Barry Ward is the executive director of Trees For Houston. They've been giving trees away to Houstonians since 1983 – for free! All you have to do is go to their website and they'll help you get the right tree for your property and they'll even help you with planting and care. The idea is simple: native species of trees are resilient, shade-giving guardians. We discuss how they're great for water retention and absorption and how their root systems keep the ground solid and firm, even when it floods. Trees for Houston is about to open a new campus which will allow them to distribute even more trees – and they're already giving away over 20,000 a year. www.treesforhouston.org
