Do you have a window in your home that’s a perfect candidate for a window box? I like window boxes because they bring flowers up close so anyone standing at the window can enjoy them. This week, I thought I’d share some DIY plans for a window box that can be constructed in seven steps. You’ll need a workbench or other solid, flat surface, a tape measure, a circular saw, safety goggles, a drill and drill bits, ¾-inch cedar boards, six ¾-inch concrete screws, pressure-treated 2-by-4s, a box of 1¼-inch exterior wood screws, 1 quart of exterior paint, 1 quart of primer, and a large paintbrush. Good luck!
Build a Window Box in Seven Steps
- Use the tape measure to measure the width of your window.
- With the circular saw, cut the cedar wood for your window box. You’ll need three pieces that are 8 inches wide by the width of the window, plus two pieces that are 1¼ inches wide by the width of the window. Now, cut the pressure-treated 2-by-4s into three 8-inch-long pieces.
- The pressure-treated wood will be used to secure your window box to the exterior wall. Hold one 8-inch-long piece against the wall and use the drill to make two pilot holes in the area where you want to put the screws. Put two ¾-inch concrete screws into the pilot holes. Repeat this process with the other two 8-inch pieces of wood.
- Back at your workbench, lay down the cut panel serving as the bottom of the window box. Next, attach one end of the window box to its base using the drill and a wood screw. Attach the other end of the window box to the base before attaching the side panels.
- Once the bottom and all sides are securely in place, flip the window box upside-down and drill a few holes in the bottom. These holes will help with drainage.
- Use the paintbrush to apply primer to all areas of the window box, and let it dry completely before applying paint. If you want added appeal, use a stencil to paint attractive lettering or another design on your window box.
- Once it’s dry, attach your window box to the exterior wall by drilling four screws through the box and into each of the three 8-inch long pieces of wood you attached to the exterior wall in step 3.
Flowers for Your New Window Box
Before getting some flowers for your window box, it’s important to determine how much sunlight the area receives. If your window box gets six or more hours of sun, then you’ll need flowers that like full sunlight. But if your window box gets just a few hours of sunlight per day, then it’s best to buy flowers that thrive in partial sun. Some flowers that love full sunlight include black-eyed Susans, zinnias, petunias, daisies, and geraniums. Flowers that love partial shade include impatiens, violas, begonias, and lobelia. Try some new flowers in your window box each year to give the area renewed interest.
Happy growing, and thanks for reading. – Alan
