If You Have a Sunny Window
What to Plant
- 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. So go for reliable bloomers in arresting color combinations. In this box: Dusty Miller (Senecio cineraria Cirrus), Calibrachoa (Calibrachoa Superbells Red), Verbena (Verbena Sissinghurst), and Sweet-Potato Vine (Ipomoea batatas Margarita).
- 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 an 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.
