Assembling the flower box

Assembling the flower box

The first step of the project is to assemble the frame of the flower box. As you can see in the image, you need to cut the 1×4 slats at a proper size and lock them together to the 2×2 corner posts.

In order to get rigid joints, we recommend you to drive in 2” wood screws trough the interior of the flower box, after drilling pilot holes. Check if the corners are right-angled, using a carpentry square.

If you want to enhance the look of the flower pot, we recommend you to cut out several shapes on the front and side faces of the flower box. Use a jigsaw to cut out the rhombs , as in the image. Smooth the cut edges with a fine-grit sanding block.

Fitting the bottom of the box

The next step of the woodworking project is to build the bottom of the flower box. As you can see in the image, you need to attach two 1×2 wooden pieces to bottom of the front and back faces of the flower planter.

Top Tip: Attach 1×4 slats over the cleats, as in the plans and secure them into place with 1 1/4” galvanized screws. Make sure you place the slats equally spaced, leaving between them about 1/4”.

Installing the trims

Installing the trims

Cover the top edges of the flower box with 1×2 trim, as in the image. If you want to enhance the look of the planter and to get a neat design, we strongly recommend you to fit them into place. Use finishing nails to secure the trims into place after aligning them with attention.

Top Tip: As we have already pointed out, round the exposed edges of the trims with a router or make them smooth with a sanding block.

Last but not least, you need to take care of the final touches. As you might imagine, you have to fill the holes and the cracks with wood filler. Let the compound to dry out for several hours, before smoothing the surface with 120-grit sandpaper.
