What is the lowest temperature that Wisteria can tolerate in the cold
A small knowledge of life, introducing the small knowledge of flower cultivation about the lowest temperature that Wisteria can tolerate in the cold, and the following is a comprehensive introduction.
What is the lowest temperature that Wisteria can tolerate in the cold
Wisteria has strong cold resistance, with a tolerance temperature of minus 12 degrees Celsius. It can tolerate minus 15 degrees Celsius at the lowest. When Wisteria is exposed to minus 15 degrees Celsius for a long time, it will be frostbitten or even frozen to death. In southern regions, it can be maintained outdoors without special temperature control. If Wisteria is maintained in the cold northern regions, it is best to move it indoors.
Wisteria is also known as the "itchy tree" or "startle tree," and is a deciduous tree. Wisteria prefers to grow in sunny areas with warm and humid climates, which promote better growth.
Is Wisteria cold-tolerant?
Wisteria has strong cold resistance and can withstand temperatures as low as minus 10 degrees Celsius. If Wisteria is maintained in southern regions, it can be kept outdoors without special temperature control.
If Wisteria is maintained in the cold northern regions, it is best to move it indoors for maintenance. Note that it is sufficient to ensure that the temperature in the Wisteria maintenance environment is between 0-5 degrees Celsius.
The cold tolerance temperature of Wisteria
The cold tolerance temperature of Wisteria is minus 12 degrees Celsius, with the lowest tolerance of minus 15 degrees Celsius. When Wisteria is exposed to minus 15 degrees Celsius for a long time, it will be frostbitten or even frozen to death.
The most suitable temperature range for Wisteria growth is 15-40 degrees Celsius. Different varieties of Wisteria can tolerate different minimum temperatures. Common Wisteria can tolerate temperatures as low as minus 10 degrees Celsius, while the Japanese maple-leaf Wisteria can tolerate temperatures as low as minus 23 degrees Celsius.
How to overwinter potted Wisteria
1. Temperature
When cultivating Wisteria in winter, it is important to adjust the temperature. Young seedlings have poor cold resistance and need proper protection from the cold. Do not place Wisteria in an environment below five degrees Celsius, or it may die from low temperatures.
Once mature, Wisteria plants have stronger cold resistance, and保温 can be stopped after three years of growth.
2. Water and Fertilizer
Wisteria is drought-resistant and dislikes waterlogging. It can be watered once before sprouting in spring and once after defoliation in autumn. At other times, follow the principle of "no watering when not dry." Additionally, in winter, attention should be paid to the management of water and fertilizer for Wisteria, with one application of fertilizer after defoliation in autumn.
Fertilization should be stopped in winter because Wisteria is dormant and has low requirements for water and fertilizer. Excessive application can lead to the death of Wisteria.
3. Pruning
In winter, Wisteria enters dormancy, and pruning should be done after the dormancy period to ensure its shape.
During the pruning process, the branches should be pruned to have a layered look to avoid crossing over each other and to ensure a layered appearance, with only a few buds left on the main stem.
Sick and dry branches, overlapping branches, and too dense branches can be cut off, leaving about 10 centimeters of old branches.
The above shares the full content of the lowest temperature that Wisteria can tolerate in the cold. I hope it can help you, and I also hope everyone comes to see more green plant and flower experience knowledge!
