Share
Have you ever crave for a Pinterest-worthy planter box that will cradle your favorite leafy monstera with all the care it deserves? Then this D.I.Y project can give your green babies a special home. Let's tackle this project like a pro with our trusty circular saw!

Materials You'll Need To Get Started With Your Custom Planter Box
To build your planter box, you’ll need:
- Circular Saw (Your new best friend!)
- Plywood or timber [Recommended Size for this tutorial:3/4 inch]
- Measuring tape and a pencil
- Straight-edge guide and clamps
- Safety gear (always!)
- Sandpaper, wood screws, and a screwdriver
- Paint or wood stain (optional but oh-so-pretty!)

Step-by-Step Guide:
Step 1: Visualize Your Planter Box Design
For this tutorial, we’re building a 24-inch (60cm) long x 12-inch (30cm) wide x 18-inch (45cm) high planter box.
This size works great for medium-sized plants or a small herb garden. You can place it by a sunny window, on your patio, or in your garden.
Step 2: Measure and Mark Your Plywood
Using a 3/4-inch (19mm) thick plywood sheet, mark the following panels:
- 2 Long Side Panels: 24 inches (60cm) x 18 inches (45cm)
- 2 Short End Panels: 12 inches (30cm) x 18 inches (45cm)
- 1 Base Panel: 24 inches (60cm) x 12 inches (30cm)
Pro Tip: Use a straight-edge guide and pencil to draw precise lines. Double-check all measurements before proceeding to cut!
Step 3: Time to Cut
Set Up Your Workstation:
- Secure the plywood on a stable surface with clamps.
- Wear safety goggles, gloves, and a dust mask.
Adjust Your Circular Saw:
- Set the circular saw blade depth slightly deeper than the plywood thickness (around 1 inch).
- Follow your marked lines carefully, keeping your cuts slow and steady.
- Use a straight-edge guide to ensure clean, straight cuts.
After cutting, you’ll have five panels: two sides, two ends, and one base.
Step 4: Assemble Your Planter Box
What You’ll Need:
- Wood screws (1.5–2 inches long)
- Drill or screwdriver
- Clamps
Steps:
Attach the Sides to the Base:
- Position the base panel flat and align one long side panel along its edge.
- Drill pilot holes to prevent the wood from splitting, then attach using screws.
- Repeat for the other long side panel.
Attach the End Panels:
- Align the short end panels at each end of the base and side panels.
- Drill pilot holes, then secure with screws.
Check for Stability:
- Tighten all screws and ensure the planter box is sturdy and well-aligned.
Step 5: Add the Finishing Touches
Sand the Surfaces:
- Smooth the edges and surfaces with sandpaper or an electric sander to remove splinters.
Apply a Finish:
- For outdoor use, apply a waterproof sealant, paint, or wood stain.
- Allow the finish to dry completely before adding soil and plants.
Optional: Add drainage holes to the base panel (about 4–6 evenly spaced holes) to prevent waterlogging.
Your Planter Box is Ready!
Place your planter box in its new home, fill it with soil, and add your favorite plants. Admire the professional look of your DIY masterpiece and the happy, thriving plants inside!
Pro Tip: Line the inside of the box with plastic or landscape fabric to protect the wood and make cleaning easier.
There’s nothing more satisfying than crafting something beautiful and practical with your own hands, especially when it’s a custom planter box for your beloved plants. With a circular saw and a little creativity, you can transform a simple piece of plywood into a stunning home for your green babies.
