I am trying to get ivy started
growing up the brick on the back of my home. However, there are a porch (first floor) and balcony built across the entire width of the building, so I can't
plant the ivy in the ground and instead have it in planters next to the wall. Will this work? Will I eventually be able to remove the planters all together once the ivy is established on the wall or will it always need this soil beneath it? Can it survive outside in the winter (I am in
zone 5) if it is not embedded in the ground? Thanks.
