Waterproofing a Garden Box - Knowledgebase Question

Question by Renee92182

I have wooden garden box 9ft x 9ft. We used untreated wood and lined the interior of the box with plastic wrap to protect it from moisture and rotting. Is it safe to use waterproofer/stain on the exterior of the box? Is it likely that this would leak into the soil and affect the vegetables that we plant?

A water based waterproofing stain should not penetrate the wood deep enough to leach into the soil. Of more concern is the plastic liner. You will need to either leave the bottom unlined or punch lots and lots of holes in it to allow excess moisture to escape. Otherwise water will pool on the bottom, stagnate, and keep the soil too soggy. Best wishes with your new planter!
