Do Trees Grow Roots During Dormancy​?

Caring for trees during the winter is different from other times of the year. Many types of trees, such as oaks, birches, and maples, experience dormancy during the coldest months of the year. 

Let’s dig into the details of whether trees grow roots during dormancy, when they grow fastest, and whether a tree stump can still grow roots.

Do Trees Grow Roots While Dormant​ in the Winter?

Whether trees grow roots during dormancy depends on the ground’s temperature and the overall climate. When the soil temperatures reach below freezing, root growth stops, and it won’t resume until the ground temperature rises above the freezing point. Although trees can grow roots during dormancy if climate conditions are right, the growth is typically much slower than other times of the year.

What Is Dormancy?

Dormancy is a period when plants and trees enter a state of “rest” and temporarily stop growing. It is caused by reduced temperatures and sunlight, occurring during late fall and winter. When a tree enters dormancy, it conserves energy and resources, allowing it to survive the harsh conditions of the winter season and prepare for the growing season.

When Do Trees Grow Roots the Most?

Since deciduous trees enter dormancy during the winter, they tend to grow most during late spring and early summer. If temperatures remain above freezing, some trees can grow roots into the fall, too. However, as the temperatures get colder, root growth slows down.

To care for a growing tree during dormancy, add a layer of mulch around the tree out toward the drip line, which can help regulate the ground temperature and protect the tree’s roots.

How to Get Rid of Tree Roots

There are many methods for killing tree roots, including chemical herbicides, manual removal, and root pruning. It’s best to hire a tree service professional to remove pesky root systems, especially if they’re interfering with your landscaping or sidewalk, because it will require specialized tools and experience.

If you have tree roots growing out of a stump leftover from a cut-down tree, you’ll need to remove the stump entirely to get rid of the troublesome roots. Hire a stump removal company near you to get rid of the stump and remove the roots to prevent potential damage. The amount it will cost to remove a stump and the roots varies depending on its size, location, and removal method used, but you can expect to pay between $200 and $700.
