We are in Austin, TX, and thinking about planting bamboo along our back fence as a privacy screen. Any tips for us? We know it spreads rapidly, and we are planning on lining the trench with something, although we have been told that even with lining it's a bad idea. We were looking for plastic sheeting. Any ideas on liners? Any horror stories or success stories you'd like to share? thanks in advance. Also I am new to this community but we love our garden here in TX!
