As we enter September and October, the temperature in the southern regions is most suitable for growing Phalaenopsis (Moth Orchids), especially for beginners. This is the best time to bring a Phalaenopsis home, as the plant is most likely to adapt to its new environment. With proper care, it will bloom successfully in the future.
Generally speaking, when you bring the Phalaenopsis home, as long as the environmental temperature is between 15 to 28°C, simply leave the plant in its original pot for 1 to 2 weeks to help it acclimate. However, one important thing to check before bringing the plant home is the condition of its roots. Make sure the roots aren’t blackened or rotting. If you find any, you must trim the damaged roots and apply a fungicide (such as Carbendazim) to prevent infection.
In terms of light and location, it’s best to place the plant in an area with bright, indirect light, such as a north-facing windowsill, or about one meter away from east or south-facing windows. Make sure the orchid is not exposed to direct sunlight (especially when it’s just arrived, as its roots are very sensitive). During the acclimation period, avoid frequently moving the plant, as the changing environment—varying in temperature and light—will make it harder for the plant to adjust.
For watering, it’s best to touch the substrate before watering. If the moss or bark is still moist, don’t water yet. If it’s dry, you can use the soaking method: simply place the pot in shallow water for 10 minutes, then remove it and let the excess water drain (place it in a well-ventilated area). If the substrate is extremely dry, don’t water too much all at once. Use a method of watering little by little over multiple times. Water it slightly one day, and then add a bit more after a couple of days to gradually restore moisture. Otherwise, overwatering too quickly could lead to root rot. Also, when watering, make sure no water accumulates in the center of the leaves, as this can cause crown rot. If water accidentally gets in, use a paper towel to absorb it.
Finally, for temperature and humidity, the most suitable temperature for acclimating the Phalaenopsis is between 18 to 28°C. Temperatures lower than 15°C or higher than 30°C can make the plant more susceptible to diseases. The ideal humidity is between 50% and 70%. If the air in your office or home is too dry, you can place a dish of water near the pot or use a humidifier. However, avoid spraying water directly on the leaves, as Phalaenopsis is particularly sensitive to water on its leaves during the acclimation period.
