Method of Cultivating Brugmansia in Winter
With the sudden drop in temperature, tropical flowers like Brugmansia face a survival test. As a typical bulbous plant, its winter care directly affects the quality of flowering in the following year. This article will systematically analyze two overwintering methods, helping you choose the best maintenance strategy according to your actual situation.
One, Overwintering Preservation Methods of Brugmansia
1.1 Bulb Dormancy Preservation Method
When the environmental temperature continues to be below 5℃, it is recommended to adopt bulb preservation: ① Choose a sunny morning to operate, loosen the soil along the pot wall with a gardening shovel ② Cut off the stems more than 3cm away from the bulb, retain the nutrients at the base ③ Keep the bulbs in a dry place for 7-10 days, make sure to turn the bulbs every day ④ Wrap with a microporous preservation bag, place a desiccant inside and refrigerate (3-5℃)
1.2 Three Elements of Environmental Control
Special attention should be paid during storage: • Humidity monitoring: check monthly if the bulbs are dehydrated and shrinkage • Disease prevention: can sprinkle carbendazim powder to prevent mildew • Ventilation management: open and close the storage cabinet twice a week for ventilation
Two, Continuous Maintenance Management Plan
2.1 Creating Indoor Overwintering Environment
Maintaining a room temperature of 10-15℃ can continue growth: • Light configuration: 4 hours of direct sunlight on the south-facing windowsill every day • Temperature and humidity linkage: use a humidifier to maintain 40% air humidity • Air circulation: open the window for ventilation for 1 hour every day (avoiding cold spells)
2.2 Accurate Water and Fertilizer Control
Winter maintenance needs to adjust the maintenance rhythm: ① Extend the watering cycle to 15-20 days/time ② Use warm water at 25℃ to water slowly along the pot edge ③ Stop applying nitrogen fertilizer from December to February of the following year, and supplement with phosphorus and potassium fertilizer (diluted to 1/2 concentration) every month
Three, Key Operation Precautions
• Check the integrity of the bulbs: retain 1/3 of the original soil when digging • Temperature difference buffer treatment: gradually reduce the duration of sunlight for 3 days before entering the room • Management during the复苏 period: the plants need to go through a 7-day acclimatization process when moved out in spring
Through scientific overwintering management, Brugmansia can not only safely survive the cold winter, but also accumulate energy to bloom more beautiful flowers in the coming year. Whether choosing bulb preservation or continuous maintenance, mastering the temperature critical point and environmental regulation skills can make this beautiful flower decorate our living space year after year.
