How to Plant a Window Box

Sharing is caring!

A window box is an easy and inexpensive way to add a bit more curb appeal to any home. They can even give a burst of color and life to that old garden shed in the backyard.

My mom has a newly built garden shed in her backyard that was crying out for a pop of color. Fortunately, my dad not only likes to laugh at his own jokes but he loves to make a sawdust mess in the garage and was kind enough to build us two small window boxes that fit perfectly underneath the windows of the shed.

Window boxes bring with them a feeling of nostalgia from way back when. And they’re also super versatile which means you get to be as creative as you want to be!

This is also a really fun project to do with your little ones!


You will need:

  • Windox boxes- you can purchase these at just about any hardware store or garden center.
  • Landscape Fabric
  • Five 4inch potted annuals or one 4inch pot and two 6 inch pots (which is what we used)
  • Potting mix – NOT POTTING SOIL – potting mix is lighter weight and allows for better drainage
  • watering can

Our homemade window box was painted with white outdoor paint to match the trim and to ensure it lasts a bit longer. If you are making your own window box make sure to drill holes in the bottom to allow for water drainage.

Start by lining the bottom of the window box with the landscape fabric. You can staple the sides down if you choose to prevent potting mix from getting inside the edges but it’s up to you.

Next, pour 3-4 inches of potting mix into the window box. Make sure it is even all around.

Remove the plants from their pots and place the plastic pots inside the window box exactly where you want them to go. Press down a bit to make sure the pots are staying upright and to make a “mold”. If you have a taller plant, make sure to put that pot in the middle.

Begin filling the window box with potting mix around the plastic pots. This will create a mold around the pots and will make it much easier when planting.

Make sure to fill the window box close to the top of the pots with potting mix and pack down lightly.

Remove the containers from the potting mix and now it’s time to plant!

A trick to help with the health of your plants is to gently loosen up the roots before planting.

Set your plants inside the window box and fill in any empty spots with extra potting mix. Water your newly planted flowers, hang your window box and enjoy!

You can choose any type of flower you would like but the flowers we chose were flowers that really enjoyed the sunshine because our shed is mostly sun covered throughout the day.

We went with Million Bells in four different colors and for the taller plants in the center of the window box we chose to use a Coleus which is another fast-growing annual.

Gardening is a fun activity for the whole family and definitely brings back a ton of memories for me…mostly just me throwing mud and searching for worms.
