Build a DIY Herb Garden Planter from Reclaimed Wood: A Weekend Project Anyone Can Do

There’s something deeply satisfying about cooking with herbs you grew yourself. The moment you pinch a few leaves of fresh basil or snip a sprig of rosemary right before dinner, you realize how much better everything tastes when it came from your own hands. But buying a good-looking planter can be surprisingly expensive, and plastic versions rarely hold up well outdoors or look particularly inviting in a kitchen window. That’s where this weekend project comes in.

This week’s project is a DIY herb garden planter built from reclaimed wood. It’s beginner-friendly, costs very little if you have access to old pallet wood or salvaged lumber, and produces a genuinely beautiful result that looks like it came from a boutique garden shop. You can size it to fit a windowsill, a balcony railing, a kitchen counter, or a backyard garden bed. Best of all, the whole thing can be done in a single weekend, even if you’ve never picked up a saw before.

Let’s walk through everything: the materials, the tools, the steps, some common mistakes to avoid, and a few creative variations to make it your own.

Why Reclaimed Wood Is the Right Choice for This Project

Before we get into the how-to, it’s worth talking about why reclaimed wood makes such an excellent choice for a planter — beyond the obvious appeal of giving old material a second life.

First, reclaimed wood tends to be drier and more stable than fresh-cut lumber. Wood that has already been through years of expansion, contraction, heat, and humidity is far less likely to warp or crack when it gets wet. A planter that holds soil and water is going to deal with plenty of moisture, so starting with wood that’s already weathered makes a real difference in how long your project lasts.

Second, reclaimed wood has character. The grain is often richer, the color more complex, and the surface more textured than something you’d pull off a big-box store shelf. Old pallet wood, fence boards, barn siding, and shipping crate planks all have a personality that new lumber simply doesn’t replicate, no matter how carefully you stain it.

Third, it’s almost free. Pallets are given away constantly by hardware stores, garden centers, and grocery stores. Old fence boards are easy to find on local buy-nothing groups or from neighbors replacing their fencing. A quick search on Craigslist or Facebook Marketplace will usually turn up more wood than you need.

The one thing to watch for with pallet wood specifically is the stamp on the side. Look for pallets marked “HT” (heat treated) rather than “MB” (methyl bromide treated). Heat-treated pallets are safe for growing food. Methyl bromide-treated ones were chemically treated with a pesticide and should not be used in projects where plants, especially edible ones, will be growing nearby.

What You’ll Need

You don’t need a workshop full of professional equipment to complete this project. Here’s a practical list of what to gather before you start.

Materials: Reclaimed wood planks (aim for pieces roughly 1 inch thick and 4 to 6 inches wide), exterior wood screws in 1.5-inch and 2-inch lengths, exterior wood glue, landscape fabric or burlap, a staple gun with staples, sandpaper in 80-grit and 120-grit, and an outdoor wood sealant or food-safe beeswax finish if you plan to use the planter for edible herbs indoors.

Tools: A circular saw or miter saw (a handsaw works fine too, it just takes a little longer), a power drill with a Phillips head bit and a drill bit for pilot holes, a tape measure, a pencil, a square or ruler, clamps if you have them, and safety glasses and gloves.

Optional extras: Wood stain, chalk paint, iron brackets for a wall-mounted version, rope handles, or small metal labels for identifying your herbs.

Choosing Your Design and Dimensions

One of the best things about building your own planter is that you can make it exactly the size you need. Before you start cutting, decide where the planter will live and measure that space.

For a windowsill planter, a finished size of about 24 inches long, 6 inches wide, and 6 inches deep works well and can comfortably hold three to four individual herb plants. For a counter or table planter, you might go a little wider — 8 inches — to give roots a bit more room. For an outdoor raised bed-style planter, you can scale up dramatically, going 48 inches long, 12 inches wide, and 10 inches deep.

The design we’re building here is a simple rectangular box: four sides and a bottom, with small drainage holes drilled through the base. No fancy joinery, no complicated angles. The box is held together with glue and screws, and it’s stronger than it looks once the wood has been properly fastened and the sealant has cured.

For a standard 24-by-6-by-6-inch planter, you’ll need two side pieces at 24 inches long, two end pieces at 4.5 inches wide (accounting for the thickness of the side boards), and a bottom piece at 24 inches by 6 inches.

Step One: Prepare Your Reclaimed Wood

Start by inspecting your wood for nails, screws, or staples. Use a pry bar or needle-nose pliers to remove any hardware. Even small tacks can damage your saw blade or leave rust stains in the finished piece, so take your time here.

Once the wood is clean, give it a rough sand with 80-grit sandpaper. You’re not trying to make it silky smooth — you actually want to preserve some of the texture and character of the old wood. What you’re doing is knocking down any splinters, removing loose paint or grime, and opening up the surface a little so the sealant will penetrate properly. Follow up with 120-grit if you want a slightly smoother finish.

If your planks are uneven in width, try to sort them so that your sides and bottom are as consistent as possible. A small variation in thickness is fine and actually adds to the handmade look. But if you have one plank that’s dramatically thinner than the others, save it for a different part of the project — the drainage bottom, for example, where visual consistency matters less.

Step Two: Cut Your Pieces

Measure twice, cut once — that cliché is genuinely useful advice. Use your tape measure and pencil to mark all your cuts before you fire up the saw. Lay the marks out clearly and use a square to ensure your lines are perpendicular to the edge of the board.

When cutting, always support both ends of the board so that neither side drops as you finish the cut, which can cause the wood to splinter or bind against the blade. Cut slowly and let the saw do the work rather than pushing through.

Once all your pieces are cut, do a dry assembly — hold or clamp them together without glue to check that everything fits before you commit. Minor gaps at joints are fine; you can fill those with exterior wood filler after assembly or simply embrace them as part of the rustic look.

Step Three: Assemble the Box

Apply a thin, even bead of exterior wood glue along the edge of one of your end pieces and press it against the inside face of one long side piece. Clamp if you can, or hold firmly for about 60 seconds while the initial bond sets. Then drill pilot holes — small guide holes just slightly narrower than your screws — through the long side board and into the end piece. Pilot holes prevent the wood from splitting, especially in older reclaimed lumber that may be a little dry and brittle.

Drive two 2-inch screws through the pilot holes to lock the joint together. Repeat for the other three corners. Then attach the bottom piece: run a bead of glue along the bottom edge of all four walls, set the bottom panel in place, drill pilot holes, and use 1.5-inch screws around the perimeter, spacing them every 4 to 5 inches.

Now flip the box over and drill four to six drainage holes through the bottom using a 3/8-inch or 1/2-inch drill bit. These are critical. Without drainage, your herb roots will sit in standing water, which causes root rot and kills plants quickly. Make sure the holes are spaced so that water can escape freely from all sections of the planter.

Step Four: Line the Interior

Cut a piece of landscape fabric or burlap to fit the interior of the box, pressing it into the corners and up the sides by about an inch. Staple it in place along the top edges. This liner serves two purposes: it keeps the soil from washing out through the drainage holes, and it creates a barrier between the moist soil and the wood, which meaningfully extends the life of your planter.

If you can’t find landscape fabric, burlap coffee sacks work beautifully and are often available for free from local cafes. Window screen material also works well and is especially good at keeping out pests.

Step Five: Seal and Finish the Outside

The outside of the planter deserves a finish that will protect it from moisture, sun, and the inevitable splashes of watering. For an outdoor planter, a good exterior sealant or decking oil is your best bet. Apply it with a brush, working it into the grain, and allow it to dry fully before adding soil.

For an indoor planter, or if you’re growing herbs you’ll eat, consider a food-safe beeswax finish instead. Simply melt beeswax with a little linseed oil, brush it on warm, and buff it in. It won’t last as long as a synthetic sealant but it’s completely non-toxic and gives the wood a beautiful, slightly warm sheen.

If you want to add color, chalk paint goes on beautifully over raw reclaimed wood and doesn’t require any priming. Sage green, slate blue, and terracotta are all popular choices for herb planters and look wonderful against the natural herbs growing inside. You can also whitewash the wood by diluting white paint to about 50% with water and applying it lightly, letting the grain show through.

Step Six: Plant Your Herbs

Once the finish has dried completely — give it at least 24 hours, ideally 48 — you’re ready to plant. Fill the lined box with a good-quality potting mix, ideally one formulated for herbs or vegetables. Avoid using straight garden soil, which can compact in containers and restrict root growth.

Herbs that do well together in a shared planter include basil, parsley, and chives; or rosemary, thyme, and oregano. Try to group herbs with similar watering needs. Rosemary and thyme, for example, prefer drier conditions, while basil and mint like consistent moisture. If you mix a drought-lover with a water-lover in the same box, one of them will always be unhappy.

Plant at the same depth the herbs were growing in their nursery pots, press the soil gently around the roots, and water thoroughly until it drains from the bottom holes.

Creative Variations Worth Trying

Once you’ve built one, it’s hard to stop. A few variations that have become popular with people who’ve done this project:

A wall-mounted version is easy to create by adding a simple wooden ledge bracket on the back, or a pair of iron pipe brackets screwed into the side boards. Mounted at window height, a row of herb planters on a kitchen wall looks stunning and frees up counter space entirely.

A tiered planter is another option — essentially two or three boxes connected at different heights by a simple wooden frame. The bottom tier can hold larger plants like rosemary or lemon verbena while the upper tiers hold compact herbs like thyme and basil.

Adding a small chalkboard label to the front of each planter compartment is a practical and charming touch. You can buy small chalkboard panels, or simply paint a rectangle with chalkboard paint directly on the front face of the box.

Finally, if you have children who want to get involved, this is an excellent project for them. Let them sand, help hold pieces while you fasten them, and paint the outside. A personalized herb garden planter that a child helped build is one they’ll actually be interested in maintaining, which is a rare and valuable thing.

A Few Things That Go Wrong (and How to Avoid Them)

The most common mistake is skipping the pilot holes. Reclaimed wood is often drier and more prone to splitting than fresh lumber, and driving a screw directly in without a pilot hole will frequently cause a crack right through the piece you’ve worked hardest on. It takes an extra 30 seconds per joint — always worth it.

The second most common mistake is underestimating the weight of a filled planter. Soil is heavy, and a 24-inch planter full of moist potting mix can weigh 20 pounds or more. If you’re mounting this to a wall, make sure your anchors are going into studs, not just drywall. If it’s sitting on a surface, make sure that surface can handle the weight.

Finally, don’t rush the drying time on your finish. It can be tempting to plant immediately — the planter looks done, you have herbs waiting on the counter, and the sealant feels dry to the touch. But if the sealant hasn’t fully cured, contact with moist soil can cause it to peel or discolor. Patience here pays off in longevity.

Why This Project Is Worth Your Weekend

In a couple of days, using materials that might otherwise end up in a landfill, you can have something genuinely beautiful and functional in your home or garden. The skills you build — measuring, cutting, drilling, assembling, finishing — translate directly to dozens of other projects. And the herbs you grow will find their way into your cooking week after week, repaying the investment in time and materials many times over.

There’s also something quietly meaningful about making things by hand. We spend so much time interacting with screens and systems that don’t leave anything tangible behind. A wooden planter you built yourself, sitting on your windowsill and growing something you’ll eat, is a small but real counterweight to all of that. It’s yours in a way that few things are anymore.

Give this one a try this weekend. You’ll be glad you did.
