Exterior Use Wood Preservitve

I’d say that you’d have to line the interior with something to keep the soil and moisture away from the pine. I don’t think it would last long without that. And then you’d have to use some type of weather proofing on the outside. Lots of it. At least once a year.

Consider pine as disposable. Redwood or eastern cedar will last longer. White oak will last for a while as long as the planter is cleaned and any termite infestation killed annually. Locust, (hard to find and harder to work with) would last longest.

Rot is part of the problem and bugs are the worst problem.
