How often to water orchids
As a representative of elegant flowers, orchids are extremely sensitive to water management. Mastering scientific watering methods is the core technology of orchid care, which needs to be adjusted flexibly according to seasonal changes, environmental changes, and plant characteristics. This article verifies through practice the watering rules to help growers accurately control the water supply for orchids.
Core elements of orchid watering cycle
Seasonal difference control method
In spring and autumn, water every 2-3 days, in summer, water twice a day, early morning and evening, and in winter, extend to 5-7 days. Special weather needs to be combined with temperature fluctuations: reduce water supply during continuous rainy days and increase atomized spraying during dry and hot weather.
Environmental variable calculation method
Ventilation conditions, light intensity, and air humidity form a golden triangle: increase watering by 20% in strong light environments, open windows for ventilation for 1 hour after watering in enclosed spaces, and increase humidity with a tray when humidity is below 40%.
Advanced orchid watering techniques
Golden timing selection
In summer, prioritize watering between 5-7 AM to avoid scalding the roots during the hot noon. In winter, choose the warm period between 10 AM and 2 PM, and adjust the water temperature to the range of 18-22°C.
Quantitative渗透 standard
Use a progressive watering method: after the first watering, rewater after a 2-minute interval until water flows out of the pot bottom for 10 seconds. For terra cotta pots, increase water by 30%, and for purple sand pots, reduce watering by 20%.
Risk prevention and control of orchid watering
Matrix status monitoring
Insert a bamboo stake into the deep matrix and observe the color change after 15 minutes. If only the top 2 cm is moist, water immediately, and if the middle and lower layers are damp, delay watering.
Disease prevention measures
Add fungicides (multi-fungicide 1500 times solution) every 3 times of watering, and use bamboo charcoal particles for mulching before and after the rainy season to effectively prevent root rot caused by waterlogging.
Scientific watering is the lifeline for the healthy growth of orchids. It is recommended that growers establish a watering log, record temperature, humidity, and plant responses, and gradually master personalized water supply plans through a 3-month observation period. Combined with regular potting and matrix improvement, the orchid roots can always maintain the best moisture content.
