How to Help Million Bells Survive Winter
As a star plant that bursts into bloom on balconies, the winter care and leaf health management of Million Bells are the most concerning issues for flower enthusiasts. This article will systematically analyze the key points of care from winter protection to handling leaf abnormalities, helping you create a sea of evergreen bell flowers throughout the year.
Complete Guide to Winter Care for Million Bells
Accurate Pruning to Control Plant Shape
Perform shaping pruning before the first frost, leaving 15-20 cm of the main branches, removing weak and crossed branches. Focus on retaining 3-4 buds at the base, and apply wood ash after pruning to prevent infection, which can reduce nutrient consumption by 30%.
Temperature Gradient Management Method
In the northern regions, indoor wintering is necessary, maintaining a slow recovery temperature of 5-10°C; in the Yangtze River Valley, outdoor mulching can be used with three layers of protection: earthing the roots + wrapping the branches + sheltering the top. Emergency indoor transfer is needed when the temperature continuously drops below -3°C.
Light and Water Regulation
Ensure 4 hours of direct sunlight daily in winter, adopt the "wet and dry" watering method, and maintain pot soil moisture at 40%-50%. Use a thermometer to monitor the cultivation environment, avoiding a day-night temperature difference greater than 15°C.

Handling Water Imbalance
Basal leaf wilting is often caused by abnormal wet-dry cycles: use the "morning immersion method" to water in summer, and switch to the "noon misting method" in winter. When wilted, first loosen the soil, then water thoroughly, and enhance aeration by using ceramsite mulch.
Light Adaptation Plan
Full sun in spring and autumn, and 50% shading from 10-15 pm in summer. When sunburn spots appear, immediately move to a diffused light environment, cut off the damaged leaves, and use rapeseed hormone at 2000 times dilution to repair.
Disease Prevention and Control System
Focus on preventing and treating leaf spot and gray mold diseases, alternating the use of mancozeb and tebuconazole every month. Immediately remove diseased leaves and spray the underside of leaves with a garlic extract (1:10) to prevent the spread.
Through scientific care and management, Million Bells can not only survive the winter safely but also bloom throughout the year. It is recommended to establish a care log to record temperature and humidity changes and plant responses, gradually forming a personalized cultivation plan. When encountering abnormal conditions, follow the three-step rule of "observe symptoms - analyze causes - step-by-step treatment," ensuring the bell flowers bloom continuously.
