Should orchids be watered after repotting? Techniques for watering orchids after repotting.

Do the orchids that have just been replaced need watering?

Changing orchids is an important part of the maintenance process, but many flower lovers have doubts about the watering operation after changing the pots. The correct watering method directly affects the effect of plants serving pots. This article will systematically analyze the watering strategies under different pot changing scenarios to help you master scientific conservation skills after changing pots. 1. Watering judgment standards after pot change 1.1 Analysis of humidity of plant materials When using dry plant materials to change pots, it is recommended to pour thoroughly root-fixing water to promote root attachment. If wet plant material (moisture content above 40%) is used, watering should be delayed for 3-5 days to avoid stagnant water causing root rot. It can be judged by the bamboo stick test method: Insert the bamboo stick into the planting material for 2 hours and observe it. If there is no moisture on the surface, water needs to be replenished. 1.2 Principles for treatment of root damage: Plants with pruned roots need to rest for 72 hours before watering. The environmental humidity needs to be maintained at 60%-70% during the wound healing period. It is recommended to use bagging to moisturize and ventilate for 2 hours a day to avoid the growth of fungi. 2. Technical points of phased watering 2.1 Root watering techniques Using dipping pot method is more conducive to the uniform water absorption of the plant material: immerse the flower pot at 1/3 of the water surface height, and remove it immediately when the surface of the plant material is moist. The temperature difference between the water temperature and the ambient temperature should be ±2℃ to avoid stimulating the root system. 2.2 Water management during the slow pot period (about 15-30 days), a watering cycle of "seeing dry and seeing wet" needs to be established. Use an electronic hygrometer to monitor, and when the humidity of the plant material at a depth of 10cm is ≤30%, use foliar spray (atomization rate>90%) to replenish water. 2.3 The seasonal difference adjustment plan is to replenish water once a week in spring and autumn, 3-4 days per time in summer (avoid noon), and 10-15 days per time in winter. It is recommended to complete watering at 9-11 o'clock to ensure full evaporation during the day. 3. Advanced maintenance supporting measures are combined with watering for nutritional supplements: add rooting agent (diluted 2000 times) for the first watering, and use EM bacterial solution (1:500) for the second time. Maintain the temperature difference between day and night of 8-10℃, and control the light intensity at 10,000 - 15,000 Lux.

By accurately controlling the amount and timing of watering, and coordinating with environmental control, the root system of orchids can be rebuilt within 20 days. Keep in mind the basic principle of "growing roots dry and growing leaves wet" and make dynamic adjustments based on the ratio of plant materials (recommended pine bark: planting gold stone =7:3) to cultivate strong orchid plants.
