Are vines on masonry wall OK?

[Richard Mangold]

Todays local newspaper (Chicago Tribune House & Home section) stated that "ivy planted on a brick wall or chimney poses no threat at all , unless the wall has structural flaws already, such as soft or loose mortar". Do you agree with this? I thought that no vegitation on a wall is beneficial to the wall.

Its arguable...

IMHO, I don't like it, because just like water and plants can eventually breakdown a granite mountain, they will do the same to bricks and mortar (only faster). The plants will hold moisture that will wick through the bricks, in the winter it will freeze and crack. Not to mention it makes a great highway for vermin to make their way into the home.

After you get interviewed from some newspapers, you will understand not to believe what you read is entirely true. Sad but true.

[ROBERT W. NEWLAND, JR.]

Not good. Over time, will cause damage.

This is a great question, but probably no definative answer??

In the northwest, vegatation near or touching the house is considered a no, no

In California, you see quite commonly, vegitation next to the house, and all sorts of vine like vegatation up the walls of stucco homes.

So, what is the "rule of thumb" or opinions of "do you call out vegation/vines on houses"?? If so, why?

Hope to hear your thoughts soon, before I get paronoid and go out and cut that nice looking,flowering, sweet smelling, vine from my stucco!

This article might help shed some light on the subject.

Did he really say "no threat at all" or is that paraphrasing?

If he said "no threat at all," that begs the question, "threat to what?"

If he means that the ivy and its roots won't damage the brick and mortar, he's dead wrong. The time frame for the damage occurring depends on the type of ivy. English ivy can be extremely destructive, as can the philodendrons. Poison ivy not so much, but it has other problems that one has to deal with.

I haven't seen any vines growing on stucco walls in my neck of the woods, but I have seen many vines growing on lattice work next to stucco walls to provide that effect.

Thanks to all for the comments. I put quotes around his exact words.

Seems to be written by a "plant guy".

Not only does ivy send roots into the structure (especially soft mortar) it is a conduit for WDI. It's one of the easiest ways for wood destroying insects to enter the house structure.

[dbelmont]

I don't recall ever finding an Ivy (and other climbing type vine) wall that wasn't being damaged by the plant. So my opinion based on that is that clinging vines will (not might) damage the wall over time.

From the article I'd say the author is big on vines and way short on building science.

But I've had clients who loved the vines and were perfectly happy to ignore my opinion on this. A few have eventually had to make repairs but so far no one has tried to say I didn't make it clear that vines on house wall is a bad idea.

[William J. Decker]

In our area, bad. Masonry needs to dry. We have a wet, humid climate in the Chicago area and vines and ivy do not allow for proper drying.

I always call it out.

Wonder how I could contact this guy?
