The Cultivation Method of Phalaenopsis Orchid
Known as the "Queen of Orchids," Phalaenopsis orchids, with their elegant flower posture, have become a favorite of many plant enthusiasts. However, many people often encounter issues such as yellowing leaves and short blooming periods during the maintenance process. In fact, by mastering a few key elements, one can keep Phalaenopsis orchids vibrant all year round.
Mastering the Five Key Growth Elements
The Golden Ratio of Light and Temperature
Phalaenopsis orchids are not completely shade-loving plants and require 2-3 hours of scattered light each day. In spring and autumn, the plants can be placed on an east-facing windowsill, and moved to a south-facing position in winter. For temperature management, follow the principle of "warm days and cool nights," with a day-night temperature difference of 25℃/18℃ to promote bud differentiation.
Special Treatment of Sphagnum Moss Substrate
It is recommended to use a combination of sphagnum moss and pine bark as the substrate, and retain 1/3 of the old growing medium each year to help maintain the balance of microorganisms. New sphagnum moss should be soaked in water for 6 hours and then squeezed dry before use, with the diameter of pine bark particles controlled between 0.5-1 centimeter.
Smart Watering Schedule
Adopt the "three-look watering method": first, look at the surface of the substrate turning white; second, feel the sphagnum moss dry; third, lift the pot to feel light. In winter, water in the morning at 10 o'clock on sunny days, and in summer, change to the evening, with the water temperature not exceeding 3℃ difference from the ambient temperature.
Avoiding Three Maintenance Mistakes
Timing of Repotting
The best time for repotting is during the stage when new roots are emerging (late spring to early summer), retain healthy aerial roots, cut off the blackened and rotten roots, let them dry for 2 hours before potting. Avoid repotting during the blooming period or in low-temperature seasons.
Key Points for Nutritional Supplements
Use a balanced fertilizer (20-20-20) during the growing period, and switch to a high-phosphorus and potassium fertilizer during the budding period. Follow the principle of "frequent application of thin fertilizer," dilute the concentration to 1/3 of the standard dosage, and complement with a foliar fertilizer once a month to supply trace elements.
Humidity Management Techniques
Maintain humidity through the "pot-in-pot method": place a decorative pot outside the cultivation pot and fill the space in between with moist ceramic stones. Keep good ventilation during morning and evening misting to prevent water accumulation in the leaf core, which can cause rot.
By precisely controlling the light cycle, scientifically proportioning the growing medium, and establishing a regular maintenance rhythm, Phalaenopsis orchids can bloom all year round in a home environment. Regularly observe the plant's condition, and when new leaves become thicker and aerial roots are plump, it indicates that the maintenance method is appropriate. Remember "30% care and 70% observation," and avoid excessive intervention to allow the orchid to naturally display its elegant posture.
