That thing got huge and we tore it off last fall to make wreaths out of the vines and now it can grow back... but I am debating yet on that. It is a nusiance to clean, ubt will put a little shade on the GH.. so hmm to let the vine come back or not, that is the question..
Both the algea thing and the vine remains I am hoping will powerwash off. I think I will just use some dawn dishsoap when I give her a blasting and then follow it by a bleach rinse. That should not hurt!
