About window flower boxes

Window boxes first graced the lower class homes in ancient Rome. Because they had little to no space for gardening, the window boxes became their source of food and herbs. The idea of using window boxes caught on with the upper class and eventually spread to homes throughout Europe. Eventually, the use of window boxes came to colonial America. 

Choosing a flower box

Consider how the window box will fit in architecturally with your house design. The box should fit the width of the window or the window plus the frame. Use two or more boxes side-by-side for a wide window. If you want the box to favor your window trim, look for paintable boxes. When in doubt, go with black wrought iron into which you can add a plastic container or simply place potted plants. The box will come with directions on how to hang it, like using brackets or screwing the box into the wooden window frame or the side of the house.

Choosing the plants

A window box can contain flowers and other plants, like ornamental grasses or herbs. Plants that grow to the same height are pretty, but for a spectacular view, try plants of varying heights and shapes. Choose colors that will also compliment the paint color in the room that looks out over the window box. When you place the plants in the box, consider how much the plants will spread as they grow. You can get that information from the tag on the plants. Initially, your planter will look a little sparse, but it will fill in as the plants grow and expand. Placement of the plants in the box is a matter of taste. So place large plants in the middle, small on the ends. Others will make every other plant a taller plant, while still others will place the larger plants on the outer ends of the box, with smaller plants in the middle. You can’t go wrong.

·         Herbs. Herbs that do well in window boxes:  basil, oregano, parsley, rosemary, thyme.

Theme window boxes

You can add objects to the flower box to reflect your personality or the season. Add whimsy with small USA flags on sticks, ceramic statues, tiny pumpkins to compliment a mum filled box, whirligigs, dainty lawn ornaments, miniature pink flamingos, weather vane, or birdhouses on sticks. Many things have the potential to become window box ornaments. The object just needs to be waterproofed; you can then hot glue the object to a pencil or dowel so the object peeks through or hovers above the flowers. Visit a craft store for hundreds of ideas.
Caring for the plants

Your spectacular window box needs continuous maintenance. Use moisture-retaining, self-fertilizing potting soil. Remember to water them. The box may need to be watered twice a day when it’s hot and sunny. Pinch off the heads of flowers that have finished blooming. If your area receives a lot of rainfall or the box is in the shade, you should remove the drain plugs in the bottom of the planter. If necessary, drill holes in the bottom to allow excess water to drain. Your window box can flourish into the fall, longer if you live in a warm climate.
