Watching "Fixer Upper" on HGTV. The house they are working on has a lot of damage & rodent infestation from ivy growth on the side of the house.
Other than the concept that it looks "charming," is there any real reason why any home owner would plant ivy to grow up a trellis (or side) on the house? In the past, did it keep homes cooler, or... something?
Just trying to figure out what the original purpose of ivy-covered English or New England homes might have been.
