Window Boxes

It was during the Roman Empire when the use of window boxes started. This form of gardening was used even by the most modest homes to maximize growing area intended for medicinal plants and herbs and to plant vines and flowers in elaborate displays on rooftops and balconies. In the past, only the wealthy Romans could afford to have window boxes.

Window boxes are a form of a container in gardening that adds charm and brightens the window of any type of home. Want to know how you can build beautiful window boxes? Continue reading and find out how.

Steps on How to Build Window Boxes

Here are steps on how to create lovely window boxes that can make your home more appealing.

Step 1 – Choose the Right Container

Some of the popular containers include plastic, fiberglass, and terra cotta. However, the most commonly used container for window boxes is one made of wood. Redwood and cedar containers are very resistant to rot and can insulate the soil from heat.

Be careful in using metal, as it tends to become very hot and can cook your plants, particularly if placed in a sunny location. It does not matter which container you choose, though you want to make sure the color will complement the trim and siding of your home.

The length of the box should not be longer than the window. The size of the box is likewise important. If you use smaller window boxes, you need to water more-frequent since the container can dry out fast. The ideal size of a window box is 8 x 8.

Step 2 – Installing the Window Box

Before installing the window box makes sure the box has drainage holes underneath or else the plant will not survive because of excessive moisture. Secure the box in its permanent place before you add soil to it. Mount the box with steel brackets 18 inches apart. If your house has brick veneer masonry, use screws to secure the box in place. You can also use a chain to attach the box to the window frame.

Step 3 – Placing Plants in the Box

The next step is to place a liner in the box. This will prevent the soil from getting in contact with the container. If your box is made of wood this step can help your container last longer. Another option is to place potted plants in the container or you can put soil directly in it. Use decorative material like Spanish Moss to conceal the pots. If you choose to put the soil directly or use a liner, make sure to leave a space around 1” from the top of the box to the soil line.

Step 4 – Choosing Plants

Choosing bright colored plants will usually show better than lighter colored and pale colored plants. A white colored plant is preferred if your window box is next to brick walls. It is also nice to have plants that will cascade over the edges of the box like lobelia, petunias, or sweet alyssum and plants like geraniums. Make sure plants are not so tall they block the window. If you placed the window box outside the kitchen, you can plant herbs like parsley, thyme, and oregano.

After setting up your window boxes, the next thing you need is to water them regularly, especially during the summer season. Feed plants twice weekly or as needed, depending on your chosen plants. Also, routine grooming will make the plants look at their best. Window boxes are a lovely compliment to a home, and as you can see, easy to create and maintain.
