Yes, a willow tree will almost certainly grow back from a stump. Willows are among the most aggressive resprouters in the tree world, and cutting one down without treating the stump is essentially pruning it rather than killing it. New shoots can appear within weeks of cutting, and those shoots grow fast, often reaching 6 to 9 feet in a single growing season.
Why Willows Regrow So Aggressively
Willows belong to a group of trees that evolved to regenerate from damage. When you cut a willow down, dormant buds sitting just beneath the bark activate and push out new shoots. The stump still has a fully established root system underground, which means all the water and nutrients that once fed a full-sized tree are now fueling a handful of small sprouts. This gives them an enormous growth advantage over a tree starting from seed.
This ability is so reliable that people have harvested willows this way for centuries. The practice, called coppicing, involves cutting willow stems to the ground and letting them regrow on a repeating cycle. Commercial willow plantations typically harvest regrowth every two to three years on fertile sites, and a single stump (called a “stool”) can keep producing new stems for decades. Research on shrub willows found that sprouts from cut stumps reached nearly 9 feet tall in one growing season, with the strongest regrowth coming from stumps that were roughly 1 inch in diameter at the time of cutting.
What to Expect After Cutting
If you’ve recently cut down a willow and you’re hoping it comes back, you probably won’t wait long. Multiple shoots will emerge from around the edges of the stump where the bark meets the wood. You’ll likely see dozens of them rather than a single new trunk. Over time, a few dominant stems will outcompete the rest, and within a few years you’ll have what looks like a multi-stemmed tree growing from the original stump.
The speed of regrowth depends on a few factors. A stump with a large, healthy root system will produce more vigorous shoots than one from a stressed or diseased tree. Willows cut during winter dormancy tend to send up strong growth the following spring, while those cut in midsummer may sprout more slowly. Soil moisture matters too. Willows thrive near water, and a stump in consistently moist ground will regenerate faster than one in dry soil. On fertile, well-watered sites, growth can be especially aggressive during the first two years after cutting, then gradually slows as the canopy fills back in.
If You Want the Stump to Stay Dead
Many people searching this question aren’t hoping for regrowth. They’re trying to get rid of a willow and want to know if the stump will cause problems. Washington State University Extension specifically names willow as one of the most common offenders for unwanted stump sprouting, alongside cottonwood, black locust, and tree of heaven.
The key to preventing regrowth is treating the stump with a brush-killer herbicide immediately after cutting. Paint the product directly onto the freshly cut surface, concentrating on the ring of living tissue (the thin green layer just inside the bark) all the way around the stump. Timing matters: the sooner you apply after cutting, the better. The cells in that ring are still alive and will absorb the herbicide and transport it into the root system. This can be done any time of year.
If the tree was cut down days or weeks ago and you didn’t treat it, you have two options. If the stump hasn’t started sprouting yet, re-cut it with a chainsaw to expose fresh living wood, then apply the herbicide to the new surface. If sprouts have already appeared, let them grow until they’re in full leaf and actively growing, then spray them with a non-selective brush killer. The leaves will absorb the herbicide and move it down into the roots. You may need to repeat this process, because willow root systems are persistent and a single treatment doesn’t always finish the job.
Roots and Suckers Beyond the Stump
Even after the stump itself is handled, some willow species send up new shoots from roots that extend well beyond the trunk. These suckers can pop up several feet from the original tree, sometimes appearing in garden beds, lawns, or near foundations. If you see these, treat them with the same brush-killer herbicide while they’re actively growing and have plenty of leaf surface to absorb it. Mowing or cutting suckers without chemical treatment will only encourage more of them, since the root system responds to damage the same way the stump does: by sending up more shoots.
For anyone who wants regrowth but in a more controlled form, you can manage a willow stump by thinning the sprouts each year, selecting three to five of the strongest stems and removing the rest. This channels the root system’s energy into fewer stems and produces a more attractive multi-trunk tree over time.
