How To Choose A Window Box?

Window boxes can be made from different materials like brick, metal, vinyl, wood, fiberglass, and cellular PVC. Wood is a popular choice because it looks nice and can last 10-15 years if you take care of it. Fiberglass is another good option because it’s light and bugs can’t damage it. Cellular PVC and vinyl are made of plastic and won’t rot, making them great choices too. To pick the right size, the window box should be about a quarter of your window’s height.

How To Plant Window Boxes?

First, pick your window box and decide where to hang it. Remember, a window box filled with soil and plants can be very heavy, especially when wet. Make sure it’s sturdy and use a strong bracket to hang it. Your window box should have drainage holes to let water out. When planting, leave some space between each plant so they have room to grow. Choose plants that need the same amount of water and sunlight. You’ll need to water them more often than plants in the ground. Water them well when the soil feels dry.

Look at your yard for ideas and maybe use one color for all your plantings. If your window box hangs near an outdoor dining table, tuck in fragrant herbs like thyme, oregano, and mint as fillers.

Maintenance Tips

Ensure your window boxes are easily accessible for frequent watering. Window boxes dry out faster than ground plants, so they may require daily watering during hot weather. Use self-watering inserts or add a layer of mulch to retain moisture.

Regularly prune and deadhead your plants to encourage new growth and prolong blooming periods. This also helps maintain the overall appearance and health of your window box​. Feeding is crucial for the health of your plants. Use a slow-release fertilizer or a liquid feed every couple of weeks to keep plants thriving.
