Tips for Maintaining Beautiful Window Boxes

• Choose the Right Soil: Use a high-quality potting mix that retains moisture but drains well to prevent root rot.

• Water Regularly: Window boxes dry out quickly, so consistent watering is essential, especially in summer.

• Fertilize Often: Use a balanced liquid fertilizer every two weeks to keep plants healthy and blooming.

• Deadhead Spent Blooms: Removing faded flowers encourages continuous blooming and maintains a neat appearance.

• Consider Companion Planting: Mix flowers with trailing greenery like ivy, sweet potato vine, or creeping Jenny for added texture and visual interest.

By selecting the right flowers for your window boxes based on their sun exposure and maintenance needs, you can create a stunning display that enhances your home’s exterior all season long.
