Can茉莉 outdoor survive the winter
As winter approaches, can the pure and fragrant jasmine safely survive outdoors? This question concerns countless flower lovers. As a typical tropical and subtropical plant, jasmine requires scientific planning and careful care to survive the winter. We will analyze the key elements of winter care from three dimensions: climate differences, maintenance techniques, and emergency protection.
Regional climate determines the wintering plan
Advantages of maintenance in warm southern regions
In areas south of 25 degrees north latitude, the average daily temperature in winter is mostly maintained above 5℃, and plants can be placed in a sunny and windward position outdoors for wintering. Moderate low temperature stimulation can enhance the lignification of branches and improve the quality of flowering next year. However, it is still necessary to take temporary warming measures when cold currents occur.
Key points of protection in cold northern regions
When the temperature continues to be below -3℃, the plant will suffer irreversible frost damage. It is recommended to move into the room in the last ten days of October in the north of the Yellow River, with a south-facing enclosed balcony of 5-10℃ being the best choice. Maintain environmental ventilation and avoid direct blowing of heating to prevent leaf dehydration.
Exquisite management ensures safe wintering
Key period for water control
During the dormant period, water control must be strict, adding a small amount of water only after the potting soil is completely dry. It is recommended to use softened water that has been left at room temperature for 3 days, with watering time chosen around noon to avoid low temperature stimulation to the roots. The monthly water supplement is about 1/3 of the growing period.
Physical protective measures
Outdoor wintering plants are recommended to adopt multiple layers of protection: first wrap with a non-woven fabric thermal insulation cover, and then cover with a perforated plastic bag to prevent rain and snow. Choose sunny weather every week to uncover the outer layer for 2-3 hours to maintain the circulation of the microenvironmental air.
Strategies for dealing with special climates
Special attention is needed during the late spring cold period. When there is a sharp drop in temperature, a 10cm thick layer of decomposed leaf soil can be piled at the base of the plant for insulation. For potted plants, it is recommended to set up a caster tray for quick transfer to a wind shelter. Combined with spraying seaweed foliar fertilizer, it can enhance the frost resistance of cells.
By scientifically judging the characteristics of regional climate and cooperating with stage-based maintenance strategies, jasmine can safely survive the winter in different climatic zones. The key lies in observing the plant's condition, adjusting the protection intensity in a timely manner, and allowing this fragrance in winter to continue.
