Structure and Hardware
The first priority is to make sure that the window box itself is in good condition and has proper drainage. Improper drainage can quickly rot out wooden boxes and potentially damage the wooden siding of your home. Wooden boxes should be inspected yearly and scraped, painted, and repaired as needed before winter sets in. Window boxes with a slanted bottom and a 1/4-inch opening are ideal if you are placing plants directly in the soil in the boxes. You can also place potted plants in the boxes for an easier clean up and less weight in the boxes. Before planting, inspect all hanging hardware and tighten, replace, or repair if needed.
Window Box Style
Traditional or Contemporary?
When choosing your window box and its contents, take into consideration your home’s style, size, and your own gardening preferences. Do you live in a traditional New Englander or Cape? If you do, then traditional window box flower choices are a good pick. Is your home more contemporary? Unusual flower combinations and succulents may be more suited to your home’s architecture. Either way, choose plants and flowers that will complement your home’s color and trim.

Window Box Conditions
Sun and Water
As with all gardening, knowing how much sun the window boxes will be exposed to is crucial for healthy plants. For sunny locations, choose sun-loving and heat-tolerant plants such as geraniums, marigolds, and succulents. Areas receiving more shade are better suited for plants such as begonias and impatiens. How often should you water window boxes? Unless your window boxes are full of succulent plants, which require minimal water, you should always keep the soil moist, but never muddy. Early morning or early evening watering is recommended.
Window Box Planting Tips
Soil and Spacing
To make a statement, choose flowers with bright, continuing blooms in color choices that complement the surroundings. If you are planting your flowers directly in the soil, make sure clean, enriched, well-draining potting soil is used, and loosen plant roots before planting. When using potted plants, make sure the plants are not root-bound in their pots. If they are, consider repotting in containers about 2 inches larger. Place plants close together without crowding, allowing a few inches between each plant for new growth.

Seasonal Accents
Curly willow and pussy willow sprigs add height and complement early spring perfectly. Trailing ivy and moss make wonderful spring and summer window box fillers. In the fall, hay can be used as an accent, as can miniature pumpkins or gourds. Winter window boxes can be made festive with boughs of various evergreens, seasonal berries, and pinecones.
