Does the Fortune Tree Fear Cold?
As a widely popular indoor foliage plant, the cold tolerance of the Fortune Tree often confuses caregivers. Its genetic origin from tropical regions determines its sensitivity to low temperatures, especially requiring special care in seasons with significant day-night temperature differences.
Analysis of the Cold Tolerance of the Fortune Tree
Critical Temperature Tolerance Point
When the ambient temperature drops to 8°C, the Fortune Tree will enter a dormant state, and temperatures continuously below 5°C will cause the leaves to turn yellow and fall off. Special attention is needed in northern regions for sudden cold spells, and in southern areas, avoiding frost areas is necessary for outdoor overwintering.
Manifestations of Frost Injury
Initially, it manifests as curling of the leaf edges and browning of the leaf tips, with severe cases showing transparent frost spots on the branches. If abnormalities are detected, it should be immediately moved to an environment above 15°C, and damaged parts should be pruned to avoid infection by pathogens.
Overwintering System Protection for the Fortune Tree
Nutrition Reserve Management
Apply phosphorus and potassium fertilizers in the late autumn to enhance stress resistance, combined with decomposed sheep manure to improve soil structure. It is recommended to alternate between slow-release fertilizers and liquid fertilizers to establish a long-term nutrient supply mechanism.
Light, Water, and Temperature Synergistic Regulation
Ensure 4 hours of direct sunlight daily during winter, combined with thick curtains to control day-night temperature differences. Use warm water at 25°C for irrigation, combined with ceramic stones on the surface to maintain a stable root microenvironment.
Three-Dimensional Cold Protection Measures
The trunk is wrapped using the "sandwich" method: the inner layer with non-woven fabric absorbs moisture, the middle layer with pearl cotton provides insulation, and the outer layer with waterproof film prevents moisture. Use a humidifier to maintain 40%-60% air humidity to prevent winter dryness damage.
Through scientific temperature management, precise water and fertilizer control, and physical protective measures, it is entirely possible to ensure the Fortune Tree safely overwinters. Regularly observe the plant's condition, adjust the care plan based on environmental parameters, and the green plant will remain vigorous.
