Window boxes add instant charm to a home.
But why settle for standard off-the-shelf window box planters when you can make your own window boxes that have beautiful lattice details?
Learn how to build custom window boxes today, and dress up your windows tomorrow.
Materials needed per window box:
8-foot-long 1-by-8-inch cedar planks (7.5-inch actual width)
Two 10-foot-long 1.5-inch white vinyl strips (in window and door trim aisle)
7/8-inch spade drill bit
1/8-inch drill bit
2-inch wood screws
2-inch finish nails
3/4-inch finish nails
White window and door caulk
Staple gun with staples
Weed block fabric
Note: The measurements below are the ones I used for my shed window boxes. Measure your windows first and add at least 2 inches beyond each side of your window frame. I added 3 inches to each side of my window boxes.
Two 26-inch-long 1-by-7.5 inch boards
Two 6-inch-long 1-by-7.5 inch boards
One 2-foot-long 1-by-6-inch board (You’ll need to rip one of your 7.5-inch boards to 6 inches wide for this)
Making your window box planters
Lay out your wood pieces on a flat surface.
Apply wood glue to the perimeter of the bottom piece (shown in center above).
Set the front, back and side pieces in place.
Clamp the pieces around the base to form your box shape. Use 2-inch finish nails to secure the front and back pieces to the sides and the base. For more strength, wood screws will be added next.
Pre-drill three holes into the bottom and two holes into the sides using your 1/8-inch drill bit. Then drive screws into the pre-drilled holes to add additional support to the window box construction. Repeat for the opposite side.
Flip the window box over and drill 7/8-inch holes into the bottom of the window box for drainage.
It’s time to dress up your plain-Jane box. Measure and cut the vinyl pieces to fit around the perimeter of each panel. I suggest making the horizontal pieces full length. Then cut the vertical pieces to fit.
Nail lattice pieces in place with 3/4-inch finish nails.
Measure and cut vertical lattice pieces for the box. Space the pieces evenly, and secure to the front and two sides of your window box with finish nails.
For more detail, cut and secure horizontal pieces to the centers of each framed square.
Fill the nail holes with caulk.
To keep potting soil from pouring out of the holes, staple weed fabric inside the window boxes.
Your window box is complete and can now be hung. Drill and secure your window box into studs or wood supports with exterior wood screws.
Fill with potting soil and flowers.
Water your plants regularly, as they will dry out faster in window boxes.
Enjoy the instant curb appeal boost you just added to your home!
