At what high temperature does Phalaenopsis go dormant? Care during dormancy like this

During the care of Phalaenopsis, understanding its high-temperature dormancy habits and how to respond is crucial, as this ensures healthy plant growth and a smooth passage through this special period.

The growth habits of Phalaenopsis are closely related to temperature; when the ambient temperature climbs to a certain level, it enters a dormant state. Usually, when the temperature remains steady at 32°C or above, Phalaenopsis may gradually stop growing and enter dormancy. However, this is not an absolute figure; different varieties of Phalaenopsis differ slightly in their tolerance to high temperatures. Some more resistant varieties may only go dormant at 33°C - 34°C, while some relatively delicate varieties may show signs of dormancy at around 31°C.

How to care for Phalaenopsis during high-temperature dormancy:

Light regulation: During dormancy, Phalaenopsis's demand for light drops sharply. At this time, avoid strong direct light; move the plant to a spot indoors with soft, bright, indirect light, such as a position 1 - 250% - 70%10 - 152 - 3

Stop fertilizing: During dormancy, Phalaenopsis's physiological activity is weak and its ability to absorb nutrients is very poor. Fertilizing at this time not only cannot be effectively absorbed by the plant but may also cause fertilizer burn and damage the roots. Therefore, once Phalaenopsis is confirmed to have entered dormancy, stop fertilizing immediately, including all kinds of organic fertilizers, chemical fertilizers, and foliar fertilizers, until dormancy ends and growth resumes.

Increase ventilation: In a high-temperature environment, good ventilation is crucial. Ventilation can effectively lower the local temperature and reduce the breeding of pests and diseases. When growing indoors, open windows frequently to ensure air circulation; if growing in a greenhouse, install exhaust fans, circulation fans, and other equipment to promote air circulation. Place the Phalaenopsis in a well-ventilated position, such as near a window or an air vent, but avoid strong wind blowing directly on the plant.

Understanding the temperature thresholds for high-temperature dormancy in Phalaenopsis and doing a good job of care during dormancy in terms of light, water, fertilizing, and ventilation are the keys to helping Phalaenopsis safely get through high temperatures and grow healthily. As long as we master these key points, we can provide a suitable growing environment for Phalaenopsis in different seasons.
