Related: About this forumQuestion regarding choice of planter.
I opted for an aluminum raised planter because my aluminum tools hold up better in Florida than galvanized steel, and then I realized I made one critical mistake. I plan to put this near the pool and chlorine and aluminum don't play nice together. The answer is a sealer. What sealer would you all recommend that is safe to use for edible gardening purposes?
Thanks in advance.
Oh, I prefer a clear sealer.

Avoid sappy pines as those emit acids-? that prohibit growth of other plants so go with something else. Or, if you have to use pine, use straw inside of that. Maybe straw could work?

(96,237 posts)I meant to line the box with it but termites being a thing there, maybe straw so that there is less problem with soil contact with the metal. That's what I was thinking about,
I used straw for all kinds of utilitarian purposes in the garden last year and I was hppy with the results. It works as insulation and coverage for weed control, cover seedbeds for warmth while germinating, that sort of thing.
You'll figure it out.
