Phalaenopsis orchids are extremely beautiful flowers that many families choose to keep indoors for their elegance. When the flowers bloom in winter, they add a festive and vibrant atmosphere. However, Phalaenopsis orchids are quite demanding in terms of their growing environment, especially in the selection of planting materials and the control of temperature and humidity. It is not easy to cultivate them well. Below are some detailed issues to consider when caring for Phalaenopsis orchids.
1. Choosing Planting Materials
Phalaenopsis orchids often grow on decaying trees in the wild and prefer a warm, humid environment. When growing them at home, it's important to provide a suitable environment. For planting materials, it's best to use more loose and breathable substances like moss, bark, tree fern roots, broken tiles, and coconut shells. These materials have good water retention and breathability, which can promote vigorous growth and more beautiful blooming.
When preparing the soil, you can use perlite, coconut bran, and tree fern roots to create a cultivation mix. This helps the leaves grow rapidly, increases the rate of flower bud differentiation, speeds up the development of flower stalks, and leads to earlier blooming.
2. Proper Watering
Phalaenopsis orchids like moisture, and their roots have a strong absorption capacity, taking in oxygen, nutrients, and water. However, it's important to manage watering properly. Excessive water can affect root respiration and lead to suffocation and root rot over time. When watering Phalaenopsis orchids, use a fine stream of water and avoid getting the leaves wet to prevent rot. Also, the quality of water is crucial; if using tap water, let it sit for a few days before watering.
3. Supplementing Nutrients
To ensure that Phalaenopsis orchids bloom on schedule, it's necessary to ensure adequate nutrition. During the growing period, to promote growth, you can apply a compound fertilizer solution every two weeks, with each application being light and frequent. Fertilizing should be paused when the temperature is above 32°C or below 15°C.
After entering October, supplement phosphorus and potassium fertilizers. You can use a 0.1% solution of potassium dihydrogen phosphate for root exterior application or foliar spray, and start controlling watering to promote the formation of flower buds.

4. Light Requirements
Phalaenopsis orchids prefer a warm, humid, and semi-shaded environment, avoiding direct sunlight. In the summer, when the intensity of sunlight is high, it's essential to provide shade. In spring and autumn, you can place the potted plants in a place with diffused light to facilitate photosynthesis and promote plant growth. In winter, when light intensity decreases, ensure adequate light by placing the plant in a location with weak light, which is more conducive to bud formation and flowering.
5. Temperature Requirements
Phalaenopsis orchids are winter-blooming flowers that require a higher temperature to bloom normally. Their optimal growing temperature is around 15°C to 20°C. The minimum winter temperature should not be below 5°C, or the plant may freeze. Therefore, during the budding and flowering period, it's important to provide a suitable growing temperature.
In addition to the above aspects of care, it's also important to maintain the humidity of the surrounding environment. If part of the plant shows signs of drought and the leaves are drooping, promptly spray water around the pot to increase the humidity, which is beneficial for blooming.
