Tips to Build Your Own Planter Box 

If you live in Toronto, I am sure you must have come across some awesome structures built with wooden blocks called EZblocks (formerly GripBlock). I’ve been to outdoor markets, skating rinks and restaurant patios in Toronto where I’ve seen some amazing uses for EZblocks. I was so curious about these blocks that I ordered some to play around with. 


EZblocks - Different Application Solutions

EZblocks are just like children’s building blocks. They offer fast, strong, easy-to-assemble building solutions which makes them great for a wide range of applications like patios, markets, benches, mazes and ice rinks, sheds, and more.


After understanding how these blocks work, I came up with a project idea: DIY garden planter boxes. EZblocks are literally like the building blocks my kids play with. You can build anything you want today, and change it up tomorrow. This is the best way to build a planter box or a raised planter box for your backyard.


Why EZblocks for your planter box

Advantages of using EZblocks for your planter box DIY project:

  • No hassle of cutting wood pieces
  • You don’t need power tools or screws
  • Your EZblocks planter box will stand up to outdoor conditions without any extra steps from you
  • You can paint it, stain it easily
  • You can customize your planter box easily, so it can be exactly what you want
  • If you move, or change your landscaping, you can easily take this apart and build a new structure. You can even use this to build your own DIY yard games or patio furniture!
  • The metal velcro-like technology on the EZblocks means a secure, solid structure
  • The planter box can be as small or as big as you want. The size and shape are totally up to you!



Materials To Build a DIY Planter Box

Building a DIY planter box or a raised garden bed with EZblocks is easy. You don’t need to cut any wood pieces, and you don’t need any power tools. This is super simple!

Similar to CLT and concrete, EZblocks is a single block that can be placed precisely like a children’s building brick. And the great thing is they come in different sizes too.


Here are some things that are important to consider before you start your build:

  1. Figure out the size of the planter box
  2. Make a rough drawing of the DIY planter box so you can visualize it
  3. Buy a fine mesh screen or landscape fabric. This will be used to line the bottom of your planter box. 
  4. Select your lumber. In this case, we are using EZblocks, which means you don’t need to worry about your materials lasting under outdoor conditions.  
  5. Determine how many blocks you’ll need to complete your build

Assembling Your Planter Box

Building a planter box is an awesome way to add colour and greenery around your deck, patio or garden. With EZblocks, you can do this DIY project in a weekend. And what I love about these blocks is that they’re made out of recycled wood with no glues or fasteners. So they’re better for the environment too!

Step-By-Step Installation Guide

Your DIY planter box or raised garden bed needs to be sturdy enough to hold plants and moist soil. It’s important that the blocks are properly secured. The good thing is that with EZblocks, the metal velcro takes care of that. No need to drill holes or measure precisely. 

Here’s how to build the planter box:

  1. First, make sure you have a flat, level surface for building your structure
  2. Line your EZblocks up to build the first row
  3. Add one piece of rebar into the center of your first row
  4. Place the next layer of blocks on top, but make sure it’s offset from the layer below —pretend you’re laying down bricks. You can use a rubber mallet to make sure the blocks are secure in place
  5. Keep adding layers remembering to offset it from the layer below until you get the desired height
  6. Add two pieces of rebar into the center of your top row of EZblocks
  7. Insert your threaded hooks into your EZblocks from the top, hook to the bottom piece of rebar
  8. Attach a clamping bracket and a nut to the top of your threaded hook and tighten it down
  9. Place top caps over all the block openings and secure them using screws
  10. Close all end openings with end plugs. Use a rubber mallet to tap them into place


That’s it. Now you can paint it, stain it, or leave it plain and functional —the only limit is your imagination.



Sherry’s Tip: Add some landscaping lights and spot lights to highlight your planter box and set a nice ambiance in your backyard!
