Since the day we moved into our house over three years ago, I’ve been wanting to install a window box on our home. We have the perfect spot for one. Well, this past week I finally made it happen!
I purchased a 48″ white vinyl window box from Wayfair. It’s awesome because it has a hidden reservoir in the bottom so I won’t have to water the flowers as often. It came with great directions on how to install it. The same self-watering window box also comes in 36″ and 60″ lengths and several different color options. There are tons of other amazing types of outdoor planters too, so definitely browse around Wayfair’s site.

1. Decide on placement and mark where the L-brackets should go.
2. Mark the holes where you’ll drill.
3. If you are attaching it to brick, you’ll need to buy masonry screws and a special masonry bit. I bought these at my local home improvement store.
4. Carefully pre-drill holes, keeping the drill at a 90 degree angle.

5. Attach the two outside brackets using masonry screws.
6. Use a level to ensure the two center brackets are correctly placed and attach them too.
7. Slip the window box onto the brackets and make sure everything clicks tightly into place.
8. Ta-dah! That’s all it takes to hang a window box!

To celebrate Earth Day, Wayfair challenged me to find a way to take better care of our planet. I decided to increase the number of flowers in my yard and plant bee-friendly plants to do my small part to encourage a healthy bee population.

Bees are so incredibly important to our planet. If the bee population shrinks too much, plants would be unable to be pollinated and eventually we would have a food shortage. In our modern age, we tend to kill off crucial bee food sources like dandelions and clover.

So what can we do to encourage the bee population to thrive, even as we spray our yards to keep out weeds? Replace those vital food sources with plants that are pretty and bee-friendly!

Below is a list of bee-friendly flowers that work well in window boxes.

To make a stunning flower display, you’ll want to plant thrillers, fillers and spillers. Thrillers are the tallest plants in the box, ranging in size from 12-18 inches. Fillers have smaller flowers, don’t grow as tall and fill in the gaps around the larger thriller plants. Spillers are trailing plants that will “spill” out the sides and add volume and drama to your window box. Including all three types of plants is a proven way to design a gorgeous planter.

For my window box, I chose geraniums as my thriller, sweet allysum as my filler and verbena as my spiller. They don’t look like much right now, but once they grow and fill in, it’s going to be so pretty!

We still have a ton of work to do on the outside of our house. The faded brown paint in the eaves has got to go and I want to repaint the balcony railing. And get a new front door. And add more flowers to the flower beds. And replace the two slot windows with one big picture window. And while we’re at it, I’d love to just re-side the entire house and get a new roof… and the list goes on. But look at what a difference it makes just adding the window box, pulling weeds and filling the flower beds with fresh bark…
