Regional wintering strategies
Colocynth is extremely heat-loving, and any cold temperatures can cause harm to it. In the autumn, it is recommended to bring outdoor-grown Colocynth indoors and place it near a bright window, but it should be kept at a certain distance from heaters. Maintaining temperatures above 20°C during winter is beneficial for plant growth. Any temperatures approaching 5°C are detrimental to the plant.

Signs of Low and High Temperature in Colocynth

Symptoms of Low Temperature in Colocynth
Colocynth prefers warm temperatures and is not tolerant of low temperatures. It thrives best when the temperature is above 20°C. During winter, it should be kept above 5°C. When the temperature falls below 1°C, the leaves may lighten in color. After frost damage, the color gradually turns brown or black, and symptoms such as wilting and drooping may occur.
Solutions for Low Temperature in Colocynth
Trim off the frost-damaged parts. Immediately move indoors to a warm environment for cold protection. Choose a spot near a south-facing window to place the plant, ensuring ample sunlight. Additionally, avoid placing the plant near heaters or air conditioning vents to prevent excessive dryness in the air.
Symptoms of High Temperature in Colocynth
During summer, Colocynth should be kept below 38°C. When the temperature exceeds 43°C, the color of the leaves becomes lighter, and the plant becomes more susceptible to sunburn.
Solutions for High Temperature in Colocynth
Trim away the sunburned and dried-up parts. Move the plant to a location that provides shade from the midday and afternoon sun. Water the plant in the morning and evening to keep the soil moist.
