How To Make Garden Planters From Pallets starts with safe pallets, solid construction, and good drainage so plants thrive.
If you have a spare pallet and a bare patio, you already hold the core of a sturdy garden planter. With a little care you can turn rough boards into neat, tidy homes for herbs, salads, or flowers that suit your space.
Planning Your Pallet Planter Project
Before you start sawing, decide where the planter will sit, what you want to grow, and how often you are willing to water. A box for trailing flowers against a wall needs different proportions from a deep container for a small shrub.
Choosing A Style And Size
Pallet wood suits several planter styles. You can keep the pallet almost intact as a vertical pocket planter, cut it down into long troughs, or strip it for boards and rebuild neat cubes or corner boxes.
| Planter Style | Best For | Typical Pallet Use |
|---|---|---|
| Vertical Pocket Planter | Herbs, strawberries, small flowers | One pallet, minimal cutting |
| Balcony Trough | Salad leaves, dwarf peas, edging flowers | One pallet cut into boards |
| Deep Box Planter | Roses, dwarf shrubs, small trees | Two pallets for extra depth |
| Corner Planter | Making use of awkward corners | Boards from one or two pallets |
| Tiered Steps | Succulents or low planting displays | Several narrow sections stacked |
| Mobile Planter On Castors | Rented spaces, roof terraces | One pallet plus base frame |
| Screen Planter | Privacy with climbers or tall grasses | Two pallets joined upright |
Selecting Safe Pallets
When you turn old pallets into garden planters, safety comes first. Not every pallet belongs near soil or food crops. Modern pallets used for international shipping are stamped with an IPPC mark that shows how the wood was treated. Look for the small wheat symbol and the code that follows it. HT means heat treated and is generally preferred for garden projects, while MB indicates fumigation with methyl bromide, which you should avoid near planting soil.
The international wood packaging standard explains that wood pallets are treated either by heat or by fumigation, and must carry a clear mark to show which method was used. This overview of pallet standards sets out the common codes you will see on blocks or stringers.
Skip pallets that smell of chemicals, look oily, or feel unusually heavy for their size. If boards are painted bright colours from industrial settings, keep them for non garden projects. When in doubt, leave a suspect pallet on the pile and look for cleaner stock.
Gloves, dust mask, and eye protection also matter when you cut or sand pallet wood, since old boards may carry splinters, grit, or traces of past use. Garden safety advice from national horticultural groups stresses steady, tidy working habits so accidents stay rare.
If you ever feel unsure about a pallet, treat it as decorative only and place a separate plastic or metal container inside your wooden shell. That way roots sit in fresh compost while the pallet still provides shape and texture on the outside.
Tools And Materials For Pallet Planters
You do not need a workshop to turn a pallet into a planter, but having the right tools makes the work smoother. Collect everything before you start so you are not hunting for drill bits with half a box assembled.
Basic Tool List
A typical pallet planter uses hand tools and simple fixings. A handsaw or circular saw, hammer, cordless drill, measuring tape, square, safety glasses, work gloves, and dust mask all earn their place. Galvanised or stainless screws last longer than nails outdoors and make repairs easier.
Extra Materials You Will Need
Alongside tools you will need weed control fabric or tough membrane, coarse gravel or broken crock for drainage, good quality peat free compost, and any paint or stain suitable for outdoor wood. If you plan to grow edibles, check the label on finishes and stick with products marked for raised beds or planters.
Pallet Planter Safety, Drainage, And Lining
Safe construction matters as much as smart planting. Pallet boards are often rough and can split if forced. Take time to sand sharp edges and fix splits before you put the planter under load. Always wear gloves and eye protection when cutting, and keep children away while you work.
Many gardeners like to line pallet planters to protect the soil from any residues on the wood and to slow down rot. A sturdy weed control fabric works well because excess water can still escape while soil stays put. For deeper boxes you can add a thin layer of gravel at the base to improve drainage, then wrap fabric up the sides and staple it to the top edge of the boards.
Positioning Drainage Holes
If you are building a trough or box with a solid base, drill drainage holes before you assemble the full frame. Space several holes across the base, then slightly enlarge the ones along the edges. Set the planter on small timber feet or bricks so water can run clear. A waterlogged pallet box rots faster and gives roots a hard time.
Step By Step: How To Make Garden Planters From Pallets
This build sequence assumes a simple rectangular box planter, which is one of the most useful designs for small gardens. You can adjust the dimensions to suit your space, but keep the basic order so the planter stays square and strong.
Step 1: Break Down The Pallet
Start by cutting the pallet into usable sections. Saw along the outer stringers so you keep board runs intact for the long sides of the planter. Then pry off remaining boards for the ends and base. Work slowly to avoid splitting. Any damaged pieces can become short braces or feet.
Step 2: Build The Side Panels
Lay out boards for the front and back panels on a flat surface. Use offcuts as vertical battens on the inside face and screw through the boards into the battens. Check with a square so the corners stay true. Repeat for the two end panels, trimming boards to match the planned width.
Step 3: Assemble The Box
Stand the panels upright and screw the ends to the inside of the front and back. Pre drilling reduces splitting near the edges. Once the frame is together, measure and cut extra boards to form the base, leaving narrow gaps between them for drainage. Screw these down onto the lower battens.
Step 4: Add Feet, Liner, And Trim
Short blocks under each corner lift the planter away from standing water and make it easier to sweep. Fix them firmly with outdoor screws. Next, line the interior with fabric, add a shallow layer of gravel, and fill with compost. If you want a cleaner look, cover the top edge with a simple trim rail made from narrow strips.
Planting Choices For Pallet Planters
Once your box is ready you can move on to planting. Shallow troughs suit herbs and salad crops, while deeper pallet planters cope with compact shrubs or perennials. Pick plants that match the light and wind on your chosen spot. Sun lovers fail in deep shade, and soft leaves scorch in strong reflected heat from walls.
Matching Pallet Planter Depth To Plants
Root depth decides how well a plant handles container life. A herb mix looks happy in a lower front row, while something woody needs far more room. Use the guide below as a starting point, and adjust for local conditions and specific varieties.
| Plant Type | Suggested Soil Depth | Notes |
|---|---|---|
| Herbs And Salad Leaves | 20–25 cm | Keep close to the kitchen door for easy picking |
| Strawberries | 25–30 cm | Ideal for pocket planters or tiered steps |
| Annual Flowers | 25–30 cm | Mix trailing and upright forms for a full look |
| Dwarf Tomatoes And Peppers | 30–35 cm | Need steady moisture and regular feeding |
| Small Shrubs | 40–45 cm | Pick varieties rated for containers |
| Climbing Plants | 35–40 cm | Fix a trellis or wires to the back of the planter |
Soil Mix And Watering Tips
Use a peat free compost blended with some garden soil or sharp sand so it holds structure. Pure compost can slump and dry out quickly. Water new plantings slowly so the whole profile is damp, then check moisture with a fingertip test.
Looking After Your Pallet Planters
Solid maintenance keeps pallet planters going from season to season. Check for early signs of rot or loose screws a few times a year. Tighten fixings, replace damaged boards, and top up compost so roots stay covered.
Wood that lives outdoors always breaks down over time. Guidance on treated timber explains that chemicals from older treated wood can leach into soil and water, so avoid sanding or burning treated offcuts. Environmental advice on treated timber waste underlines why careful disposal matters.
If you want pallet planters to last longer, brush on an outdoor wood stain rated for raised beds. Re coat every couple of years, paying attention to end grain and the base, and lift boxes onto bricks so air can move underneath.
Turning Spare Pallets Into A Cohesive Garden
Once you know How To Make Garden Planters From Pallets you can repeat the steps to build matching boxes, screens, and vertical racks. With thoughtful pallet selection and planting, rough boards turn into a small, productive planted garden corner.
