Garlic chive is a common green plant that is deeply loved by people. It can be used not only to cook delicious food but also to enjoy beautiful flowers. Many garlic chive enthusiasts are concerned about its cold tolerance, especially in the colder northern climate. This requires understanding the cold tolerance and care techniques of garlic chives to ensure they can survive the winter healthily.
I. Cold Tolerance Temperature of Garlic Chives
Garlic chives have strong cold tolerance in suitable growing environments, but they are susceptible to frost damage under adverse environmental factors such as excessively low temperatures and high humidity. Generally, the minimum suitable growing temperature for garlic chives is around 5°C. However, the low temperature they can tolerate varies by variety, and some varieties can even survive in temperatures below -10°C.
II. Cold Tolerance Mechanism of Garlic Chives
The reason garlic chives can adapt to low-temperature environments is closely related to their unique physiological mechanisms. In low-temperature environments, garlic chives produce cold-tolerant proteins. These proteins help the plant cope with low temperatures, protect cells from frost damage, and decompose rapidly in high-temperature environments.
III. Care Techniques for Garlic Chives
