How to Care for Phalaenopsis Orchids in Winter
Let's talk about how to care for phalaenopsis orchids in winter and some knowledge about the green plant flowers, such as the techniques for maintaining phalaenopsis orchids in winter. Let's learn about it together.
In winter, phalaenopsis orchids should be placed in a location with ample scattered light to ensure a warm and comfortable environment, with a temperature controlled around 25°C. Below 15°C, they are prone to frostbite. Watering should keep the planting medium moist, and the succulent roots of phalaenopsis orchids should not accumulate water. Water when the soil is completely dry, about once every 3-7 days. If possible, increase the humidity of the environment to enhance the beauty of the flowers. During the bud stage, apply phalaenopsis-specific fertilizer once every two weeks, and stop fertilizing during the blooming period. Make sure to ventilate regularly and spray pesticides to prevent diseases and pests. Remove withered flowers and yellow leaves in time to avoid nutrient consumption.
The petals of phalaenopsis orchids resemble fluttering butterflies, with numerous flowers and a long blooming period. Let's talk about the methods and precautions for caring for phalaenopsis orchids in winter.
Provide a Warm and Humid Environment in Winter
Phalaenopsis orchids are not cold-resistant. In winter, they require a warm and humid environment, with a temperature maintained at around 25°C. The nighttime temperature should not drop below 15°C, or the plant may be frostbitten. If the indoor temperature is too high, above 35°C, the plant may easily develop diseases and pests.
Placing It in a Bright, Scattered Light Position Indoors in Winter Helps Phalaenopsis Orchids Bloom
Phalaenopsis orchids enjoy soft scattered light. In winter, the light is not strong, so it's safe to expose them to sunlight, and 8 hours of sunlight per day is fine. However, in regions with strong sunlight in the south, it is still recommended to keep them on an east-facing windowsill to prevent sunburn.
Adjust Watering Frequency Based on Temperature
Phalaenopsis orchids prefer a warm and humid environment, with aerial roots that like moist and well-ventilated soil and are most afraid of waterlogging and root rot. Therefore, when caring for phalaenopsis orchids in winter, it is essential to ensure the breathability of the planting medium. When the environmental temperature is around 15°C, water once a week. At around 20°C, water every 3 days. Each watering should only moisten the soil and there's no need to water until it's completely dry. When watering, be careful not to pour water on the crown or flowers to prevent rot.

Air Humidity, Bright Petals
Phalaenopsis orchids prefer about 60% humidity. In winter in the north, because indoor heating is usually on, although the temperature is guaranteed, the environment can be quite dry. It is recommended to mist the surrounding environment of the potted plant frequently or place a humidifier near the phalaenopsis orchid to increase humidity.
Stop Fertilizing After Blooming, or Flower Buds May Drop Prematurely
In winter, when phalaenopsis orchids are in the bud formation stage, it is important to supplement fertilizer timely and adequately, applying thin and frequent fertilization. In an environment with a suitable temperature, apply phalaenopsis-specific fertilizer once every two weeks to promote bud growth. If the temperature is low, stop fertilizing, or the roots will not absorb the nutrients, leading to burning. After the phalaenopsis orchid blooms, stop fertilizing, or the flower buds may fall, shortening the flowering period for observation.
Ensure Proper Ventilation, but Avoid Cold Wind Damaging the Flowers
In winter, to keep the indoors warm, doors and windows are usually closed. However, to care for phalaenopsis orchids and prevent the spread of diseases and pests, it is still necessary to open the windows for ventilation regularly. Additionally, spray insecticides and fungicides monthly for prevention.
