How do cockscomb flowers survive the winter
As a gorgeous representative of annual herbs, cockscomb flower has become a frequent visitor to courtyard landscaping with its unique crown. But in the face of the severe cold test of winter, can this bright red survive the winter safely? Mastering scientific conservation methods is particularly important. Four core strategies for winter protection: Cold prevention and warmth prevention measures. When the temperature drops to 5 ° C, the cold prevention process needs to be started. Use a thick plastic film with a light transmittance of 80% to make the windproof cover. It is recommended to choose bagging after dew evaporates in the morning. When bagging, pay attention to reserve a 5-8cm breather seam to avoid excessive humidity caused by complete sealing. In the northern region, non-woven fabrics can be stacked for double protection. Precise moisture control Winter watering requires following the "three observation principles": observe the soil dryness (3cm dry on the surface layer), observe the leaf condition (slight wilting), and observe weather changes (continuous sunny days). Use warm water at about 25℃ and slowly pour along the edge of the pot, and control the single watering amount to 1/3 of that in summer. Special reminder: In rainy and snowy weather, the water in the basin must be poured in time. The light management system should ensure direct light for 4-6 hours a day in winter. It is recommended to adopt the "stepped fill light method": when natural light is insufficient, use a full-spectrum plant fill light to fill light during two periods: 9:00-11:00 and 14:00-16:00. Pay attention to rotating the flowerpot regularly to ensure that the plants receive uniform light and avoid misaligned crowns. Regulation of nutrient supply Apply potassium dihydrogen phosphate (diluted 1500 times) 7-10 days before the beginning of winter for cold-resistant exercise. Nitrogen fertilizer is strictly stopped during the winter. If yellow leaves appear, 0.2% ferrous sulfate solution can be sprayed on the leaves every month. Special note: Indoor overwintering plants should pay attention to stay away from radiators, and maintaining a dormant temperature of 5-8℃ is more conducive to rejuvenation in the coming year.
Through the above four-dimensional maintenance system and regular inspections (opening the protective cover once a week for ventilation), even in extreme weather of-5℃, the survival rate of cockscomb can reach more than 85%. Gardening practice shows that plants that survive scientifically can increase the number of flowering plants by 30% and the color saturation by 20% the next year. Remember: Patient observation and moderate intervention are the key to safe overwintering of plants.
