Thank you everyone, so after reading everyone's advice I thought I would first try dyzzypyxxy advice that gave me the idea. I am not so keen about installing lattice BUT to stretch wire as a lattice. So I will add short poles to the existing rail to get it to 6' from the ground. Secure, then get wire and attach to each pole making something for the ivy to climb on. I will fertilize the area to give some nutrients for fast growing or encouragement for the existing ivy to grow faster and healthier and add new spots of ivy plants where needed. Yeah it needs a lot of help. Any advice on fertilizer for the ivy? I heard 10-10-10 would work?
