DIY Window Box Tutorial

Looking for inexpensive window boxes that still look great? Check out this tutorial for your solution! $10 on a box and $20 on brackets is all you need!

While looking for ways to spruce up our house this summer, I really wanted to add some curb appeal by putting window boxes on our second story windows.

I looked and looked and researched and researched. And after reading review after review, I realized that I could spend $70-$150 on a window box and still not be happy with it.

I hate wasting money on something I could build myself, so I decided to give it a try.

Supplies for Making DIY Window Boxes

• Black Plastic Planter Boxes in the length you need. I used the 36 inch boxes for my windows that are 4 feet wide.
• 2-3 brackets per window box. I used 2 for each of my boxes in the 8 inch width.
• 3-inch Screws
• DeWalt Cordless Drill

How to Make DIY Window Boxes

• On the window where you want to hang your window boxes, find a stud to mount the brackets into while still centering your box on the window.
• Mount the brackets on the wall making sure the box is where you want it.
• Plant the planter box and run drip irrigation for easy, hands-free watering.
• Place the planter box on the brackets.
• Secure the box to the brackets, if desired.

Now, admittedly, I would choose a slightly taller planter box the next time around. They look smaller than I anticipated.

But by the end of the summer, the flowers will be so large that you won’t be able to see the boxes at all. Which was one of my biggest issues when trying to find one to purchase – why pay all that money for something that will be covered up?!

When deciding what to plant in your window box, I recommend trailing plants and low-height plants. You don’t want to obscure your window too much with what you plant.

I love planting flowers that will start to spill over the sides instead of just becoming taller.

The place you do want a little more height is in the center-back of the box. This brings your eyes in and balances out the length of the box and the trailing plants in it.

I organize planting the window boxes like this:

• Back row: spilling, medium height, spilling.
• Front row: spilling, trailing, center spilling, trailing, spilling.
• All the spilling sides plants match.
• The trailing plants don’t have to match.
• The center spilling and the medium height plants are a close color match or related color to the spilling side plants.

I hope this tutorial was helpful and saved you some money! Happy planting!
