Place Plants in Position

Place the plants in their original pots in the windowbox and make sure that they will sit about 1 in (2 cm) below the rim when planted to allow sufficient space for watering.

Plant Up and Firm In

Plant up and fill in around each plant with soil, firming it in with your fingers as you go. Water well. Water your box once or twice a week in winter, and more frequently in spring.

Extend the Season

This colorful windowbox makes a bright winter display with a mixture of pansies and textured evergreens. Then, as the weather starts to warm up, blue grape hyacinths and dainty daffodils (not in flower here) appear in succession to keep the interest going throughout spring.
