Tools Needed
- Circular saw or miter saw
- Drill/driver
- Exterior wood screws
- Measuring tape
- Speed square
- Sandpaper or orbital sander
- Landscape fabric (optional)
- Staple gun
Step 1: Build the Largest Triangle
- Start with the bottom tier. Arrange your boards into a triangle shape and pre-drill all connections to prevent splitting.
- Attach the corners using 3" exterior screws.
- Once assembled, add two small support blocks underneath to help stabilize the planter and keep it level.
Don’t worry if your angles aren’t perfect — plants are very forgiving roommates.
Step 2: Build the Middle and Top Tiers
- Repeat the process for the smaller two triangles.
- Stack them evenly on top of one another, centering each layer carefully. Use vertical 2x4 supports hidden inside the corners to connect each level securely.
- Screw upward through the lower tiers into the supports.
Step 3: Add Soil Supports
Because soil gets surprisingly heavy (seriously, dirt has weight issues), install short 2x4 braces beneath the center of each tier to prevent sagging.
You can also line the inside with landscape fabric to help retain soil while still allowing drainage.
Step 4: Build the Potting Station
- Construct a simple rectangular tabletop frame using the 2x4s.
- Attach the 1x6 boards across the top, leaving small gaps for water drainage.
- Mount the station above the planter using sturdy hinges so it can tilt or fold if desired.
- Add the angled support legs underneath for stability.
Step 5: Sand and Seal
Give everything a good sanding, especially edges and corners.
Apply:
- Outdoor wood sealer
- Non-toxic stain
- Or leave it natural for a rustic garden look
- Cedar is ideal for longevity, but standard SPF lumber works great with proper sealing.
