Mell What triggers trees to go dormant?

Otherwise, the tree would die from a lack of water resources due to frost, or not produce enough energy to sustain itself. In order to survive through the winter trees must “fall asleep”.
How do trees know to go dormant?
The tree stops growing. Leaves are drained of nutrients and shed. And the vulnerable points of growth – where they have stem cells that can make new leaves and twigs – are encapsulated in a winter bud consisting of hard bud scales. Thus the tree can be dormant for months, withstanding frost and snow.
