What to Do When the Baby Stars Plants Wither After Transplanting
Seedlings of Baby Stars often exhibit stress responses due to sudden environmental changes after transplanting. Mastering scientific care methods can help the plants quickly recover. This article will systematically explain key operational points from withering first aid to potting care.
First Aid Treatment for Withering Baby Stars After Transplanting
Symptom Diagnosis and Emergency Measures
When signs of withering such as drooping leaves and softened stems are observed, it is necessary to immediately check environmental factors: ① Light intensity exceeding 10,000 lux can cause burns ② Soil moisture below 40% needs to be replenished ③ Air humidity should be maintained at 60-70%. It is recommended to use a 70% shade net and the bottom tray watering method to increase humidity for first aid.
Three Elements of Environmental Control
During the rescue period, maintain a constant temperature of 18-25°C and avoid temperature differences exceeding 8°C. Use a thermometer and hygrometer to monitor in real-time, combined with a timed ventilation system to ensure an air circulation rate of 0.5m³ per hour. Light intensity should be controlled at 5,000-8,000 lux, and it is recommended to use LED plant grow lights for adjustment.
Scientific Watering System After Repotting
Golden Rule of Water Management
Use the immersion pot method to supply water for the first 72 hours after repotting: place the pot in a container with water depth of 3cm and soak for 10 minutes. Then enter the water control period, spray water when the topsoil is dry by 1cm. It is recommended to use a narrow-spout watering can to slowly pour water along the pot wall, with each amount not exceeding 15% of the pot's volume.
Medium Improvement Plan
Blend 30% perlite and 20% vermiculite into the substrate to enhance water retention and breathability. Use slightly acidic water with a pH of 6.0-6.5, and add 0.01% indole butyric acid to promote root development. It is recommended to use a siphon automatic watering system to maintain constant humidity.
Systematic Potting Operation Standards
Best Timing for Potting
Observe the plant's growth cycle: repot when the roots fill the drainage holes and new growth stops. Perform the operation in the early morning when the temperature is stable at around 20°C, avoiding the rainy season or extreme weather. It is suggested to coordinate with the lunar phase, transplanting during the waxing moon phase.
Key Details of Root Treatment
Retain 1/3-1/2 of the original soil ball and make a 45° diagonal cut on the entangled roots. Soak the roots in a 800 times solution of carbendazim for 20 minutes, then dry before planting. Place a 3cm layer of ceramsite at the bottom of the new pot and fill with pre-mixed substrate (garden soil: leaf mold soil: river sand = 4:3:3).
By precisely controlling the four major elements of light, water, temperature, and fertilizer, combined with standardized potting operations, the survival rate of transplanted plants can be increased to over 90%. It is recommended to establish a care log to record daily environmental parameters and plant conditions, gradually improving personalized care plans.
