How do trees survive winter? They have a few tried and true techniques.
Most trees drop their water-loving leaves in fall so they can conserve as much water as possible before winter starts. Also, trees undergo a few fascinating biological changes to stop their cells from freezing.
But despite these efforts, winter weather is relentless. There’s always a chance your tree will start spring with some sort of injury from the cold, a.k.a. winter dieback.
WHAT IS WINTER DIEBACK?
Sometimes parts of a tree don’t make it through winter. That’s called winter die-off, or winter dieback. A limb here or a group of branches there might freeze to death, meaning they won’t put out new growth in spring. But don’t panic! Winter die-off does not mean your tree is a goner. Trees can absolutely bounce back from winter injury.
