Q:     My husband is concerned about building the frames out of wood - he doesn't want to be replacing them due to termite damage. Do you have any suggestions for some other building material that might be more permanent ?

A:     I wouldn't use treated lumber if you're going to grow vegetables. Recycled plastic wood is readily available and vinyl fence material makes a great SQUARE FOOT box. Some people use bricks and cement blocks. Those that get FREE scrap lumber from construction sites (ask first) don't mind changing frames every 4 or 5 years.  Good luck !
