What is Benderboard used for?
Bender board is a 1/4-inch composite or redwood product that is used to edge lawns and gardens. This product is particularly good at conforming to tight corners, and this contributes to its popularity which sometimes makes it difficult to find in stores. Bender board is sold in long rolls which also means fewer joints.
