How can I convert a wooden crate into an herb garden?

It would be best to get a plastic or metal liner for it. Moist soil against the wood will cause it to deteriorate and fall apart quickly. On out side use spar varnish if want natural or Prime and use exterior paint. You'll need to sand between coats on both.

Use exterior paint and pick a bold color that will help bring color to your outdoor space! I bet this will be great!

I love the idea of repainting it! Don't forget to drill out drainage holes for when you water.

Thank you so much. SO HELPFUL!!!

I would flip the crate so the opening is at the top. Line the crate with a plastic trash bag with a few holes in the bottom of the bag. The crate looks as if there would be plenty of drainage in it. Fill the bottom third of the bag with empty plastic soda and water bottles. Fill in the spaces around the bottles with small rocks. Add a one foot layer of mulch, coconut hair, moss or less than that if you use artificial turf/grass. Fill the rest of the crate almost to the top with planting soil, for seeding or starter plants. Then place your herb starters into the mix, keeping strong scented herbs like onions on the opposite side from delicately scented herbs like chocolate mint.

Water the plants when needed, or when the soil is dry three inches down. The crate will more than likely rot after one or two years outside, even if you paint and seal it, but it might last longer, but per year, that’s not a bad deal, even if you add more potting soil and a little fertilizer each year. Enjoy! Jewell

I would line it with a plastic bin as close to the size of the box as possible. Before adding the bin, drill holes in the bottom of both the bin and box to allow for drainage and place a layer of smallish rocks (not smaller than the holes, though) between the box and bin. This will also allow you to use more rocks if necessary to bring the bin to the top level of the box. I would also seal it with outdoor stain inside and out first.
