I have a fenced area for my dogs, approximately 30x40ft with 6ft chainlink. I'm sort of wishing I spent the money and got stockade because this chainlink is unsightly! I'm looking for ways to disguise it, and the most cost efficient and natural way seems to be climbing vines. I originally looked at different types of Ivy, but they all seem to be poisonous. Star Jasmine would be beautiful and I love the fact that it's a flowering vine but, again, poisonous. I am looking for a fast growing evergreen vine that will not be toxic to my pups or chickens if they decide to eat it. The fence is in a full sun area. Any ideas?
