Herbs are plants that are grown for their scent and use in the kitchen. Window boxes hang outside during the spring, summer and early fall, and can add color to the home when planted with flowers. Window boxes outside well lit kitchen windows can also be use as small herb gardens. Herbs are well suited to containers, says Virginia Cooperative Extension, because many are drought tolerant, resistant to insects and diseases that afflict container gardens.
Attach your window box to your window using hooks that reach over the window ledge or by screwing the box into the wall, according to the instructions.
Drill drainage holes into the bottom of your window box if it does not have any. Line the inside of the box with plastic. Poke holes into the plastic for drainage.
Fill the window box with a sterile commercial potting mixture and mix in a complete water soluble fertilizer according to the instructions on the box. Fill the container with 1 gallon of potting soil per herb plant, advises Utah State University.
Plant your herbs at the same depth into the potting media as they were buried in their tray.
Water daily to keep the soil moist. Add fertilizer to the soil according to the schedule indicated on the packaging. Moisten the soil before adding the fertilizer to prevent washing away. Fertilize and water in the morning to prevent damaging the herbs.
