Recommend a Nontoxic Waterproof Wood Sealer For Outdoor Windowboxes?
Q: Can you recommend a nontoxic waterproof wood sealer for my outdoor window boxes? I’m building and planting my own outdoor window boxes this year, and I’m having a hard time finding a nontoxic waterproof wood sealer that won’t poison my plants or the environment, and that doesn’t need to be reapplied every year. Any advice?

While you’re right that you still have to search hard among conventional wood sealers to find a non toxic finish that’s a healthy alternative, that is changing.
There’s no need to subject yourself and others to toxic chemicals, or to poison your plants as they begin to grow.
Reviews often point out that these products are not as durable and long-lasting as traditional sealers, and that they are hard to apply and costly, but with only planter boxes to cover, rather than a deck or fence, any of these products should serve you well.
