Is it normal for orchids to appear curled leaves after they are put on the pot
Newly purchased orchids appear curled after transplanting, which often makes growers feel anxious. This special physiological reaction may be a normal manifestation of plants adapting to the new environment, or it may imply that the maintenance process needs to be adjusted. Understanding the causes of leaf curl and the corresponding treatment methods can help the plant smoothly pass through the critical serving period. Analysis of the causes of leaf rolling of orchids in pot physiological phenomena during the root adaptation period. Mild leaf rolling that occurs within 3-7 days after transplanting is mostly normal. At this time, the orchid plant is in the stage of root function reconstruction. The new roots have not yet formed a complete water absorption network, and the absorption efficiency of the old roots is reduced, resulting in temporary water imbalance in the leaves. Maintaining ambient humidity at 60-70% can effectively relieve symptoms. For root-fixing water irrigation at the key node of water management, it is necessary to ensure that the plant material is completely wetted, and the soaking method is used to allow the moss or bark to fully absorb water. Subsequent maintenance keeps the plant material in a "moist but not wet" state, and puts your fingers into the substrate for 2 cm to replenish moisture when it is dried. Pay special attention to avoid stagnant water causing root rot. It is recommended to use a special orchid basin with side holes. Precise control of light intensity requires maintaining a light intensity of 2000-3000lux within 2 weeks after transplanting, which is equivalent to a scattering light environment from the north towards the sill. Use a sunshade mesh to filter 50% of direct light to prevent leaf light suppression reactions. Leaf spray can be carried out for 1 hour in the morning and evening, and air circulation can be maintained with a circulating fan. The orchid transplanting system maintenance plan is coordinated with temperature and humidity to maintain a temperature difference environment of 25-28℃ during the day and 18-20℃ at night. The relative humidity is stabilized at 65%±5% through humidifier or water pan evaporation. Pay attention to avoid superposition of high temperatures and high humidity, and ensure a ventilation period of 3-4 hours every day. Nutrient replenishment time window suspend fertilization for the first 8 weeks after transplanting, and a 3000-fold diluted balance fertilizer can be applied only after crystal heads appear in the new root tips. It is recommended to adopt the principle of "applying thin fertilizer frequently" and supplement foliar fertilizer containing calcium and magnesium every 2 weeks to enhance cell wall toughness.
Through systematic environmental control and precise maintenance, most orchids can complete the serving process in 4-6 weeks. If the rolled leaves are accompanied by blackening or continue to increase at the base, the health of the root system needs to be checked promptly. Only by mastering the growth rhythm of plants and combining moderate intervention with patient waiting can we cultivate strong and elegant orchid plants.
