What should I do if Lulu is about to freeze to death
Low temperatures in winter often cause green radish to encounter survival crisis. When the leaves are found to be yellow and wilted and the stems are soft, it means that the plants have developed symptoms of frostbite. This article will systematically analyze the scientific treatment plan for green radish after frostbite, from first aid treatment to preventive measures, and help your green plants regain vitality. Green radish Frostbite First Aid Trilogy Precision pruning of withered tissue and found that the first pruning should be completed within 24 hours after frostbite: Use alcohol-disinfected scissors to remove completely withered leaves and branches at a 45° angle, retaining 1-2 healthy buds at the base. point. Focus on observing whether transparency or black rot appears at the stem nodes. Such damaged parts need to be completely removed. Spray the incision with carbendazim solution immediately after pruning to prevent bacterial infection. The intelligent temperature-controlled maintenance method transfers the plants to a bright scattered light environment of 15-18 ° C to avoid direct contact with the radiator. A three-layer temperature control method can be used: the outer layer is covered in a transparent plastic bag (breathable for 2 hours a day), the middle layer is wrapped in cotton cloth, and the bottom is padded with foam insulation board. Use a thermohygrometer to monitor, maintain 60% air humidity, and replenish water on the leaves twice a day through a sprayer. Advanced cuttage regeneration is aimed at severely frostbitten plants. Select stem sections with 2-3 aerial roots, soak them in indolebutyric acid rooting solution for 30 minutes, and insert them into a mixed substrate of perlite: vermiculite =3:1. Keep the medium moist state, use a transparent storage box to make a simple greenhouse, and ventilate it once a day in the morning and evening. New buds can be seen to germinate after about 15 days, and the light intensity can be gradually increased at this time. Frostbite prevention and daily maintenance In winter, green radish should be placed more than 1.5 meters away from the window, and double curtains should be used to adjust the night temperature. Apply seaweed fertilizer once a month to enhance cold resistance, and rotate the pot 15° every week to maintain uniform light exposure. When the room temperature is lower than 10℃, LED plant fill light can be used to fill light for 4 hours a day to maintain metabolism.
Through the triple measures of timely pruning, scientific temperature control and regenerative cuttage, combined with daily temperature monitoring and nutritional management, even severely frostbitten green radish can regain its vitality. Remember that winter maintenance must follow the "three control principles": water control (watering once every half month), temperature control (15-25℃), and fertilizer control (stopping nitrogen fertilizer) can ensure that green radish can survive through the winter safely.
