Tips for Year-Round Window Box Success

Plan for All Seasons:
Swap out annuals and add hardy perennials during seasonal transitions. Use evergreens or perennial grasses as your backbone for year-round interest.
Pay Attention to Exposure:
Select sun-loving plants for south-facing windows; shade-lovers thrive on the north side.
Choose the Right Container:
Ensure your window box has good drainage and is deep enough for root development.
Water and Feed Regularly:
Window boxes dry out quickly. Water daily in warm weather and fertilize every 2-3 weeks during the growing season.
Use High-Quality Potting Mix:
A light, well-draining mix allows roots to breathe and minimizes pests or diseases.
Think Vertical and Trailing:
Layering heights creates drama: tall (upright), medium (filler), and trailing (spiller) plants maximize impact.
