Introduction: Cedar Planter Box

Picture of Cedar Planter Box

I always enjoy building outdoor projects anyways. I wanted to build something a little different from the usual planter boxes and decided that a sort of Greene and Greene style would be cool.This is really a simple project to build especially if you have a Kreg Jig. I started out with 4 1x4x8 cedar boards from the home store. I cut the short boards on all four sides 3 inches shorter to achieve the look I wanted and inset each end 1 1/2 inches.

Step 1: Materials and Cut List


(4) 1X4X8 Cedar Boards

1 1/4” Kreg Screws

3/4” Deck Screws

Outdoor Wood Glue

Plastic Liner (I used lawn and leaf bag)

Cut List:

(4) 1X4X21”

(2) 1X4X18”

(4) 1X4X11”

(2) 1X4X14”


(2) 1X2X7”

(3) 1X4X9”

Step 2: Assembly

I used 1 inch Kreg screws and outdoor wood glue for the assembly. I drilled pocket holes even across the joining boards and on the end of all the short boards from each side to screw the panels together. I used clamps to help hold the pieces together while assembly. It also helps to make a mark 1 1/2" from the ends of the longer boards to make a reference line for lining up the boards.

Step 3: Making the Bottom

I cut the frame to fit around the bottom after assembly and the same way for the slats, just measure once the box is built and cut to fit. To make the perimeter of the frame I ripped a 1×4 down the middle on the table saw. I assembled the frame with pocket screws and then attached to the box with the same method.

Make sure to leave a gap between the slats for drainage.

Step 4: Fill With Flowers

Once the bottom is in you can line it with plastic( I used a lawn and leaf bag and cut it down to fit) and fill it with dirt and the flowers of your choice!

Step 5: Watch the Video!

great idea i am thinking of making some . but i haven't use pocket screws before when you join the 4*1 together from the sides with the pockets screws does the wood not split and what screws are used for pocket screwing thanks in advance darren

No I haven't had any issues with splitting. Kreg sales their own screws, you can order them online if you want or your regular home store should have them in the kreg section of the tool department. Kreg jig is really simple to use, you set the jig for the thickness your using and along with their self tapping screws you shouldn't have any splitting. The bigger concern is actually not driving them to far and stripping them in the soft cedar.
