Tim Bevan, Estate Curator, talks about trialling a new way to control flood damage of river banks at The National Botanic Garden of Wales. They are using plastic socks filled with household compost and planting trees such as willow into these. These trees should, it is hoped, bind the soil together, so making the river banks more settled. The project site is in Pont Felin Gat, a wooded valley 10 minutes walk from the Great Glasshouse. The project is being funded by WRAP..
