I just pounded the posts in about 18". I will attach extensions to the tops when needed. They are 2' apart and 1 1/2' away from the wall. They back row of plants are between the posts, 2' apart. As an after thought I added the front 7 plants in front of the posts. They are mostly determinates or semi-deterinates so I hope the back row being all indeterminates will get a lot taller than them. A soaker hose is under the black mulch.
