How To Make Garden Planters Out Of Pallets | Fast Guide

Turning old pallets into new garden planters saves money, cuts waste, and gives you custom containers that fit your space. With a few basic tools, you can turn rough timber into tidy boxes that last through many seasons.

How To Make Garden Planters Out Of Pallets Safely

Before you start cutting, you need to know which pallets suit edible crops and which ones stay away from soil and roots. Safety comes first here, for you and for anyone who eats from the planter.

Pallet Mark Or Sign	Meaning	Use For Planters?
IPPC logo + HT	Heat treated to kill pests, no chemical fumigation.	Yes, good choice for vegetable and herb planters.
MB	Treated with methyl bromide fumigant.	No, avoid for any garden use near food.
KD	Kiln dried to remove moisture.	Yes, fine for garden planters if wood is clean.
DB	Debarked only, no treatment code.	Use with care; choose only clean, unstained boards.
No stamp	Unknown origin or age.	Skip for food crops; keep only for flower planters.
Bright stains or strong smell	Possible chemical spills during transport.	Do not use in the garden.
Old green treated timber	May contain CCA or other copper and arsenic mixes.	Keep away from soil that grows food.

Look for the IPPC stamp on the side blocks of the pallet. Codes such as HT show that the pallet met heat treatment rules, which remove pests without fumigants. Pallet safety guides advise avoiding any pallet marked MB because methyl bromide treatment leaves a toxic legacy in the wood.

Extension services and wood safety groups also warn against older green treated lumber that once carried chromium, copper, and arsenic preservatives around vegetables, since these metals can move into soil and plant tissue, as shown by research on CCA treated wood. Fresh modern pallet boards that show only heat treatment or kiln drying, with no odd smell or oily staining, give you a safer base for edible beds.

Tools And Materials For Pallet Planters

Once you have safe pallet wood, gather your tools in one place. You do not need a full workshop, just a short list of hand tools and fixings.

Basic Tools

A drill or driver, a saw, and some simple layout gear cover most tasks. A cordless drill speeds up screw work, but a hand drill still works. A circular saw cuts boards down to size, though a handsaw can handle a small batch.

Add a tape measure, carpenter’s square, pencil, safety glasses, ear covers for power tools, and work gloves. These protect your hands from splinters and your eyes from flying chips as you cut pallet boards apart.

Hardware And Lining

For fixings, choose outdoor screws with a coating that resists rust. Many gardeners pick deck screws, since they hold strongly in softwood and stand up to damp soil. Galvanised nails also work, though screws make later repairs easier.

Lining protects the wood from constant contact with wet soil. A strip of weed control fabric stapled inside the planter keeps soil in place while still letting water drain. Garden advice sites suggest heavy duty woven weed membrane or hardware cloth for lining raised beds; both options allow airflow and drainage while stopping soil loss and burrowing pests.

To finish your material list, add a tin of outdoor wood stain or natural oil, potting mix or raised bed mix, and slow release organic fertiliser. These pieces help your new pallet planters last longer and give plants a strong start.

How To Make Garden Planters Out Of Pallets Step By Step

This section gives you a clear, repeatable method for How To Make Garden Planters Out Of Pallets in one standard box about 90 cm long, 40 cm wide, and 35 cm tall. You can scale the lengths up or down once you understand the pattern.

Step 1: Break Down The Pallet

Lay the pallet on a firm surface. Cut through the deck boards close to each side block with a saw, so you keep boards long and avoid wrestling with every single nail. Once the outer boards come free, flip the centre row with a pry bar and pull or cut the remaining nails.

Step 2: Cut Boards To Size

Decide on your planter length first. For this guide, cut six long side boards at 90 cm for the front and back walls. Cut six shorter boards at 40 cm for the end walls. If you want a deeper box, cut more boards at the same length and stack them higher.

Next, cut four corner posts from pallet stringers, each about 35 cm long. These posts tie the box together and lift it slightly off the ground so air can reach the base and slow rot.

Step 3: Build The Side Panels

Lay two corner posts on a flat surface and place three long side boards across them, with the outer edges flush. Leave a small gap between boards to allow air and drainage. Drive two screws through each board into each post.

Step 4: Attach The End Panels

Stand the side panels upright on their edges, posts facing in. Position one short board near the base between the front and back, then screw through the side boards into the cut end of the short board. Repeat with boards in the middle and near the top edge to close the ends.

Step 5: Add The Base

Flip the box so the open side faces down. Span the bottom with pallet boards, leaving small gaps for drainage. Screw each board into the side and end rails. For heavy soil mixes, add a centre brace strip from leftover pallet timber before you fix the base boards.

Step 6: Line And Treat The Wood

Brush loose dust from the inside, then staple weed control fabric or a similar breathable liner to the inner walls. Cut the fabric so it reaches slightly over the top edge, then fold it down and staple again for a neat rim.

On the outside, brush or roll on a coat of exterior wood stain or plant safe oil. Regular sealing slows water absorption and extends the life of softwood planters in contact with moist soil.

Step 7: Fill With Soil And Plant

Add a layer of coarse twigs or small branches at the base if your planter is deep. This saves on soil and improves drainage. Pour in a mix of topsoil and compost or bagged raised bed mix, leaving a couple of centimetres gap below the rim so water does not spill over.

Blend in slow release fertiliser pellets, then water the soil until it settles. At this stage your pallet planter is ready for herbs, salad crops, flowers, or small shrubs, depending on depth and sun levels in your garden.

Pallet Planter Design Ideas

Once you know how to build a simple pallet box, you can adjust the layout to suit balconies, patios, or larger spaces. Small changes in shape and height change how the planter works and how easy it is to care for.

Tall Pallet Planters

If you prefer to avoid bending, extend the corner posts and stack more boards to create standing height planters. A tall box with a hollow core can use logs, brush, and coarse organic matter in the bottom half, with rich soil only in the top section where roots grow.

Wall Mounted Pallet Planters

For small courtyards, a vertical garden saves floor area. Fix a pallet upright on a sturdy wall or fence with heavy duty screws through the stringers. Attach shallow boxes or pockets made from pallet boards across the front, leaving enough spacing for plants to grow.

Soil Depth, Drainage, And Plant Choices

Good pallet garden planters depend on the right match between soil depth and plant roots. Shallow boxes dry out fast but suit certain crops, while deeper planters give room for roots yet weigh far more when soaked.

Planter Depth	Suitable Plants	Notes
15–20 cm	Lettuce, radish, spinach, most herbs.	Use light mix, water often in warm months.
25–30 cm	Strawberries, dwarf beans, dwarf peas.	Good for balcony boxes and rails.
30–40 cm	Chard, beetroot, spring onions.	Balance between depth and total weight.
40–50 cm	Tomatoes, peppers, bush courgettes.	Needs sturdy frame and deep, rich soil.
50 cm+	Blueberries, small shrubs, mixed flowers.	Line base and sides well, plan for drainage.

Every pallet planter needs drainage holes or gaps. Wood at the base should never sit in a pool of water, since that speeds decay and invites root rot. Small gaps between boards, plus free draining soil mix, keep roots aerated.

If your planter sits on a deck or balcony, raise it slightly on feet or pavers so water can run clear. Check that runoff does not stain a neighbour’s wall or drip onto a walkway, and add trays or splash boards where needed.

Care, Maintenance, And Seasonal Checks

Even strong pallet planters face sun, rain, and frost year after year. Short seasonal checks keep them safe and neat without heavy repair work.

Yearly Safety Checks

If you spot soft patches in the timber, probe around them with a screwdriver. Local rot can often be stopped by cutting out one board and fitting a fresh piece in the same spot rather than scrapping the whole planter.

Refreshing The Finish

Sun and rain wear away surface coatings over time. A quick clean with a stiff brush followed by a fresh coat of exterior stain or oil once a year slows that wear. Pick a product labelled for use on raised beds or outdoor furniture.

Avoid film forming paints on the inner walls, since peeling layers can trap moisture behind them. Breathable finishes let the timber dry out between showers and extend the working life of each pallet planter.

Why Pallet Planters Are Worth The Effort

Learning How To Make Garden Planters Out Of Pallets turns a common waste item into a useful tool for home food production and flower displays. You gain custom sizes that fit narrow paths, odd corners, and sunny balcony rails without paying for new timber.

Working through one full build from pallet to planted bed also builds skill and confidence. The next time you spot a sound heat treated pallet, you will already know how many cuts and screws stand between that stack of boards and a fresh crop of herbs on your doorstep.
