About 3 years ago, I built eight ( 8 ) raised beds all out of cedar for the neighbor. She started out growing vegetables and a few flowers. Now the boxes are almost all flowers.
Today, I'm finishing up ( 6 ) six new raised boxes for her. To save on cost, she decided that treated boxes capped with cedar would be fine. The cedar cap will blend the new, somewhat, with the old.
Boxes are 4ft wide and 10ft long. Personally, I think they are to wide and treated wood is wrong.
The customer is always right.
