Can honeysuckle spend the winter outdoors in the north?
As a traditional Chinese medicinal material and ornamental plant, the overwintering ability of honeysuckle has always been the focus of attention of northern flower lovers. This vine, known as "honeysuckle", can still maintain its vitality in the severe cold of minus 30℃ due to its strong cold resistance gene. However, in order for honeysuckle to safely winter outdoors in the north and maintain good growth, scientific maintenance methods still need to be mastered. Feasibility analysis of outdoor overwintering of honeysuckle in the north. Plant cold-resistant genetic advantage Honeymoon is native to northern China, and its lignified stems can effectively withstand low temperatures. Experimental data show that the root survival rate of mature plants can still reach more than 85% in-30℃ environment. However, appropriate protective measures are recommended during the seedling period. Regional climate adaptation characteristics In typical northern climate areas such as Northeast and Northwest, honeysuckle will enter dormant through natural falling leaves. This self-protection mechanism can significantly reduce energy consumption. With correct maintenance measures, the success rate of wintering can reach more than 95%. The moisture control plan for the four-dimensional maintenance system of honeysuckle outdoor wintering will be implemented gradually in late October: ·Soil moisture drops to about 30%. Watering no more than twice a month. Use bamboo stick method to detect moisture, light management strategy in full sunshine in winter.:·Photosynthetic efficiency increased by 40%. Branch lignification accelerated. It is recommended to maintain direct light for more than 8 hours and adjust nutrient supply completely from November to March of the following year: ·Apply phosphorus and potassium fertilizers 2 months in advance·Control the soil EC value below 0.8mS/cm·Cooperate with decomposed pine needles to improve soil plant pruning practices adopt the principle of "three cuts and three stays":·Cut the weak and retain the strong: Remove the thin and weak branches and retain the main branches·Cut the dense and sparse: Maintain a distance of 30cm between branches·Cut the disease and retain health: Thoroughly eliminate pests and diseases. Advanced overwintering protection measures can be taken when extreme cold currents strike: ·Cultivate 20cm soil to the foundation·Wrap non-woven fabric with cold prevention belts·Build temporary wind barriers·Spray antifreeze film preparations Through scientific and systematic maintenance and management, honeysuckle in the northern region can not only safely survive the winter, but also form fuller flower buds in the following year. By mastering these key technical points, this flavor of "honeysuckle" can bloom in a more brilliant manner in the northern land.
