Photo of bamboo grape trellis after 8 or 9 years. Used golden bamboo culms during construction. Used a small blow torch to harden the wax on the culms. Wax broke down in 2 or 3 years. Treated culms in soil and they held up for several years prior to rotting out. The major problem was wind. As leaves filled in, a sail effect developed so there was a major push/pull on the lower struts.
Latest photo after overhaul.
Had to add struts to handle the effect of wind.
Cut off culms that rotted out and reinserted then in larger culms that were deeply dug into the soil.
The old trellis culms have not been retreated. RGDS
