The Ultimate Guide To Building A Pallet Garden

The Ultimate Guide to Building a Pallet Garden

Why a Pallet Garden?

A pallet garden turns a discarded shipping pallet into a vertical growing space. It’s cheap, sustainable, and perfect for tight spaces.

I once found a weathered oak pallet behind an old hardware store. A little cleanup, some soil, and within weeks, lettuce and thyme were spilling from the slats. It felt like magic.

A well-built pallet garden lasts years and can double or even triple your planting space.

Finding the Right Pallet

Not all pallets are safe for gardening. Some are treated with chemicals that can seep into your soil.

• Look for pallets stamped with "HT" (heat-treated). Avoid "MB" (methyl bromide) at all costs.
• Choose one with sturdy, unbroken slats. Rotten wood will collapse under the weight of soil.
• If it smells like chemicals or oil, walk away. No vegetable should grow in mystery gunk.

Prepping Your Pallet

If your pallet looks like it’s lived a hard life, scrub it clean. A stiff brush and a mix of vinegar and water work wonders.

For extra longevity, sand the rough spots. No one likes splinters while planting basil. If you want a polished look, slap on a coat of food-safe sealant.

Choosing the Perfect Plants

Not every plant plays well with a pallet. Deep-rooted veggies like carrots won’t work, but shallow growers thrive.

• Greens: Lettuce, spinach, and arugula grow fast and lush.
• Herbs: Basil, thyme, and oregano love the snug spaces.
• Strawberries: These crawl beautifully over the edges.
• Flowers: Marigolds and petunias add color and attract pollinators.

Building Your Pallet Garden

Now for the fun part—turning wood and dirt into a thriving wall of greens.

1. Position It Right

If you’re leaning it against a wall, secure it. A sudden collapse can crush plants and your will to garden.

2. Add a Backing

Staple landscape fabric or burlap across the back and bottom. This keeps soil in while allowing drainage.

3. Fill with Soil

Use a high-quality potting mix. Pallets dry out faster than garden beds, so mix in compost or coconut coir for moisture retention.

4. Plant Strategically

Start from the bottom and work your way up. Pack plants snugly, but don’t overcrowd—airflow matters.

5. Let It Settle

Keep it horizontal for a week before standing it up. This gives roots time to establish rather than spilling soil everywhere.

Maintaining Your Pallet Garden

Since pallet gardens dry out quickly, check moisture levels daily, especially in summer.

• Water with a gentle shower—harsh streams wash out soil.
• Fertilize lightly every few weeks. Too much, and plants will bolt (good for seeds, bad for salads).
• Prune lower leaves to prevent mildew from creeping in.

Common Pitfalls to Avoid

• Overloading with soil: Pallet slats aren’t beds. Too much weight, and they sag.
• Ignoring drainage: Without proper drainage, roots drown, and mold takes over.
• Placing in full shade: Unless you’re growing ferns, most plants need at least 6 hours of light.

A well-watered pallet garden can produce fresh greens year-round in mild climates.

Final Thoughts

A pallet garden transforms forgotten wood into a lush, edible vertical space. It’s simple, effective, and wildly rewarding.

There's something satisfying about growing food in a salvaged piece of shipping history. Try it once, and you’ll start eyeing every abandoned pallet with fresh possibilities.

Building a pallet garden can be a fun and rewarding DIY project. It’s a fantastic way to experiment with gardening and maximize your outdoor space. Whether you prefer a ground-level garden or a wall-mounted one, there’s no denying the appeal of these compact, efficient little patches of greenery. Happy gardening!
