Can minus 6 degrees water the wealth tree?
In the cold winter, the maintenance of fortune trees has become the focus of attention of many plant lovers. As a typical tropical leaf-viewing plant, Fortune Tree is extremely sensitive to low temperatures, and watering in winter is the key to its life and death. This article will deeply analyze the watering taboos in low-temperature environments and systematically introduce the three core maintenance points. 1. The fatal impact of sub-zero low temperature on the Fortune Tree 1.1 The formation mechanism of freezing injury When the environmental temperature drops below 5 ° C, the cell fluid of the Fortune Tree begins to crystallize, and the absorption function of the root system is completely suspended. Extreme low temperatures of minus 6 degrees can cause cell walls to rupture, manifested in irreversible damage such as black spots on leaves and soft rot on stems. 1.2 Watering aggravates freezing damage. At this time, watering will form soil ice crystals and directly tear capillary roots. Experimental data shows that the survival rate of Fortune trees after watering in a sub-zero environment is less than 10%, while the survival rate of unwatered plants can reach 35%. 2. Three elements of scientific watering in winter 2.1 Frequency control is recommended to adopt the "three observation method": observe that the depth of cracking of the basin soil reaches 3cm, observe that the leaves are slightly wilted, and observe that the environmental humidity is less than 40%, before watering. Heating rooms in the north can be used for 20 days per time, and extended to 40 days per time in wet and cold areas in the south. 2.2 Water temperature adjustment Leave tap water to stand for 48 hours and equilibrate with room temperature after chlorine evaporates. Professional tests show that water temperature of 25 ° C can increase root absorption efficiency by 60%. A water temperature meter can be used to monitor to ensure that the temperature difference does not exceed ±3℃. 2.3 The best watering time is 10:00-14:00 on sunny days, when the rising ground temperature can accelerate water absorption. Avoid watering in the evening and causing stagnant water and freezing at night. 3. Special case handling plan 3.1 Immediately cut off the water when frozen plants are rescued and frostbite occurs, use a brush to remove decaying tissue, and apply charcoal powder to the wound. Gradually raise the temperature to 15℃, and restore a small amount of water supply after the new buds germinate. 3.2 Floor heating environment maintenance The bottom of the basin is covered with a 3cm perlite insulation layer, and atomized spray leaves are used instead of watering the roots. The air humidity is maintained at 55%-65%.
Through scientific water control combined with temperature management, even in the severe cold areas of the north, fortune trees can safely survive the winter. Remember: Winter maintenance is better dry than wet, and be patient and wait for the recovery of spring.
