The last two beds are made from 2" X 8" boards. These are quick and easy to set up, but will need to be replaced in time due to rot. In wet climates these may only last a couple of years. Here in Northwest Arkansas they should give 4-5 years of service before needing replacement. Treated wood, waterseals, or paint can be used to prolong the life of the frame. Out of concern for chemical leaching, these beds use untreated wood.
Tomatoes, zucchini, green beans, peppers, and spaghetti squash in these wood framed beds.
