Five key points to master for orchid care in winter

How to strengthen orchid care in winter is the key to whether the orchids can grow vigorously and bloom in the coming year. To care for and manage orchids well in winter, management measures must be taken according to the variety characteristics of the orchids.

- First, bring them indoors for warmth. When winter arrives, the weather gradually turns cold, and orchids placed outdoors are prone to being hit by cold waves, so they must be moved promptly to a place indoors where sunlight reaches. For those living in apartment buildings, it is best to place the orchid pots on a sunny enclosed balcony. This orientation ensures the orchids receive more sunlight, which is extremely beneficial for their growth, bud formation and flowering. For orchids brought indoors to overwinter, the room temperature should be kept between 5°C and 15°C. If the room temperature is too low, it cannot provide cold protection and warmth; if the room temperature is too high, the flower stems grow slowly and the flower buds develop poorly, which can easily cause already formed flower buds to shrivel and even die. Since Cymbidium goeringii is relatively cold-tolerant and needs a low-temperature period of about 3 weeks to 4 weeks at around 0°C to complete vernalization before it can bloom. Therefore, the most suitable overwintering room temperature for Cymbidium goeringii is between 3°C and 8°C.

Methods for orchid care in winter:

1. You must know exactly what variety of orchid you are growing, and adopt different management methods according to the orchid variety so that the orchids can overwinter safely.

2. Watering

In winter orchid growing, the supply of water is key. As the temperature drops, the nutrient supply for indoor potted orchids is very important. You must water more according to the situation. If the humidity is too low, you can use misting to spray water, which can prevent orchid leaf blight.

3. Fertilizing

In winter orchid growing, fertilizing should be done reasonably, especially before winter begins, apply organic fertilizer to the roots, water once every 10 days, and you can also appropriately spray foliar fertilizer, which can promote better growth of the orchids.

4. Pest and disease control

Winter is a period of high incidence of pests and diseases such as orchid soft rot and stem rot, so pesticides must be sprayed in time for prevention and control, which allows for better orchid growing.
