How to Build a Window Flower Box

Overview

A window flower box filled with colorful and fragrant seasonal flowers adds character to the exterior of your home and is a welcoming sight for both occupants of the house and people on the street. Depending on your personal taste, you can make your window box from wood, wrought iron or any other material instead of purchasing it from a garden supply store. Not only will you save money, but also you can make it according to your personal style. Follow these steps to make a wooden flower box that can brighten up any window.

How to Build a Window Flower Box

Step 1

Measure the window width and determine the length and depth of the flower box. Ideally, your flower box should be an inch or two narrower than the width of the window to allow room for trailing or cascading flowers

Step 2

Select pressure-treated wood that can withstand natural elements since it will be placed outside, and make sure it is at least an inch think to support the weight of the soil and flowers. Cut two equal lengths from the plank for the front and back of the box, and another two for the short sides. For the base, cut a final piece the same length as the front piece and as wide as the short sides.

Step 3

Put the base on a flat surface and place the back piece against it, making sure the joint is even. Staple the two pieces together temporarily. Place one of the short sides against the back piece until it rests securely, using three-quarter-inch nails to screw them together. Repeat the same process with the other short side. Put the front piece in place and secure it with nails after all the corners are even. Nail the back piece securely as well.

Step 4

Turn the box over and check if it is secure before drilling four to six one-fourth to one-half-inch drainage holes in the base. Use a sandpaper to work away any sharp edges or splinters, and apply a coat of acrylic sealant or paint to your window flower box. If you prefer to paint the box, choose colors that complement the exterior of the house and the surrounding landscape.
