Raised garden bed questions
We are making a large raised planter for vegetable garden. We built the planter with untreated fir wood. We want to keep this garden as organic as possible, couple of questions regarding this.
1. We want to stain the exterior to protect the wood from the rain/water damage. Is it OK to stain the interior?
2. Our planter bottom is built such a way that water drains nicely from the bottom. We want to use an interior liner on the sides to protect wood from the moisture. What is the best liner to use to prevent chemicals? Is rubberized sealer a good choice?
Any advice is appreciated.
