How to Manage Campsis in Winter
As a common climbing plant in traditional Chinese gardens, Campsis is deeply loved by horticulture enthusiasts for its brilliant orange-red flowers. In the cold winter, how to maintain this bright color? This article will systematically analyze the key points of winter care and scientifically interpret the phenomenon of defoliation.
Three Core Management Strategies for Campsis in Winter
Strategies for Nutrient and Water Regulation
After the beginning of winter, fertilization should be stopped immediately, as the roots' activity weakens after the plant enters hibernation, and continuous fertilization can easily lead to fertilizer damage. It is recommended to apply phosphorus and potassium fertilizers in the late autumn to enhance cold resistance and store energy for overwintering. Watering intervals should be extended to 10-15 days per time, using the method of slow watering along the pot edge at noon, keeping the soil slightly moist.
Double Protection of Light and Temperature
At least 4 hours of direct sunlight is required daily, with the ideal overwintering position being a south-facing balcony or courtyard. In the northern regions, when the temperature drops below 5°C, it is recommended to build a double-layer plastic greenhouse, with the inner layer 20cm away from the plant to form a thermal insulation layer. For ground-planted plants, double protection can be used by wrapping the stems with straw and covering the roots with plastic film.
In-depth Analysis of Winter Defoliation Phenomenon
Defoliation Mechanism and Countermeasures
As a typical deciduous vine, when the environmental temperature is continuously below 8°C, Campsis will initiate a self-protection mechanism, reducing water evaporation and nutrient consumption by shedding leaves. This process is a normal physiological phenomenon, and it is important not to force the retention of leaves. After defoliation, the fallen leaves on the ground should be cleared in a timely manner to prevent the breeding of diseases and pests.
Special Climate Countermeasures
In southern regions where the average winter temperature is above 0°C, semi-defoliation may occur. At this time, basic care should be maintained without excessive intervention. If temperatures below -5°C are encountered, the plant should be wrapped with non-woven fabric, combined with bamboo stakes for support to prevent branches from being bent by freezing rain.
Through scientific winter management, Campsis can not only survive the winter safely but also store energy for flowering in the coming year. By mastering its defoliation patterns and adjusting the care strategy reasonably, this climbing plant can surely shine again in the spring.
