Is Huilan Suitable for Keeping in the Living Room?
Placing Huilan in the living room can enhance the home's elegance and purify the air. However, to ensure the healthy growth of this graceful orchid plant, it is necessary to master scientific environmental control methods. This article systematically sorts out the key elements of home care, from light intensity, pot selection to temperature control.
Light Intensity Management Standards
The east-facing window is the best habitat for Huilan, requiring more than 4 hours of scattered light exposure daily. From 10:00 to 15:00 in summer, a shade rate of 40% gauze curtain should be used to filter direct sunlight, while in winter, it can be exposed to full sunlight. If there is insufficient light, it is recommended to supplement with LED plant grow lights, keeping the light distance at 50cm to avoid burns.
Deep Pot Planting Technical Standards
Choose a purple sand or ceramic pot with a height of over 30cm, and lay a 3cm thick layer of volcanic rock particles at the bottom of the pot. The matrix should be prepared according to the ratio of pine bark: vermiculite: charcoal = 5:3:2, and the soil should be replaced every spring for two years. The water level in the water tray should be lower than the breathable holes at the bottom of the pot to avoid root immersion.
Air Circulation System
The air flow is best within 1.5 meters from the window. It is recommended to open the window for ventilation twice a day, each time for more than 30 minutes. When using a circulating fan, set it to low speed and avoid the wind direction blowing directly on the plant. During the plum rain season, a dehumidifier should be turned on to maintain a humidity of 60%-70%.
Key Measures for Flowering Regulation
Low-temperature vernalization is required from March to April every year, moving the plant to a closed balcony with a temperature of 5-10°C at night. Phosphorus and potassium fertilizers should be applied from mid-April, and a 0.1% phosphorus acid hydrogen potassium solution should be sprayed weekly. Maintaining a day-night temperature difference of more than 8°C after budding can effectively extend the flowering period to 25 days.
By precisely controlling the light cycle and temperature changes, combined with a scientific matrix mixing ratio, it is also possible to achieve regular flowering of Huilan in the living room. Regularly observe the luster of the leaves and the fullness of the pseudobulbs, and adjust the care plan in a timely manner, making this elegant orchid plant a permanent green decoration in the living room.
