How to Attach Flower Boxes to the Window


Adding a window box to the front of a home increases curb appeal and creates a cottage home look after flowers are planted. Hang the boxes under windows by attaching them directly to the wall of the home. Wooden window boxes are sturdier and have a longer life span than plastic ones. Use a plastic liner to increase the lifespan and prevent water damage. Purchase bolts to hang window boxes at stores that carry hardware supplies.

Step 1

Prepare the window box by drilling 1/2-inch diameter holes into the top corners of each box, 1 inch from the top and side of the box. Add a center hole for more support if the box is longer than 30 inches.

Step 2

Mark the hole location on the house by holding the box in the desired mounting position and placing pencil marks at the location of each hole.

Step 3

Install a hanger bolts at the location of each pencil mark. Drill a 1/2-inch diameter hole into the house and screw the hanger bolt in so there is approximately 1 1/2 inches sticking out.

Step 4

Slide the window box onto the hanger bolts so the bolt extends to the inside of the box through the drilled holes. Secure the box to the house by placing a washer onto the hanger and screwing a nut tightly in place. The wall of the window box is sandwiched between the house and a bolt nut.
