Bright, showy flowers are at their best in a box that gets at least six hours of direct sunlight between 10 a.m. and 6 p.m.

What to Plant

Go for reliable bloomers in arresting color combinations (such as hot pink verbena and red calibrachoa). To add contrast, set the flowers against a backdrop of foliage in a variety of colors and textures.

When to Water

Daily, depending on rainfall and the season. To be safe, water when the soil feels dry one inch down.

How to Maintain

Add a balanced water-soluble fertilizer every two to three weeks for extra growth potential. If you see spent blooms, pinch them off so the plants can flower more prolifically.
