The reason for the color change of succulents in cold weather is related to the low temperature.

Reasons for Color Change in Succulents in Cold Weather

Do you know these? Here are experiences in the aspect of green plant maintenance regarding the reasons for the color change in succulents during cold weather, with detailed introduction below.

Reasons for Color Change in Succulents in Cold Weather

Succulents have thick and juicy leaves, with their own nutritional organs rich in water content, making them drought-resistant and dislike积水. An overly humid environment can easily lead to excessive growth and root rot. Therefore, the cool and dry environment of autumn and winter is beneficial for reducing the water concentration within cells. When the pigment concentration is relatively high, the colorimetric reaction is more pronounced.

Why Succulents Look Better in Cold Weather

Actually, many succulents are quite cold-tolerant. As long as we move them indoors for maintenance and ensure proper insulation, the plants will grow very vigorously. The leaves are thick and colorful during winter, making them look more attractive.

Sufficient Sunlight

In autumn and winter, the weather is dry and the sunlight is abundant. Sunlight is the primary driving force for photosynthesis in succulents, which helps in nutrient production and water evaporation.

While reducing the water concentration, it increases the concentration of pigments and sugar alcohols in succulents, thereby causing a colorimetric reaction.

Air Dryness

Succulent leaves are thick and juicy, with their own nutritional organs rich in water content, making them drought-resistant and dislike积水. An overly humid environment can easily lead to excessive growth and root rot.

Therefore, the cool and dry environment of autumn and winter is beneficial for reducing the water concentration within cells. When the pigment concentration is relatively high, the colorimetric reaction is more pronounced.

Large Temperature Differences

Temperature difference mainly refers to the difference between day and night. The large temperature difference in autumn and winter is favorable for succulents to fully perform photosynthesis and produce nutrients during the day, while the low temperature environment at night helps reduce evapotranspiration and avoid excessive nutrient consumption.

The temperature difference effect brought by day and night temperatures is also a catalyst for the thickening of succulent leaves, the increase in powdery substances, and the obvious coloring effect.

In autumn and winter, to prevent the lowest night temperature from dropping below zero, controlling the day and night temperature difference at around 10℃ is optimal! For example, keeping it above 15℃ during the day and not below 5℃ at night.

Compared to the hot summer, when succulents are prone to black rot and waterlogging, they can grow well in the cool autumn and winter.

Besides the well-known spring and autumn seasons, the early winter season is also a golden period for the growth of succulents, making it a relatively easy time to achieve good conditions!
