Setting Stones in Garden Beds
It's all in the drainage
What different types of bricks and stones can be used to line outdoor planting beds, and what materials and steps are involved in the project?

Roger Cook replies: You can use any stone for edging beds, but brick, cobbles, bluestone, and granite are the traditional choices. The key is to excavate below them and install gravel for drainage. I use cement to hold them in place, but for a more rustic look you can set them in gravel and let them move a little.
