Create a fantastic DIY feature for your backyard or entertaining space with this clever vertical garden made from stackable wooden planters.

What you’ll need
  • 84mm x 19mm timber decking
  • 32mm nails
  • 10mm plastic packers
  • Masking tape
  • Paint or stain
  • PVA exterior wood glue
  • Sandpaper and staples
  • Weed mat
Step 1: Cut your timber to size:

We’ve designed our planters in two different sizes: 600mm and 300mm wide. The lengths of 84mm x 19mm blackwood decking timber for both are listed below. Cut and label each piece, and put them in their groups so you remember where they go. Keep at least eight offcuts to use as spacers.

600mm box: 6 x 600mm (front & back), 3 x 560mm (base),
8 x 275mm (sides & bottom blocks), 8 x 219mm (internal blocks)

300mm box: 6 x 300mm (front & back), 3 x 260mm (base),
8 x 275mm (sides & bottom blocks), 8 x 219mm (internal blocks)

Step 2: Build the front of the planter:

Prepare your workbench by clamping a 750mm wooden block along the back to use as a square. Lay the three pieces of timber for the front of the planter horizontally on the workbench. Place your 10mm plastic packers in-between these horizontal pieces to make sure they are spaced evenly apart. Then place two internal pieces over the top, 300mm apart. Place two spacers against the wooden block at each end of your vertical pieces. Square up the horizontal pieces with another piece of wood.

Step 3: Glue and fix the front of the planter:

Apply PVA wood glue to the horizontal pieces of timber to attach the vertical piece. Put the vertical pieces of timber in place. Use a nail gun to secure the vertical pieces to the horizontal pieces of timber. Mark where the top of each panel is after you have finished them. Repeat the above steps to build the second front for the planter.

Step 4: Build the side and base panels:

To build the first side panel, just follow the same process as before. The only difference is in the spacing between the internal timber blocks, which will need to be closer together. Repeat this process to build the other side panels and base.

Step 5: Put the planter together:

Apply wood glue to the vertical blocks where they will be joined to the side panel. Put the side panel in place and use a nail gun to secure the panels together. Repeat this process until all the sides are attached.

Step 6: Insert the base:

Once the front and sides have been secured, turn the planter over. Apply glue around the edges of the planter and put the base into position. Use a nail gun to secure the base to the front and sides of the planter.

Step 7: Finish off the planter:

You can paint, stain or oil your planter, depending on the look you want. Remember, before you put any soil in, place weed matting down to protect the timber from rotting.
