Winter dormancy
Winter dormancy is a natural process where many plants slow down their growth and conserve energy during the colder months. This is not a disease but a seasonal adaptation.

What you see
Winter dormancy is a natural and essential phase in the lifecycle of many perennial plants, shrubs, and trees. During this period, plants reduce their metabolic activities to conserve energy and protect themselves from harsh winter conditions. This process is triggered by shorter daylight hours and cooler temperatures. Unlike diseases, winter dormancy does not harm the plant but is a survival mechanism that allows plants to thrive once favorable conditions return. It is important to recognize that this is a normal part of the plant's lifecycle and not a cause for concern.
Symptoms
- Leaf drop
- Yellowing leaves
- Stunted growth
- Wilting
Why it happens
The underlying cause of winter dormancy is the plant's response to environmental cues such as reduced daylight and lower temperatures, which signal the approach of winter.
