I often see retaining walls. If I had to guess a percentage I would say that about half have some movement. In this case, it's a darn good thing there is a retaining tree!
This tree has been on the job a long time!
I see fences all the time that are held up by vines and plants.
I see sheds all the time that are held up by vines and plants.
But I have seldom, if ever, seen a retaining wall held up by a tree!
And this wall frames a working driveway and garden!
This tree is important!
Another couple of years and maybe another one will be needed. Maybe two or three!
They should think ahead!
Let's see, what kind of tree would be best?
Should this wall be repaired? Doing so might actually harm this tree! And then it would have no reason to live.
My recommendation: sometimes things look bad, but really might not be! In this case, though, a couple of more 40 year-old trees might be advisable!
Actually you can see that the wall is crumbling around the tree. How much longer will the wall last? I am being tongue in cheek about it being held up well and that only a couple of trees are needed. When this collapses it will be a mess, and the driveway will not be usable. It's probably best to get a real wall there now! I don't know who has responsibility for the wall, but when replaced, obviously, it will need a good guardrail!

Anne - codes change but I suspect this wall would have required a guardrail when it was installed. It is high. It is also at the edge of a big property and not in town, so no County person has probably seen it. But again, I don't know who the all belongs to!
Behind the wall? I can do that post. I'll think about it...
Jay - I have not seen that in our area, but am pretty sure it does exist somewhere in the greater Jacksonville area - amazing how homeowners can become complacent about things like that, isn't it?
That is something that has happened a little bit each year for a long, long time Carol! They may not even notice!
Good morning, Jay.....cha ching, cha ching, cha ching.....now's the time to find an unemployed mason who will work for short money....
Well I guess it's a opportunity to make a pretty wall, right? Good thinking on the handrail as that can be a real safety hazard.
Jay - Few of the "older" retaining walls were built correctly; and as time passes their shortcomings become apparent. Perhaps some good old kudzu could help.
Miss T (from the calendar department, on the desk even now!) - not my problem! But I think that wall would be a pretty penny, not short money.
Debbie - I would have been doing handflips off that wall as a kid. Watch Mom!
John - I said in the post that I have seen many a structure held up by plants! That is certainly the 60s - 70s way of doing a retaining wall! See all the weep holes?
Jay, in your photo it looks like there is one tree fighting to hold the wall up and another tree fighting to knock it down :)
Jay - "a huff and a puff" that retaining wall will be blown down!
That leaner on the right is certainly part of the problem with the wall Charlie. It's only about 5' away.
Eric - another really wet year and that might be true! Hard to predict anything with retaining walls though.
I see a lot of this type of retaining walls in the older part of the city. I've wondered for years not if, but when were they going to fall onto the sidewalk. A lot of them around here have those big trees in the yard above the wall. Scary stuff.
Jay -- yes, just planting more leaning trees won't help much with more soggy weather - unless there are some retaining bars between the trees. Nope, new wall, properly constructed and drained is really the only answer - short of removing lots and lots of dirt.
Mike - I see these all over town too! And, as John said above, this type is very old school.
Steven - of course I was being silly and tongue in cheek in recommending more trees. Surely a new wall is necessary here!
Jay, You are so funny. I get a real kick out of your posts.
Thank you Katie. You mean my tongue-in-cheekness comes through now and then?
Tear down this wall Mr. Seller. That phrase some how sounds familar to me ;)
Jim - I never did find out who the wall belongs to! Even if it is the house to the side, it is still an issue for the buyer.
I always hate reporting on retaining walls. How long will they last? Who knows. When I moved in to my last house about eight years ago, one of my neighbors had a retaining wall by the road that I was sure would collapse any day. After walking by it every day, I found it never moved an inch.
Hi Jay,
Good thing this was a strong tree. Maybe that was the plan from the beginning and the orginal owners had the good sense to pick a sturdy one!
Hope your 2011 is ending well and your 2012 is a healthy, happy, and successful year for you!

Reubs - I think had this tree not been there that wall would still not be. On inspections people ask me about how long a wall will last I say, "One really wet month or maybe twenty years, who knows!"
DeeDee - that was a really old black walnut with a cleft near the base! Strong tree. Thank you and the same bakattcha! I like the new photo too.
