Keith pounded in the posts about 1 and 1/2 feet apart, with the plants centered down the middle. Then, the paneling was attached with the wire mesh in front of the posts. As the plants get taller, I'll use some thick jute twine to tie some of the larger stems to the paneling for extra support. At the end of the summer, the plants totally fill in the space and reach the height of the paneling or even higher. I like the fact that I can reach in between the "squares" to pick the tomatoes as they ripen. Totally accessible all the way around.
