Weeds in walls

[Warren R Sole]

So you couldn't use it? That's a shame

It was about eight feet up the wall and still difficult to reach from the roof due to an unstable skylight.

At least rosemary is useful but I bet they were pleased!

I used to live in a leasehold flat and had access to a concrete roof. I planted rosemary seeds taken fro a plant in a council border and some years later it self seeded into a high wall around the pub beer garden and was itself flowering.

Thanks Jane and Ameno.

It's good to know what it is and that it isn't damaging but I will Let the landlord know.

I'm looking to move though, once hibernation is over.

I’d let the landlord know because if it was my house I’d get it sorted & removed so it’s not growing through the house,it sounds damaging.

If it's ivy-leaved toadflax then it won't damage anything. It's tiny, as are its roots. It's only growing in pre-existing cracks and crevices, and won't make them any larger.

If you want damaging, some houses near me have fairly sizeable buddleia bushes growing out of the first floor windowsills (in the actual brickwork). Now that's damaging.

Yes he might not know it’s that bad,buyers wouldn’t be keen on seeing that if he’s selling. It sounds like it’s growing everywhere,take photos maybe,if there’s any damage to anything,you can’t be held liable,I don’t know but I’d take photos incase of anything.

[Warren R Sole]

It is through the house, under the patio, growing out of the drains, everywhere, even popped out of the wall at the front where there is no garden at all.

He's trying to sell it and I think he may know about it but he should be made aware I think.

[Warren R Sole]

Btw, that's the stuff.

It is everywhere; under and through my house.

[Warren R Sole]

OK thanks Mothhawk.

I'm really adept at doing nowt!

If the stems of whatever plant it is are soft, it won't be damaging the wall, just taking advantage of crevices where the mortar has decayed. I'd leave it to grow and provide more habitat for critters and creatures.

[Warren R Sole]

Thanks to you both. I'll look up a picture of it.

Should I assume roundup would do it good?

[Martin H]

Sounds like it might be ivy-leaved toadflax?

Could be various things. Ivy leaved toadflax or herb robert would be my first suggestions.
