What is the minimum cold tolerance temperature for Phalaenopsis orchids?
Today, we will introduce the content about the minimum cold tolerance temperature for Phalaenopsis orchids in the aspect of green plants and flowers. Next, the editor will provide you with detailed answers.
What is the minimum cold tolerance temperature for Phalaenopsis orchids?
Phalaenopsis orchids are not cold-tolerant, with a cold tolerance temperature of 5 degrees. They can withstand temperatures as low as 5 degrees. When temperatures drop below 5 degrees, Phalaenopsis orchids may suffer frostbite. In winter, if temperatures drop to 10 degrees, the orchids will enter a temporary dormant state. It is best to move the plants indoors for care in cold winter, maintaining a stable temperature of around 16 degrees Celsius, so that the plants can safely survive the severe cold of winter.
Phalaenopsis orchids bloom in winter when other flowers are fading, but many people find an embarrassing situation when caring for them: they do not bloom during the flowering period! This is due to poor care during winter.
Are Phalaenopsis orchids cold-tolerant?
Phalaenopsis orchids are not cold-tolerant. As a type of orchid growing in tropical regions, the suitable temperature for Phalaenopsis orchids should be between 16-30 degrees. Moreover, during the growth process, it is necessary to maintain the temperature above 15 degrees for the orchids to grow more vigorously and the flowers to be more vibrant.
What is the lowest temperature Phalaenopsis orchids can tolerate?
The cold tolerance temperature for Phalaenopsis orchids is 5 degrees. They can withstand temperatures as low as 5 degrees. When temperatures drop below 5 degrees, the orchids may suffer frostbite. In winter, if temperatures drop to 10 degrees, the orchids will enter a temporary dormant state.
Therefore, it is necessary to move the plants indoors as soon as winter arrives. If the Phalaenopsis orchids are frostbitten, do not immediately place them in a warm area. Let them recover first, as a sudden change to warmth can easily lead to the death of the orchids.
Tips for overwintering Phalaenopsis orchids
1. Control temperature
When overwintering Phalaenopsis orchids, the first thing to pay attention to is temperature control. These plants thrive in warmer environments, so it is best to move them indoors in cold winter, maintaining a stable temperature of around 16 degrees Celsius to help them safely survive the severe cold.
2. Manage watering
When watering Phalaenopsis orchids, make sure that the temperature of the water is not too different from the temperature of the soil. Since water evaporation is slow in winter, water the soil just enough to make it slightly dry or slightly moist.
3. Manage fertilization
Phalaenopsis orchids are fertilizer-loving plants. Even when the winter temperature is not very low, it is still necessary to supplement fertilizers. Considering this is the period of flower bud differentiation for the plants, it is important to apply more phosphorus fertilizers. However, follow the principle of applying thin fertilizers frequently, using dilute phosphorus fertilizers every 15-20 days.
4. Strengthen ventilation
In winter, caring for Phalaenopsis orchids indoors can avoid many problems that occur outdoors, such as exposure to wind and rain and damage from snow. However, it is essential to open windows regularly for ventilation to allow indoor and outdoor air to circulate. But be careful not to expose the plants directly to cold winds, as this may cause them to shed leaves.
