When it comes to the outside coverings for city walk I always wondered why the ivy has not covered the meshing. Does any one know why 11 years later the ivy only covers about the same area that it did after the first year of growth? Have they tried other types of ivy? Maybe try putting planters of ivy 1/3 of the way up, then 2/3 of the way up, then at the top? I feel like the benefits of having a cover fully filled up with ivy and maybe some LED lights mixed in would out weigh the meager cost and bad show of such a failed look. I have always wondered and could never get an answer out of any one who works there. If any one here as has answer it would be greatly appreciated
