Maple trees with girdling roots

10 years ago

last modified: 10 years ago

We bought this house 6 months ago and knew the trees were not in great shape. We had them both trimmed and the guy who did it told us that he would be back to take them both down someday and wondered if we wanted it done right now. The roots are girdled and very exposed but the tree is full of leaves and seems healthy for now.

I am adding some pictures of the worst roots. What can be done to "help" the trees and should we remove the soil around them and add mulch to help the roots "breathe"? Any help would be appreciated. I don't want to loose these big old shade trees if I don't have to but I also don't want them to fall on my house either.

That tree is obviously very well established and with numerous decades under its belt. While never a good thing, if those girdling roots were to be a concern, that concern would have manifested already with stunted growth and lack of foliage development and the tree would be already in decline. It doesn't appear to be suffering any of those conditions :-)

I would guess at this length of time after planting, there are more than enough structural roots radiating out from the trunk to provide anchorage and with them all the fine feeder roots that support the tree with moisture and nutrients. If you were to peel back the sod and soil to expose the entire root system, I am sure you would find large roots extending well out beyond the tree canopy - I doubt the tree would have survived this long without them. There is nothing you need or should do at this point - the tree is self-sustaining.

If you have questions about its structural integrity - the possibility that it could blow down in a storm - then you may want to have the tree examined by a certified arborist who is skilled in hazard assessment. This is not your average Joe Blow tree-trimmer but a highly trained tree professional. There is a BIG difference!!

Oh, wow.

What advice did you get? Or did you take them down?

I noticed my Brandywine was girdling a year or two ago. I got it as a 2-year old and it was probably 12 at that point.

Given the fact that I had nothing to lose, I cut the girdling root. But it was nothing like those sad babies!

It's such a shame that the pop trees in the ground in those wire baskets or burlap bags. Thank you HGTV. My ex-DH ignored my concerns and convinced me a Red Sunset would be fine in its wire basket. It's struggled since day one and I know it'll eventually girdle itself.

They are still standing! We haven't had anyone come forward with any advice other than removing them. I love the shade they provide but I do worry about all the storms we get here. I am sure nothing can be done since the trees are quite old and so severely girdled. I was hoping someone on here may have some advice for prolonging the inevitable. Thanks for the comments and I hope that your maple doesn't suffer the same fate.

My neighbors have a Norway maple with roots almost exactly like this. The thing is monstrously large, and healthy as can be. It's probably 60' tall and solid as a rock.

Like Gardengal said, I think this tree is showing you how well its doing. I'd leave it alone.

Thanks for the feedback. We feel the same way. The trees seem really healthy and have been there for over 40 years. I think we will have a professional come take a look to put our minds at ease, since we do get very high winds here. Thanks again.

It astonishes me that the immediate answer is to take it down. To me, that shows someone who really knows little to nothing about a tree.

If they were to start showing decline, or some element of not being healthy? That would be different. I'm not taking mine down (either) just because they're not perfect. They're healthy and big. Or at least the Brandywine is. The Red Sunset has suffered borers, that root system and God knows what else. The thing is, it keeps trying to heal itself and you can SEE that!
Good luck with these beauties.
