Over the past year I've come across scores of diy pallet projects, some of them intriguing and others not quite there yet but still having potential. One that I see time and again is the idea of using a single wooden pallet as a strawberry planter. Filled with soil and with plants inserted in the gaps they're usually leaned up against a wall but sometimes bolted on to keep from tumbling over. It's a clever idea but I've steered away from trying it myself because I suspect that they'll require constant watering and erosion control and also because I'm not convinced that they'll work long term. Almost every image I've found of pallet planters look to be newly planted rather than a tried and tested design.
Still I was interested in the idea and with the gift of eight pristine wooden pallets, I started scouring the internet looking for alternative tutorials. Ones that offered increased stability, more soil capacity and better aesthetics. Eventually, after finding nothing that really jumped out at me, I came to the conclusion that I'd have to come up with my own design. After thinking about the process for this post I'm quite sure that anyone who is comfortable using a hammer and hand-saw could complete this project too. Though I'll be honest and say it's much easier if you have a jigsaw and a few other extra tools.
For this project you will need the following materials:
- A suitable pallet as described in the next two steps
- A hand-saw or jigsaw
- Electric drill or hammer
- Two sizes of screws and nails - approx. lengths 4 cm (1-1/2") and 8cm (3")
- Heavy duty chisel/wedge and iron mallet
- Non-toxic paint and paintbrush
Step 1: Choosing Your Pallet
First of all, choosing pallets for diy projects involves a bit of know-how. You need pallets that are in good condition, without rot, and which have not been treated with chemical insecticides. Most people are probably not aware of this but pallets that cross international borders must be either heat treated or sprayed to stop the spread of foreign pests. Whether you think this is a good idea or not, you certainly do not want pesticide-soaked furniture or objects in your garden let alone your home. Not only can it kill off insects that eat your crops but it can indiscriminately kill all the beneficial insects too. There's also the possibility of your plants absorbing these chemicals into their tissues and into your tasty strawberries!
To help you find the right type of pallet for your project I've put together a diagram of what to look for when you spot one. By international law, a pallet must be stamped twice with certain information which includes whether it's been sprayed. Keep clear of any pallets that have been printed with the letters MB.
Step 2: Pallet Specs
For this project you will also need to look for a pallet that has six or nine planks making up its main surface. The reason for this is that the first major step will be in slicing the pallet up into three equal sized pieces (both six and nine are divisable by three). If there's such a thing as a pallet with twelve planks then all the better because that means you can build an even larger planter.
Step 3: Cut the pallet into three equal pieces
The easiest way to do this is to cut lay the pallet so that the long planks are in parallel with your own position. If your pallet has nine planks, like mine did, then count over three planks and then saw the wood between the third and fourth planks. Saw right in the middle, to keep things easy and to ensure that all of your proportions remain correct. Continue another three planks and cut again. Remember that you'll have to saw in the exact places on both the front and back of the pallet.
Step 4: Trim and remove excess wood pieces
You'll have three pieces of pallet now, all of the same height and width. Two of the pallets will be formed from the top and bottom and will have chunky blocks securely fixed to them between one of three planks on the front side and the single one left on on the other. You'll want to trim off the excess wood jutting up from each one of these wooden blocks. Please refer to images for step one and two. Though I chose not to do it in this project, you could also remove that single plank on the back side. If you do this then you could have a deeper planter - it's up to you.
The piece that made up the centre part of the pallet also has thick wooden blocks sandwiched between its front side and stubby planks on the other. Pull these blocks and stubby planks off but keep them in reserve - you'll need them to complete the project. If there are nails sticking up after removing these pieces then either hammer them flat or remove them completely.
Step 5: Construction begins
Fix the two end pieces to the middle part of the pallet. Screw in from the other side of the middle (bottom) piece.
The two end pieces will be the sides of your planter and the middle piece is the bottom. Though the image shows the structure right way up, it's actually easier to flip it over in order to fix the bottom piece to the sides. You'll want to screw or nail the bottom piece into the wooden blocks still attached to the side pieces.
Step 6: Preparing wood for the feet and short sides
You should have three to four of these pieces that were removed from the centre piece of the pallet. Separate them into individual blocks and planks.
This is easier said than done if you don't have the right tools. Since pallet wood that has been heat treated can be brittle if you try to pull the plank off with the tongs of a hammer. If you have a heavy duty chisel then I recommend that you use it to separate the block and the plank and sever the nails in two. If you're planning on doing any more pallet projects you could really save yourself a lot of tears and invest in one along with an iron mallet down at your local hardware store. If any of your pieces have bits of nails sticking out then try to hammer them flat.
Step 7: Use planks to create the sides and the blocks for feet
If you've followed the directions in step 1 and sawed in the middle between the long planks, then the little planks leftover from step four should all be approximately the same length. They will also be the same width you need to create the shorter sides of your planter. If your original pallet was the same size as mine then you'll have four of these planks to make up two pieces for each side. The bottom planks for each of the shorter sides can be created by re-using the bits of wood you cut off the side pieces in step two. For a more pleasing and symmetrical effect, line the small side planks up with the planks along the front and back pieces.
Attaching the wooden blocks as feet can be a bit tricky and in the end I drove very long screws in sideways to attach them to the bottom of the planter. Putting feet on the piece will help with drainage and slow down the process of the bottom rotting. I think they also make the planter look nicer.
I can foresee some people finding pallets of slightly different sizes to mine and being left with less small planks and blocks in this step. In fact it's more likely that you'll end up with three of each rather than four, especially if you're using a smaller pallet. In this case you'll be cobbling together more scraps to make and additional side piece and having to find a fourth block to use as the last foot. In this case I'd look at removing one of the inner blocks from the side pieces to use.
Step 8: Project Completed!
Well almost :) Turn your planter right way up and have a look at it. Does it feel sturdy? Are the feet wobbly? Are there extra bits of wood sticking up that you could trim back? Once you feel the planter is complete then either plant it up as is or use a non-toxic outdoor wood paint to paint the exterior. Being wood, this piece will eventually rot down but some tlc now can help extend its life.
