What should I do if I lose a lot of leaves in winter?
When the chilly wind sweeps through the courtyard and the bluegrass leaves its beautiful clothes and leaves only its branches, many flower friends often fall into anxiety. As a climbing plant widely planted in the north and south of my country, the winter maintenance of creepers does require special attention. This article will systematically analyze the nature of falling leaves and provide operable guidelines for wintering. The biological interpretation of winter leaf shedding of climbers is a natural physiological phenomenon of the genus Deciduous. Campsis grandiflora is a typical deciduous woody vine with a high anthocyanin content in its leaves. When the temperature continues to fall below 10 ° C, the plant initiates a self-protection mechanism to reduce water evaporation and nutrient consumption through falling leaves. This phenomenon is the same as the autumn red leaves of maple trees. If abnormal leaf fall identification characteristics are accompanied by branch wilting, leaf disease spots, or early leaf fall (earlier than November), the root system needs to be checked for water and rot. You can observe the cross-section of the branch: healthy branches are bluish-white, and sick branches are brown. The golden rule of water control in the triple overwintering maintenance system of bluegrass in winter watering needs to follow the "three-look principle": look at the temperature (cut off water below 5℃), look at the medium (dry soil and then replenish water), and look at the weather (operate at noon on sunny days). In the northern region, it is recommended to use film covering on the roots to protect moisture, while in the south, attention should be paid to shelter from rain and prevent waterlogging. Collaborative management of light and heat displaces the plants to the south facing the sun, and guides the branches through bamboo pole brackets to form a three-dimensional lighting surface. In the severe cold areas of the north, the trunk can be wrapped with non-woven fabrics and the roots can be covered with plastic film to form a three-dimensional cold-proof system of "protecting the top and protecting the bottom." Nutritional management strategy completely stops fertilization from November to February of the following year, but phosphorus and potassium fertilizers can be applied before the beginning of winter to enhance stress resistance. Special reminder: Undecomposed organic fertilizers are prohibited in winter, which may cause root burns. The best time for pruning time and space art in winter is from December to January in the Yangtze River Basin, and it needs to be advanced to late November in the north. Master the "Sanjiu pruning method", that is, operate when the average daily temperature is higher than 0℃ for three consecutive days to avoid frostbite on the incision. The scientific pruning technique adopts the "three-level pruning method": 3-5 bud points are reserved for the first level branches, the second level branches are thinly cut and crossed branches, and the third level branches are completely cleared of pests and diseases. Apply healing cream in time after pruning to prevent bacterial infection.
Following these maintenance tips, when spring returns to the earth, the mountain sky flower will surely bloom into a flame-like orange-red flower waterfall in a more vigorous manner. The four seasons of plants are teaching us the wisdom of conservation in accordance with the laws of nature.
