I recommend at the very least coating your lumber in linseed oil or beeswax to preserve them for the long haul. Some gardeners use lining between the interior of their raised bed and soil to protect the wood. Even with the lining, you'll get seepage of water that will penetrate that wood and linger.

For sealing a raised bed, we recommend using a thin-layer stain, as this penetrates deep into the wood and therefore also protects it from the inside. Our expert Sari opted for a stain for her project. Both paints and woodstains protect your raised bed from the weather and therefore increase the durability of the wood.

Here's how to paint our galvanized metal garden beds: You will need to go to a store that sells METAL primers and paints. Apply the metal primer as directed, covering the entire surface of the metal. It's best to start at the top and work down. Let the primer dry according to the directions.

As a final reminder, avoid lining your garden beds with plastic. Doing so prevents drainage and could drown your plants' roots with too much water. If you have a weed and pest problem, consider installing a combination of metal mesh and fabric or hardware cloth and cardboard to address both issues simultaneously.

Sealing wood garden beds can help extend their lifespan many years beyond unsealed wood. Applying a sealer will protect the wood from moisture intrusion, mold, and decay.

Do I need pressure-treated wood for raised garden beds? ›

Even though the new pressure-treated woods are considered safe, Wolmanized Outdoor, according to its Web site, does not recommend using pressure-treated wood where the preservatives may become a component of food. Its recommendation is to use an impervious liner between the wood and the soil.

3. Sand: A layer of sand can help improve drainage and prevent soil compaction. However, it's important to use the right type of sand. Avoid using beach sand, as it can contain salt and other minerals that can harm your plants.

Non-toxic paint on the outside of your raised beds will not affect the plants growing inside the bed. Some examples of non-toxic paint include milk paint (made from natural ingredients like milk protein, organic pigment, and lime) and VOC-free latex paints (VOC stands for volatile organic compounds).

The Type of Wood Used

Cedar, redwood, cypress, and hemlock are all types of wood that don't decay or rot quickly, and they can be expected to last anywhere from 10 to 20 years. Check which of these durable boards you can find locally sourced. My preference is always untreated cedar.

It's best to use a satin or semi-gloss finish for a long lasting effect. Paint them as you would a wood painter, using an appropriate-sized paintbrush. Let the paint dry completely. Lastly, seal the planter before refilling with soil and plants or before decorating (See Step 5).
