Do you want to grow more plants in your garden but you’re left with no space? Or is your soil too hard to be cultivated with ease? Whatever it is, we’ve brought you the perfect solution: Raised Planter Boxes for your plants!
These boxes are extremely easy to build, you don’t need to be a professional woodworker or a craftsman to build yourself a handful of planter boxes.
You can customize them as per your liking, to go with your backyard’s design and/or house décor; and the best part is, you don’t have to settle for one placement as they are mobile, so you can move them around the house as you please, as long as the plants’ needs are met in terms of lighting, watering, etc.
So, without further ado, here is what you came for:
The 7 easy steps to build a raised planter box
Step 1: Deciding on the measurements
How big or small do you want your planter box to be?
The answer to this question depends on how many plants you want and how large or small the area you’re planning to place your planter box in is. For this guide, we are going for a 120 by 60cm box.
Step 2: Picking the material
When it comes to picking a material to work with, the options are endless. However, wood is probably your best bet as it’s extremely easy to work with and can resist the natural elements it most probably would be prone to. For a planter the size we chose earlier (120 x 60cm), a 365cm board will do.
This is basically the board you will use to cut down the sides of the planter. Note that the width should be at least 24cm.
Don’t forget to also cut out a piece that will be used as the bottom of your planter unless you want to place your box over the soil, in which case you will just add a layer of flattened cardboard pieces on the bottom, they will serve as a weed barrier.
Also, make sure to use wood that isn’t pressure-treated, as it contains chemicals that are toxic and could kill plants in the box or poison them in case you are growing vegetables.
ACQ-treated wood is a good alternative as it doesn’t contain any toxic chemicals. Alternatively, untreated wood or cedar would work just fine.
Step 3: Cut down the sides and bottom
With a measuring tape, take measures of each side, and with a pen or pencil, make sure you mark out the spots where the cut will be made.
Then, use a regular hand saw or an electric one to cut the pieces where marked. Be careful to make the cuts as straight as you can.
If you don’t have the right tools to make your cut, or simply don’t want to do it yourself, you can ask the store workers where you got your wood to do it for you, they might charge you an extra fee but some will do it for free.
Step 4: Assembling the pieces
After cutting down all the pieces you will need to build your box, you will start assembling them.
Take the two small boards (end boards) and drill three pilot holes about 1,90 cm from the end edge of the boards. These holes will ensure that the wood won’t splinter when inserting the screws into it.
Once the holes are drilled, you can start attaching the boards by using screws, choose the ones made with galvanized metal because it works great for outdoor planters, can resist the elements and is less likely to rust.
You can use a screwdriver, drill or drill bit to insert to galvanized screws and voilà – your box is starting to form!
Step 5: Adding the bottom
Once your sides are all set and secured, it’s time to add the bottom. Measure the inside length and width of your box to determine the size of the bottom board. Then, with a saw, cut your bottom board following the same measurements.
And just like you did with the sideboards, through the bottom edges of the box this time, drill some holes where to insert galvanized screws that will help secure the bottom board in place.
After that, you will need to create four to five drainage holes in the bottom of your box, these holes are important for your plant, how?
Well, they prevent any chance of it developing diseases by ensuring that the roots don’t sit in wet soil for too long, or what we call “soggy feet”. If you plan on building a larger box, then consider adding more holes.
Now, you should note that this step isn’t necessary if you’re planning to put your planter over soil or somewhere other than on a deck or a similar surface.
Step 6: Putting the final touches
Your box is almost ready, all that’s left is the finishing touches. This includes making sure the wood of your planter is protected by placing a layer of nylon or vinyl screen inside.
Now, of course, you need to cut it so that it is the same size as the bottom board of your planter. Once you lay it in, fix it in place with some small nails.
Don’t forget to drill drainage holes similar to the ones you created in your bottom board, and make sure they are lined up.
To give your box a nice finished look, give it a nice little swipe of the sander, this will smoothen the rough edges (if there are any) and vanquish any potential splinters.
Once done, add a thin layer o gravel, followed by compost or potting soil depending on which type of plants you plan on using.
Step 7: Plant your planter!
Your planter is now all set and ready to have life breathed into it! You can now add any plants, flowers, or seeds you were planning to cultivate.
Do your research beforehand to get an idea on which type of plants work best on planters, how to take care of them, how often you should water them etc.
