We have a stone house and think it would look really nice to have ivy on part of it. After much research, I found that Baltic Ivy would be the best, considering the location (west facing stone wall about 30 ft high). But I just have to clarify, would it take the whole wall over? when do we prune it if necessary? is it safe of masonry work? will it die from the heat of the sun? when do we plant it? Thank you for any responses!
