Sequoias offer superior UV protection, aerate root structure and release harmful heat to the root zone. The rigid upper rim of the Sequoia will not flop over wasting precious water or nutrients. Sequoias stand up by themselves making filling a safe one person / one loader job. Every Sequoia has upper Velcro tie-down straps to tie down branches, hold irrigation lines or stakes in place. Sequoias twists and folds down flat to half diameter for easy storage.
