are an ideal way to add a container garden to small spaces. They're also a great way to add color to your home, no matter how much space you have. Before you go filling a window box with soil and flowers, there are a few things to keep in mind.
The standard window box is about three feet long and four inches wide. A box narrower than four inches will not give you enough space to plant multiple plants and create a lush appearance. When choosing a window box, keep the size of your windows in mind. A good rule of thumb is to choose one that is about 25 percent of the window's height.
Window boxes come in a variety of materials, including wood, metal, clay, stone wire and fiberglass. If your windows face the sun, avoid a metal or dark colored window box that will absorb so much heat. If you choose clay or terra cotta, soak the planter box in water first so it does not absorb all the water meant for the plants. Make sure that any window box you choose has drainage holes as well.Use coffee filters over the holes to keep the soil in.
Planting in a window box
follows the general rules of container gardening
. Use a container soil mix and water daily, twice daily in hot weather. Fertilize plants on a biweekly basis and deadhead flowers
as needed to prolong their blooming season. Remember that window boxes aren't only for flowers; they can make a perfect space for herb and salad gardens, too.
