What is the lowest temperature that Euphorbia milii can tolerate in cold weather?
This article introduces the planting content of Euphorbia milii and its lowest cold tolerance temperature. Let's find out more from the editor.
What is the lowest temperature that Euphorbia milii can tolerate in cold weather?
Euphorbia milii has poor cold resistance, with a tolerance temperature of 0 degrees. It can endure temperatures as low as 0 degrees, but if kept in a 0-degree environment for an extended period, it will be frostbitten, resulting in yellowing, blackening, shriveling of the leaves, and other issues, and may even freeze to death. In the south, it can survive outdoors during winter. However, in the north, it must be moved indoors for care or properly insulated to avoid freezing to death.
Euphorbia milii, also known as crown of thorns, is a common potted plant. Its flowers are very beautiful with vibrant colors, though they are small. Let's focus on the lowest cold tolerance temperature of Euphorbia milii.
Is Euphorbia milii cold-tolerant?
Euphorbia milii has poor cold resistance. It can sustain frostbite and death in a 0-degree environment. In the south, it can survive outdoors during winter.
In the north, it must be moved indoors for care or properly insulated to avoid freezing to death. It's best to keep it indoors where the temperature does not drop below 15 degrees to safely survive winter.
The cold tolerance temperature of Euphorbia milii
The cold tolerance temperature of Euphorbia milii is 0 degrees. It can endure temperatures as low as 0 degrees, but if kept in a 0-degree environment for an extended period, it will be frostbitten, resulting in yellowing, blackening, shriveling of the leaves, and other issues, and may even freeze to death.
Therefore, during winter, it is recommended to keep it in a 10-degree environment to induce dormancy.
How to care for Euphorbia milii in winter
1. Expose to light
When growing Euphorbia milii in winter, especially in the north, it's important to move it to a sunny indoor area for more sunlight exposure to raise its temperature and promote healthy growth. Avoid keeping it in a dark place, as this may cause the leaves to turn yellow.
2. Wrap with plastic film
In the south, where the outside temperature is not too low, Euphorbia milii can continue to be grown outdoors but needs to be wrapped in plastic film to raise its temperature.
However, it's important not to keep Euphorbia milii wrapped all the time. To ensure proper ventilation, open the film during the afternoon when the sun is strong to expose it to fresh air, which ensures better winter survival.
3. Control watering and fertilizing
In winter, it's important to control the amount of water and fertilizer for Euphorbia milii, as the low temperature slows down its growth. Excess water only burdens the roots, so watering must be done correctly.
Additionally, excessive fertilizing can damage the plant. The correct approach is to fertilize first, then water after two days, repeating this cycle with a 7-10 day interval.
