This is my first time coming across this situation. So I'm reaching out to my landscaping brothers/sisters out there. The attached images will show what I'm up against. Need to create a bed of ornamental grasses in the planter. Here's my delimna... If pack sand/soil in the planter, here in New Orleans, termites will have a feast on the fence over time. Althought the fence is painted, moisture from the soil/rain will break this down over time. 1. How do I protect the fence? (Plastic sheeting etc....) 2. Should I build a wall inside of the planter close to the fence? Hmmm... Also you see there are shut off valves for the plumbing to the pool. I can't cover them up. I need a work around. Please provide any suggestions. The planter dimensions are 30' (L) x 3'8" (W) x 2'2" (D). I appreciate any feedback. Thank you for your time.
