This step by step woodworking project is about wooden extra deep elevated planter box plans. If you want to grow vegetables with roots (carrots, celery, potatoes, etc.) this planter box will fit your needs like a glove. Make sure you invest in weather resistant lumber (cedar, redwood), as the components will be exposed to the weather elements. See my other DIY projects HERE.
We recommend you to invest in the best materials you could afford. Therefore, you should buy weather-resistant lumber, such as pine or cedar. Always take accurate measurements before adjusting the size of the components at the proper size. Drill pilot holes trough the components before inserting the wood screws, to prevent the wood from splitting.

How to build a raised planter box
The first step of the project is to build the legs for the planter box. Cut the legs from 4×4 lumber at 30″ and then make the notch to the top using a circular saw. Make parallel cuts inside the marked area and then remove the excess with a chisel. Smooth the recess with sandpaper.
Use 2×10 lumber for the planter box. Cut the slats at the right dimensions and then lock them together tightly with 2 1/2″ screws. Drill pilot holes before inserting the screws to prevent the wood from splitting. Make sure you align the edges and check if the corners are square.
Attach the legs to the two boxes. Leave no gaps between the slats and align everything with attention. Drill pilot holes through the slats and insert 2 1/” screws into the legs.
Fit the 2×10 slats inside the planter box. Align the edges at both ends, drill pilot holes and insert 2 1/2″ screws to secure them into place tightly.
Attach the 2×2 cleats to the interior of the planter box. Align the edges with attention, drill pilot holes and insert 2 1/2″ screws, every 4″, to lock them into place tightly.
Fit 1×4 slats to the bottom of the elevated planter. Place a piece of 1/2″ plywood between the slats, so you create even gaps. Drill pilot holes and insert 1 5/8″ screws, so you lock them into place tightly.
Use hardware cloth for the bottom of the planter box. Cut the cloth to the appropriate dimensions (21″x41″) and then staple them to the slats.
Last but not least, you need to attach the trims to the top of the elevated planter box. Use 1×6 lumber and 1×2 lumber for the trims. Align the edges with attention, add glue to the joints and insert 2″ nails to lock them into place tightly.
Fill the holes with wood putty and then smooth the surface with 120-220 grit sandpaper. Make sure you check all my planter plans HERE. If you like my project, don’t forget to SHARE it on Facebook and Pinterest.
