I am having trouble getting our Ivy to climb our brick on the outside of the house. I would rather not use a wood trellis. The Ivy is growing like crazy but is having trouble grabbing the brick. Any suggestions?
You don't want ivy to grow on bricks, it's bad for the mortar.
At least thats what I've been told and just thought I'd let you know.
Maybe someone else knows more then me and can tell you more.
According to DH, my resident English ivy expert, it really depends on the type of brick you have. The brick needs to have crevices that the roots can grab onto.
We had English ivy on our house in Virginia and it does grab on the bricks first and then the mortar. It didn't really damage the brick or mortar just by growing there. The damage really occurs when it dies or you have to remove it for another reason. It's almost impossible to remove all the ivy so if you or someone else wants to remove it in the future there will always be little bits of dead ivy outlined in the brick.
Bobbi p used a no drill trellis you can see in her post here if you scroll down.

I heard it was bad for the mortar too but I grew up in a 300 year old brick house covered in ivy so I guess it isn't too bad.
I agree, it is impossible to remove completely once you want it gone. Even with a heavy duty power washer. Also, it sends vines up through any small gaps in the wood window frames and roof soffits which doesn't seem like a good thing.
