Osmanthus can tolerate cold down to the minimum temperature, the limit of cold resistance for Osmanthus.

Cassia Tolerance to Low Temperature

This article provides an introduction to the topic of the minimum temperature that cassia can tolerate in cold conditions. Let's follow the editor to see the specific content!

Cassia Tolerance to Low Temperature

Cassia is not very cold-tolerant, with a cold tolerance temperature of 0 degrees Celsius. It can endure temperatures as low as minus 13 degrees. If the temperature of the environment in which cassia grows drops below minus 13 degrees, it will freeze to death. Cassia can be planted directly in the ground to overwinter in areas south of the Yellow River. In the north, however, it cannot be left outside during the winter. If left outside, it is prone to freezing and death.

In areas south of the Yellow River, cassia can be planted directly in the ground to overwinter. For potted plants, they should be moved indoors during the winter, placed in a sunny location to ensure they receive plenty of direct sunlight. The indoor temperature should be maintained above 5 degrees Celsius, and normal care should be provided.

Cassia Cold Tolerance Temperature

Cassia is not very cold-tolerant, with a cold tolerance temperature of 0 degrees, and can endure temperatures as low as minus 13 degrees. If the temperature of the environment in which cassia grows drops below minus 13 degrees, it will freeze to death.

Can cassia overwinter outdoors?

In the north, cassia cannot be left outside during the winter. Because the winter climate in the north is quite cold, with temperatures commonly reaching minus ten to fifteen degrees. If left outside, it is prone to freezing and death.

Key Points for Cassia Overwintering

1. Appropriate Insulation

Cassia trees have a certain degree of cold tolerance and can overwinter outdoors in the southern regions. In the north, you can wrap the branches and trunks with straw or other insulating materials. For trees planted in the ground, they can be moved indoors for care, keeping the temperature between 5-10 degrees Celsius.

2. Control Watering

Cassia trees are not tolerant of waterlogging, and excessive moisture can lead to root rot. With the low temperatures in winter, moisture evaporates slowly, so to ensure its safe passage through winter, it is necessary to control watering. It is best to water only when the soil is dry, and the water temperature should be almost the same as the room temperature.

3. Stop Fertilizing

If you want cassia trees to safely overwinter, you should also stop fertilizing at this time. No fertilizer should be applied, as this could lead to an excess of nutrients in the soil, causing fertilizer damage to the plant. Generally, applying a matured cake fertilizer or organic fertilizer once before winter is sufficient to meet its growth needs.

4. Sufficient Light

Cassia trees are sun-loving plants. To ensure their safe overwintering, they need to be placed in a well-lit area with plenty of sunlight. If they are kept in the shade for an extended period, the lack of light will cause the branches and leaves to become sparse and weak.
