Do Tree Roots Die After Tree Removal?

The February blizzard brought down trees across southeast New England, with Massachusetts peaking at 37 inches of snow. Whether your tree in Hopkinton, Upton, or Milford came down because of a storm or a planned removal, the stump and roots stay behind. The question then becomes: Do tree roots die after tree removal?

What stays in the ground affects what you can plant, build, or pave on that spot, with some species sprouting up and requiring annual cutting back.

Key Takeaways

• Roots lose their food source when the tree comes down and begin dying back, though not overnight.
• Red maple, Norway maple, black locust, and tree-of-heaven can sprout back, so check your species first.
• Small roots break down first, while large roots and stumps can linger for many years.
• Grinding is an add-on to tree removal, and whether you need it depends on your plans for the spot.

Fine roots die back first, while large roots and thick stumps can linger underground for years.

Do Tree Roots Die After a Tree Is Removed?

Yes, for most trees, but it’s a gradual process. Leaves make the sugars that feed the root system, which means taking the tree down also means cutting off that food supply. From there, the roots die back in stages:

• Fine, water-absorbing roots tend to go first.
• Larger roots live off stored energy reserves and hold on longer, but how long is not well established.
• Once roots die, they begin to decompose underground, a separate, slower process.

Cutting sprouts back every year keeps them from growing into multiple trunks.

Will the Stump or Roots Sprout Back?

Some will, depending on the species. For many trees, sprouting from the stump or roots is a core survival strategy. In any yard, a species like that can become a major maintenance issue, so the following species are the ones you should look for:

• Red maple, other soft maples, and boxelder are among the species that cause the most trouble in urban settings.
• Norway maple is widespread across New England, and control options include grinding out the stump or clipping off regrowth.
• Black locust can sprout from roots far from the tree, even after you grind out the stump.
• Tree-of-heaven, cottonwood and poplar, willow, linden, beech, red oak, crabapples and other rose-family trees, and green ash are on that same list.

What to Watch For and What to Do

Take a look at the stump and the area around it for new shoots. If you see some, you’ll have to cut them back every year because, when left alone, sprouts can grow into multiple trunks leaning away from each other, which can become hazardous.

If sprouts keep appearing far from the stump, or come back faster than you can keep up with, bring in a tree care professional.

How Long Do Tree Roots Take to Decompose?

Roots and stumps break down slowly, with small roots going first. Then, large roots and thick stumps can take many years to break down, depending on size and species. That said, drilling holes in the stump, adding slow-release fertilizer, and mounding soil over it can speed up the decaying process.

Fungi do most of the breaking down, and some root rot fungi can survive on stumps and dead roots for (in some cases) over 15 years. If the tree was removed because of root rot, it may be worth considering grinding the stump.

Does a Tree Stump Have to Be Removed?

No, a tree stump doesn’t have to be removed; whether or not it goes depends on what you plan to use the spot for. When you do need to remove it, American Climbers offers stump grinding as an add-on to tree removal, not as a standalone service. Grinding out the stump and large roots can also greatly reduce sprouting from the stump.

Questions to Guide Decision-Making

There are three questions that can guide the decision-making process about whether or not the stump should go:

• Are you planting, building, or paving on that spot soon? If so, grinding should be the next move.
• Is the tree a species that sprouts? To combat sprouting, grind the stump or commit to cutting sprouts yearly.
• Is the stump a tripping or mowing hazard? If so, grinding makes sense.

If none apply to you, the stump is okay to stay if you so choose.

Frequently Asked Questions About Tree Removal and the Roots

Can old tree roots damage sidewalks, driveways, foundations, or pipes?

Once a tree is removed, its roots generally stop growing, so they no longer add pressure on pavement or pipes, though sprouting species can send up new shoots. Roots that already lifted pavement stay in place until they decay. American Climbers explains in more detail how tree roots damage foundations, plumbing, and walkways.

Is it okay to leave tree roots in the ground?

Usually yes. Grinding removes only the stump and large roots, so the rest of the root system stays in the ground and breaks down on its own.

Why are mushrooms growing where my tree used to be?

Some wood-decay fungi, such as Armillaria, send up mushrooms at the base of stumps from late summer to fall as they break down old wood. Mushrooms near a stump or old roots are a sign that decay is underway.

Can I use herbicide to stop stump sprouts?

Some herbicides applied to a fresh stump cut can control sprouting, though some need repeat applications and every product must be labeled and registered for use in your state. A few can also pass to nearby trees, especially the same species, through root grafts, so ask a licensed applicator or your local Extension office.

How low should the stump be cut?

Cutting the stump at ground level lets you control sprouts by mowing. If you plan to leave the stump, ask the crew about cutting it that low.

Grinding takes out the stump and large roots, which also greatly reduces sprouting.

American Climbers Can Remove Your Tree and Grind Your Stump

If you’re in Hopkinton, Upton, Milford, and the surrounding area and ready for tree removal, request a quote from American Climbers and be sure to ask about adding stump grinding to the job. If the tree’s still standing but looks hazardous, start planning hazard tree removal before winter now.
