This DIY Planter Box with Wheels is perfect for any patio or garden area.
It works perfectly for vegetables or flowers. And rolls where ever you want it.
See our complete tutorial on how we created this below.
I'm really excited about this planter. I've had smaller rolling versions in the past, but this one is the coup de grâce to all other planters. The king daddy, y'all. It's large enough to have a big ol' tomato plant with roots that will grow nice and deep. I worked with my dad to create this one after realizing I really needed a large mobile planter. Where we are located in Texas, our summers go well into the triple digits. My tomato plants have never lasted longer than July because of the extreme heat. When we lived up in the panhandle, I had amazing tomatoes all summer long and well into September (and I miss them!). And in Texas, you just have to have homegrown tuh-mate-uhs (that's how we pronounce it down here) with your summertime meals. Or really, just one ripened tomato and a salt shaker seems to work out pretty well, too, (wink). Now that we're down in central Texas, a planter like this allows me to move my plants around the yard, depending on the heat. I can roll them right up into the shade to protect them on the scorching days. Or even get them out of a crazy hail storm when those pop up. If you live in a colder climate, these would be great to protect plants during the winter...just roll them into the garage.
Our step-by-step tutorial can help you create a DIY Planter Box with Wheels, too.
Let's get right to it! I'm showing you how we built a 2'x2'x2' planter. This can be reworked to create any size planter box you may need.
Here is what you will need to build your DIY Planter Box with Wheels:
- galvanized decking screws (you'll want galvanized since this planter will be exposed to the elements)
- wood glue
- 4 swivel casters (each should be able to support at least 100 pounds)
- 5 1x6 boards (we used treated decking boards upcycled from another project)
- 1 2x4 board (treated)
- 5 1x3 boards (this is for the trim; treated is good, but not mandatory is you finish it later)
- (not pictured) 1 additional treated 1x6 board for the floor of the planter
You will also need a compound miter saw. You could do this by hand, but it would be one heck of a job, y'all. Rent or borrow a miter saw if you can. It makes very quick work of the cuts.
Start by cutting your main boards (the 1x6s and 2x4s). They will make up the main piece. You will need twelve 24" boards and eight 22" boards if you're building the 2'x2'x2' box. We used decking boards for ours. When I told my dad about this idea, he instantly wanted to upcycle these boards he had from a deck he put in at their house (and then pulled out since he didn't love the design). He's eighty years old and building and removing decks, y'all. He can run circles around me.
You'll also need four 2x4 boards cut to 24". After cutting, we mitered one end of each 2x4, just to give them a finished look since they "peek" out of the planter on top. You definitely want 2x4s instead of the 2x2s that a lot of planters are made from...you will need the extra support for your casters. Cut two additional 22" 2x4s (you should have enough board left) that will be used to support the floor of the planter.
You'll start by assembling two of the sides with four 24" boards and two of your cut 2x4s. Use your galvanized screws to secure the boards to the 2x4. We purposefully bought skinnier screws than usual so we wouldn't have to pre-drill our holes (my dad's a genius...we didn't split a single piece of wood nor waste any time having to pre-drill). Again, create two of these boards.
Then you will connect your two sides with four 22" boards on each side. It's helpful to have a second person here to make sure the boards are lined up "tight" while the other does the screwing in.
Add those additional 22" 2x4 boards into your now connected box, at the bottom.
Screw them into the bottom boards of the box sides. These are designed to support your floor.
Add your four additional 24" boards on top of those 2x4s (you will need to notch two of the boards to fit around the 2x4 supports...we just used the miter saw to notch ours out). Your box is now complete and ready for trim.
You will cut eight 24" pieces of the 1x3 boards and eight 22" ones. We didn't miter our corners here, but if you're feeling fancy, go for it. We just attached these with simple nails. You'll only do the trim on the outsides of the box now. We'll finish the top in a bit. My dad gave me my new nail gun for my birthday. It's a blast. No pun intended.
Turn the box over and pre-drill your holes for the caster sockets.
Make sure these are drilled into the 2x4s.
Add your wood glue to each of the pre-drilled holes. Use a rubber mallet to pound the caster retainers into place (these come on the casters and just remove to be placed into the space they're needed).
Then screw the casters into their retainers by hand (they just drop in and twist to tighten).
Your box is really heavy now, but go ahead and turn it right side up to finish the top trim. This is the only part we mitered. We cut four more 1x3 pieces to form a square to sit on top of the box and cover all of the layers of wood. Just nail these into place once cut. I did give them a good sanding once in place.
Ta-da! I then finished it off with an outdoor stain and seal product.
Since we used both new and upcycled wood pieces, it gave it a more uniform look.
I did not stain the inside since the wood was already treated and ready for planting.
All stained and ready for planting. We used a much larger tomato plant than usual...it's actually quite late in the planting season for us down here. We thought a larger plant might help us catch up. We also used Miracle-Gro® Potting Mix and a sturdy tomato cage.
We grabbed our Miracle-Gro® Potting Mix at the local Walmart. We used the larger two cubic foot bags that are now located in the outside garden center. Or click here to grab a bag online.
This Miracle-Gro® Potting Mix will feed my tomato plant for up to 6 months. It works the same on flowering plants and other veggies, too. We've used this potting mix for years and it works so well. Be prepared to watch your plants grow BIG...
Come on, tomatoes! We've got our salt shakers ready for ya.
Already spotted a couple of blooms.
My husband added the butterfly. It moves with the wind...hoping it keeps the darn grackels away from my plant by scaring them. They eat half of every crop of tomatoes I've ever planted.
Do you have a spot where a DIY planter box with wheels would work for you?
