Complete Guide to Preventing White Orchid Root Rot
1. Scientific Water Control Maintenance Method
Fleshy root water storage characteristic: White orchid fleshy roots contain 80% water, and water accumulation for 24 hours can cause cell necrosis. It is recommended to use the "finger test method" - water when there is no moisture when the index finger is inserted into the potting soil 2cm deep.
Seasonal watering amount comparison: • Spring and autumn: 5-7 days/time (keeping the soil slightly moist) • Summer: 1 time each morning and evening (avoiding high-noon heat) • Winter: 15-20 days/time (adjusted with environmental humidity)
2. Precise Fertilization Management Technique
Fertilizer concentration calculation formula: During the growing period, it is recommended to use diluted organic liquid fertilizer at 1500 times, controlling the single dose by (plant height cm ÷ 10) ml. For example, 3ml of fertilizer for a 30cm plant each time.
Remedial measures: If fertilizer damage is found, immediately adopt the "threefold dilution method," washing the potting soil with water for 3 consecutive times, and using ceramic stones at the bottom to enhance drainage.

3. Five-Step Rescue Process
① Pot removal and cleaning: Soak the potting soil for 10 minutes and gently tap the pot wall to remove the roots. ② Root pruning and disinfection: Retain healthy roots with a diameter >2mm and soak in carbendazim solution for 30 minutes. ③ Soil mixture for revival: Decomposed leaf soil +珍珠岩 (perlite) +蛭石 (vermiculite) mixed in a ratio of 5:3:2. ④ Light control and slow seedling: Place in a scattered light area for 15 days of maintenance. ⑤ Root activation: From the third week, water with a rooting powder solution every 10 days.
Maintenance data monitoring: During the recovery period, maintain a day-night temperature difference of 8-10°C and an air humidity of 60%-70%. A 70% rate of new leaf germination indicates a successful rescue.
By adopting systematic preventive measures and standardized rescue processes, combined with precise control of environmental parameters, the incidence of white orchid root rot can be effectively reduced by 80%. It is recommended to conduct root health checks every quarter, use bamboo sticks to regularly measure potting soil moisture, and establish a personalized maintenance log, making you a true expert in white orchid care.
