Idea: hang a trellis from molding or a board. (Trellis can come down for cleaning off or fence-painting.)
Make a basic wooden frame, staple chicken wire over it. Place the wire frame at an angle on attached legs. You then use as a cucumber trellis and plant lettuce underneath! The cucumber vines won't strangle out anything else and the lettuce grows better with partial shade!!
Trellis between raised beds avoids over-shading sun-loving veggies while allowing vines to climb beautifully.
