How To Make A Planter Box


Planting is a rewarding and therapeutic activity. If you want to start a garden but don’t have the backyard space, no worries! You can start your own garden on a patio or balcony with this simple planter box tutorial. What’s more, I’ll show you how to line the planter box so it fits perfectly in your space.

# Writing Style Guide

Step 1

Measure your patio. You’ll need to decide on the size of your planter box and how deep it will be.

Buy wood and lining. If you have a local hardware store that sells discounted lumber, you can buy enough wood for your planter box there at a low price—but if not, online retailers like Home Depot and Lowe’s are good places to look for deals on all types of materials (including the lining).

Buy nails, glue and soil. These are some other necessary supplies you’ll want on hand before starting any construction work on your planter box: nails; glue; soil; plants! And tools like saws, hammers or screwdrivers if needed (buy these early so they don’t get lost in storage).

Step 2

Once you’ve got your measurements, it’s time to start building. You’ll need:

  • A level
  • A tape measurer
  • Pencil and paper (to sketch out your plan)
  • Saw, drill and screwdriver (or hammer)

The process of building a planter box isn’t complicated, but there are a few things to keep in mind as you build it. First, always use the square or angle attachment on your saw when cutting wood—it’ll give you cleaner cuts than using just a regular blade will. Next, hold onto those corners! Builders often forget that they need to secure their boards firmly together at the corners with screws or nails. Otherwise they can sag over time as water seeps into the wood from rain and snow runoff. Finally, if possible try not to use pressure-treated lumber—it contains toxic chemicals that may leach into the soil over time (but if necessary do so after lining with plastic sheeting).

Step 3

The next step is to cut the side pieces. For this, you will need your tape measure and a pencil.

  • Measure the length of your box and mark it on your 1×6 board.
  • From there, measure the width of your box and mark it on the same piece of wood.
  • Then take two more pieces of wood and place them at 90 degrees from each other (so they form a V shape).
  • Use a circular saw or table saw to cut out this shape from each piece so that you end up with 4 identical sides for your planter box!

Step 4

You’re almost done!


  • Use a level to make sure the frame is even.
  • Use a drill to make holes for the screws. (You can also use pre-drilled holes if you have them.)
  • Use a screwdriver to tighten the screws. If there’s more than one person doing this, it can get tricky! Make sure no one gets in each other’s way or accidentally stands on another person’s foot while they are trying to hang their side of the planter box together with the wooden frame! You may want some help here—or just take turns so that everyone gets to do it themselves at least once throughout construction, no matter how long it takes!
  • Hammer in any loose nails or staples that might be sticking out of your wood planter box frame after lining up all its pieces correctly during construction. Then paint everything where you hammered/nailed/stapled them so they don’t show through when looking at your planter box from afar later on when it has plants growing inside of it instead thanks for reading my blog post today 🙂

Step 5

The planter box is the main structure of your planter, and you’ll want to carefully consider its dimensions before building. The size of your planter box should be about two inches smaller than the actual liner. For example, if your liner measures 24 x 20 inches, then make sure that your planter box measures 22 x 18 inches. This will leave enough room for a 1/2 inch overlap on all sides between the liner and the edge of the frame without interfering with drainage holes or creating an uneven surface that could cause problems later on.

The size of soil in a planted container will depend on many factors: how much sun it gets daily, whether it’s in full sun or partial shade during different hours throughout day (if so), among others things affecting plant growth like temperature changes over time due seasonal temperatures fluctuations too! If there is no specific recommendation given by manufacturer then always choose one-third more than needed — this allows room for growth without having plants sticking out above soil level as well as gives room  for watering without drowning them out completely!

Step 6

  • Make sure the planter box is level.
  • Make sure the planter box is sturdy.
  • Make sure the planter box is the right size.
  • Make sure the planter box is the right height.
  • Make sure the planter box is the right width.

You can make your own planter box and line it to fit in your patio.

You can make your own planter box! You can line it and paint it to fit in your patio. The best part is that you have so many options. You can use a variety of materials, making the box any size you want. And it’s not hard to do at all!

Once you have decided on the dimensions of your planter box, here are some tips on construction:

  • Use 2×4 framing lumber for strength and stability
  • Cut boards for length based on height, leaving about 1 inch extra for trimming later (this will help prevent splintered edges)
  • For corners where two pieces meet , use 3-inch deck screws driven from the bottom side of each board into both ends of another board below it; this prevents movement between boards over time

Once all four sides are assembled (and painted if desired), place top piece over them with a bit more space than needed inside between walls and end caps—this will allow soil to settle as well as create room for plants to grow vertically without risk of damaging plastic liner underneath them


There you go! Now you know how to make a planter box and line it to fit in your patio. We hope this blog has helped you out on your next project.
