Have you ever had a tree removed from your property and wondered if it will grow back from the remaining stump? It's a common question for homeowners and landowners when removing trees. The idea of new life sprouting from an old stump can seem almost magical, but it is possible for many tree species to regrow in this way naturally.
In this article, we'll explore the science behind tree regrowth from stumps and discuss the factors that determine whether or not a particular tree stump will send up new shoots. We'll also provide tips on both encouraging and preventing regrowth, depending on your goals for managing the site where the tree was removed. While tree removal is sometimes necessary, it can also represent an opportunity for renewal. Understanding the regrowth process allows you to work with, rather than against, this natural cycle.
When a tree is cut down, whether by a professional arborist or a weekend DIYer, a stump is left behind. The tree itself doesn't just disappear into thin air once it's cut. The stump that remains is the base of the trunk of the tree that was cut.
Depending on the size and species of the tree, the stump can range from just a few inches tall to several feet high. It will be approximately the same diameter as the trunk of the tree was before it was cut. The visible portion of the stump is connected below ground to the tree's expansive root system.
So while the aboveground portion of the tree is removed through cutting it down, the stump and roots left behind beneath the soil are still very much alive. This means that regrowth is possible in many cases if the conditions are right. The stump contains dormant buds and stored energy that can produce new growth under the right circumstances.
Yes, under the right conditions, a tree can regrow from a stump. When a tree is cut down, leaving just a stump behind, there is a possibility that the stump will sprout new growth if enough of the trunk and roots remain intact. The ability of the stump to regenerate depends on several factors, including the tree species, the health of the remaining stump and roots, the height at which the tree was cut, and other environmental conditions.
In general, many trees can regrow from stumps through a process called coppicing. Coppicing refers to the natural regrowth of shoots from the stump or roots of previously harvested trees. When a tree is cut, certain hormones are activated that stimulate the growth of new shoots from any remaining meristem tissues in the stump or roots. As long as there is sufficient living tissue in the stump and a large enough root system below ground, new growth is possible. However, the regrowth rate and extent can vary significantly depending on the specifics of each unique situation.
There are several key factors that determine whether a tree stump will regrow or not:
Type of Tree - Some tree species, like aspens, eucalyptus, and Kauri (Agathis australis), are more likely to regrow from their stumps than others. Trees that tend to sprout from stumps have dormant buds beneath their bark or roots that can generate new growth when the trunk is cut.
Tree Health - Healthy, vigorous trees have the best chance of regrowing. Trees under stress or in decline are less likely to regrow well from a stump. Make sure to maintain trees well before cutting them.
Time of Year - The season when a tree is cut affects regeneration. Cutting in late winter when the tree is still dormant allows new sprouts to emerge in spring. Cutting in summer may inhibit regrowth.
Stump Size - Larger stump diameters give more nutrients and stored energy for regrowth. Smaller stumps have less capacity to support new shoots. Leave at least 3-4 feet of trunk for the best regrowth potential.
Site Conditions - Growing conditions like soil quality, moisture, shade or sun exposure affect the ability of a stump to send up new shoots. Favorable conditions support regrowth while harsh, dry sites may hinder it.
Pruning -Occasional pruning of side shoots on stump sprouts channels growth to the main leader, improving sprout form. Never prune back the leader.
There are a few techniques you can use to encourage a tree stump to regrow. The most important is making sure the stump is healthy and undamaged. Cut the tree off smoothly and cleanly near ground level. Any jagged edges or wounds make it harder for new shoots to emerge.
Applying fertilizer to the tree stump can speed up regrowth. Choose a balanced organic fertilizer and apply it around the stump and the rootzone area. This provides nutrients to stimulate new growth. Water the stump after fertilizing to help carry nutrients down to the roots.
You can also use rooting hormone, a natural or synthetic plant hormone, to encourage regrowth. Dip the top of the freshly cut stump in the powdered hormone. This signals to the plant tissue to start dividing and growing. Rooting hormones are available at most garden centers.
Finally, protecting the stump from harsh weather and keeping it moist will improve the chances of regrowth. Cover the stump with a plastic tarp or wood planks if in a very exposed area. The cover retains heat and moisture while sheltering from wind. Regular watering, especially in dry periods, is also important. With a little encouragement, you can often get a tree stump to sprout again.
If you don't want the stump to regrow, there are a few techniques you can try to prevent new shoots from appearing.
Painting Stump with Herbicide
One of the most effective ways to stop regrowth is to paint the freshly cut stump with an undiluted herbicide, also called a tree killer. Glyphosate is the most commonly used herbicide for this purpose. When you cut the tree down, apply the herbicide immediately to the outer area of freshly exposed wood. Follow the manufacturer's instructions for application. The herbicide will soak into the living cells in the wood and roots to prevent regrowth.
Grinding Down Stump
You can also prevent regrowth by grinding the stump down to below ground level, and removing all of the living wood. Use a power stump grinder to grind away the stump until only the soil remains. Go at least 6 inches below ground level to remove all the stump material that could sprout new growth. Grinding also destroys the stump's root system so no new shoots will emerge.
How long it takes for sprouts to emerge from a tree stump depends on several factors, including the tree species, time of year when cut, overall health of the tree, and growing conditions.
In general, most tree species will start sending up sprouts within a few weeks after being cut down. The sprouting process begins when dormant buds left on the remaining trunk and roots detect an increase in light and warmth. This triggers the buds to start growing.
For some fast-growing tree varieties like willows, cottonwoods, silver maples, and ash trees, visible sprouts may emerge in as little as 2-6 weeks after cutting the tree down. Slower growing trees like oaks, hickories, and beech may take 3-4 months for sprouts to visibly appear.
Evergreen trees also tend to be slower, taking anywhere from 1-2 years for new sprouts to emerge from the stump. Conifers like pines, spruces, firs and cedars regrow from epicormic buds under the bark or latent adventitious buds at the crown. This is a slower process than deciduous trees.
The time of year when a tree is cut down impacts regrowth timelines as well. Cutting in early spring just before growth starts means less stored energy to power regrowth. Cutting in late fall allows food reserves to accumulate over winter. For fastest regrowth, late winter is optimal.
In summary, visible sprouts generally emerge in 2 weeks to 4 months depending on species, season, and growing conditions. The stump may continue sending up new shoots for several years as it tries to regrow a canopy.
Proper care can help ensure the regrowth from a tree stump thrives. Here are some tips:
Pruning - Pruning the new shoots encourages the plant to grow into a healthy tree. Prune off any dead or diseased branches. Also prune any shoots that cross or rub to allow space and airflow.
Watering - New regrowth needs sufficient water, especially in times of drought. Water deeply at the base of the plant once or twice per week.
Fertilization - Applying a balanced organic fertilizer can provide nutrients to support growth. Use one labeled for trees or shrubs.
Mulch - Mulch helps retain moisture and suppresses weeds. Spread 2-4 inches of bark, leaves or wood chips around the base of the stump. Keep mulch a few inches away from the trunk.
Pest Management - Young trees can be susceptible to pests like borers, scale and mites. Monitor for signs of infestation. Use organic sprays if needed.
Protection - Fencing, netting or tree guards can protect tender regrowth from animal browse and lawn mower damage.
Providing ongoing care creates optimal conditions for a strong sapling to establish and mature into a healthy tree from the old stump.
While some tree stumps may sprout new growth, this outcome isn't guaranteed. Fortunately, there are other options for what to do with a tree stump if regrowth doesn't occur or is not desired.
One alternative to waiting for a stump to regrow is to plant a new tree in its place. This allows you to choose a species that better fits your landscape needs or aesthetic preferences. When planting a new tree:
Choose a site near but not directly over the old stump. Digging up the stump would disrupt large areas of roots from the old tree. Planting adjacent to the stump prevents this.
Amend the soil with compost or other organic material to improve conditions for the new tree.
Select a tree suited for the sunlight, soil, drainage, and other conditions in that area. Native species adapted to your region are good choices.
Prepare a wide planting hole and follow instructions for planting properly at the right depth. Stake the new tree for support if needed.
Water the newly planted tree well and mulch around it. Provide regular water for at least the first year.
With proper selection and care, a new tree can establish quickly and begin providing shade and other benefits.
Rather than let a stump go to waste, another option is to turn it into a work of art, a planter, or even furniture. Removing the bark and sanding the stump reveals unique wood grain patterns. You can:
Carve the stump or decorate it with paint, tiles, stones, or other materials. Consider turning it into a statue, bird bath, or other decorative piece.
Hollow out part of the stump and turn it into an unusual planter for flowers. Line it with plastic to prevent rotting.
Flatten the top of the stump and use it as a small table or chair. Short stumps work well for this.
Attach table legs, casters, or other hardware to make the stump into a movable side table or plant stand.
With some creativity, a stump can become a functional or artistic garden feature rather than an eyesore. Just avoid cutting into any new growth emerging from the sides.
When should you call in a professional for stump removal? Here are some key times when it's best to let the experts handle it:
Large stumps over 12 inches in diameter. The bigger the stump, the harder it will be to remove yourself. Professionals have the heavy duty tools to grind large stumps efficiently.
Stumps in hard-to-access spots. If a stump is near buildings, fences, or other obstacles, it can be tricky to maneuver equipment around it. Professionals have the right tools to get the job done without damage.
Stump is growing back. If you cut down a tree but new shoots are emerging from the stump, call a pro to finish removing it. They can apply herbicides to prevent regrowth.
Multiple stumps to remove. Removing several stumps takes special equipment and know-how. A professional company can remove all your stumps in one visit.
Roots are spreading. Tree roots often spread wider than the trunk. Professionals can remove the entire stump and root system.
Time constraints. Stump removal takes patience and effort. If you need it done quickly, hire a company to take care of it efficiently.
Concerns about chemicals. Stump removal often involves herbicides. If you prefer to avoid chemicals, hire a company that uses eco-friendly techniques.
Unsure about safety or techniques. Improper stump removal can lead to accidents. Professionals have the training and experience to remove stumps safely.

Not all tree species can regrow from a stump. Some species, such as aspens, eucalyptus, and Kauri (Agathis australis), etc, are more likely to sprout than others. Their ability to regrow depends on the presence of dormant buds under the bark that can generate new growth after the tree is cut.
The ability of a stump to regrow depends on factors such as:
Sprouting time varies significantly, depending on factors like the tree species, season of removal, tree health, and environmental conditions:
To promote regrowth from a stump, ensure it is healthy and undamaged. Cut the tree cleanly near ground level, apply a balanced fertilizer around the stump and root zone, dip the freshly cut stump in rooting hormone, and protect the stump from harsh weather.
To prevent regrowth, you can either apply tree-killing herbicides, like glyphosate, immediately after cutting down the stump or grind the stump down to about 6 inches below ground level using a power stump grinder to get rid of seeding material.
If a stump doesn't regrow or doesn't suit your preferences, you can plant a new tree nearby, turn the stump into art or furniture, or hire a professional for stump removal services.
When a tree is cut down, the remaining stump holds the potential for regrowth. However, whether or not the stump sprouts depends on several factors.
Certain tree species, like aspen and eucalyptus, are more likely to regrow from the stump. The size of the tree, the time of year it was cut, and the cutting technique also play a role. Proper care of the stump and patience are key to giving regrowth the best chance of success.
If regrowth is desired, the stump can be encouraged through pruning cuts and hormone application. But if preventing regrowth is the goal, herbicide treatment of the stump is recommended. Either way, the regrowth process is relatively slow, taking 1-3 years on average.
While stump sprouting offers the possibility of a replacement tree, alternatives like planting a new tree may be preferable in many cases. With careful consideration of the species and site conditions, regrowth can be a natural way to regenerate a small tree from an existing stump.
