusiasts have reported that the leaves of Euphorbia cyathophora have turned yellow, which has caused many enthusiasts to be troubled. This article will provide a detailed analysis of the reasons for the yellowing of Euphorbia cyathophora leaves and solutions.
Reasons for the yellowing of Euphorbia cyathophora leaves1. Insufficient light
Euphorbia cyathophora prefers scattered light. If it is in a dark environment for a long time, it will cause the leaves to turn yellow. In the daily maintenance process, it should be ensured that Euphorbia cyathophora receives sufficient scattered light.
2. Improper watering
Watering is a crucial aspect of Euphorbia cyathophora maintenance. Excessive or insufficient watering can cause the leaves to turn yellow. Excessive watering can lead to root hypoxia, affecting plant growth, while insufficient watering will cause the leaves to lack water, resulting in yellowing.
3. Soil problems
Soil that is too heavy or compacted can prevent the roots from breathing properly, thus affecting plant growth and causing the leaves to turn yellow. High salt content in the soil can also harm Euphorbia cyathophora.
4. Improper fertilization
Excessive or improper fertilization can cause Euphorbia cyathophora leaves to turn yellow. Too much fertilization can increase the salt concentration in the soil, preventing the roots from absorbing nutrients, which leads to yellowing leaves.
5. Pest and disease infections
Euphorbia cyathophora is prone to pest and disease infections, such as aphids and red spiders. These pests can cause the leaves to turn yellow and, in severe cases, even lead to plant death.
Solutions to the yellowing of Euphorbia cyathophora leaves1. Adjusting light
Place Euphorbia cyathophora in a location with sufficient scattered light and avoid long periods of exposure to dark environments. If indoor lighting is insufficient, desk lamps or plant growth lights can be used for auxiliary illumination.
2. Controlling watering
Based on Euphorbia cyathophora's growth habits, keep the soil slightly moist. If excessive watering occurs, promptly pour out the excess water to avoid root hypoxia. If insufficient watering occurs, increase the watering frequency appropriately.
3. Improving soil conditions
Replace the soil with loose, breathable, and well-draining options like decomposed leaf soil or sandy soil, and regularly loosen the soil to promote root respiration.
4. Reasonable fertilization
When fertilizing, follow the principle of "frequent application of thin fertilizer." Choose fertilizers suitable for Euphorbia cyathophora, such as nitrogen-phosphorus-potassium compound fertilizers. After fertilizing, keep the soil moist.
5. Preventing and controlling pests and diseases
Regularly inspect Euphorbia cyathophora and take timely measures when pests or diseases are found. Pesticides and fungicides can be used for prevention and control, while maintaining indoor ventilation to reduce the incidence of pests and diseases.
There are many reasons for the yellowing of Euphorbia cyathophora leaves, including insufficient light, improper watering, soil problems, improper fertilization, and pest and disease infections. Understanding these reasons allows us to take appropriate measures to improve the growth conditions of Euphorbia cyathophora. It is hoped that this article can provide assistance to the majority of flower enthusiasts.
