How to Make DIY Window Flower Box

My house used to be the prettiest on the block. But then I got into blogging and that takes up tons and tons of time. The outside of my house isn’t nearly as lovely as it used to be as a result. It needs to be repainted and the gardens have gone haywire. But since I’m going to be selling my home soon all of this stuff must be done blogging be darned. I’m focusing on outdoor planters, wood planters, and wooden planter boxes (hence, today’s post).

My mother and I will soon be tackling these overgrown monstrosities and my father and I painting the exterior. But until then we thought we’d work on some projects to add a little bit of charm back into the facade of my home and super cute window boxes seemed an easy and inexpensive way to amp up my little house’s curb appeal!

HOW TO MAKE WINDOW BOX PLANTER

First things first, you’ll need to tackle that cut list. Because these are outside, we went with cedar boards.

And a quick tip, if you measure out your boards off of the others you’ve cut of the same size, you’ll have less room for error than if you simply measured the cuts out with a tape measure!

Space out your pots on your board as you’d like them. Measure to be sure they are equidistant and then trace the pots onto the wood. Because the hole will need to be smaller than the pot, draw within the tracing your cut line.

Using a drill make a hole along your cut line. This gives entry for your jigsaw.

Cut out your first circle.

And check to make sure your pot fits.

Use the cut-out to make holes the same size down the length of the board.

And if you’re worried that your holes aren’t perfect circles, don’t be. This guy isn’t bothered.

Run a bead of Liquid Fusion glue down the front side. Now you can use any super strong glue rated for wood but my dad and I are all about the Liquid Fusion right now!

Nail one of your 41 3/4″ boards onto the side of your top (with the circles). Make the board flush with the top side before nailing in.

If your nails come through the cutouts, simply hammer them down.

Repeat and add the board for the second side. Depending on which piece of wood is prettiest, either side can be the front or back at this point.

Run glue along the sides and edge of the box. (and you can do the fancy mitered corners like this if you choose, but straight cuts will work out just as well and be much easier to do)

Attach your board with finishing nails. Repeat for the last side.

Now these shelf brackets are made of oak. Be sure to stain or seal these for longevity since they will be outside and near water.

Trace the bracket along the backside toward the bottom of the box.

Make several cuts within that area that needs to be removed up to the stop line.

Use a hammer to knock out the wood to make your space for the bracket to fit into.

Place the bracket within with the top edge poking up just a bit higher than the bottom. This slope will allow the window box to sit at a slight slant when placed on the window meaning water will run down the wood and not pool right up against your house where it could do some damage.

Run nails through the top side down to the bracket to hold into place. Repeat for the bracket on the other side of the box.

To hang run long screws into the side of your house, using a measuring tape to be sure you get the box nice and centered.

And in case you were wondering about that slope from angling the brackets, here it is!

To make these window boxes perky and full without having to wait, we purchased 2 large hanging baskets and broke them up to fill the four pots.

Be sure to give the plants good watering after moving them to your pots.

And enjoy your new window boxes!

I just LOVE how this perks out the side of the house!

Flowers are always a welcome addition to the facade of a home. Plus they look so pretty when looking out of the window!

And as an extra bonus, kitties love being even more hidden when stalking the outside creatures from the inside!

All in all, each window box should take about an hour to complete, along with planting your new flowers. Not bad, I’d say!
