How to Grow Strawberries in Window Boxes
- 1). Check that the window box has drainage holes at the bottom. If it doesn't, use a drill to create them.
- 2). Place a 1-inch layer of large gravel or pebbles in the bottom of a deep window box.
- 3). Pour potting soil on top of the gravel. Stop when it is about 2 inches from the rim of the box or two-thirds of the way full.
- 4). Press the potting soil down lightly with your hand. Add more if needed.
- 5). Loosen the roots of your strawberry plants using your fingers and place them in the box. Space the plants approximately four to six inches apart.
- 6). Add more soil, covering the top of the plant roots and leaving the stems uncovered. Use your fingers to firm the compost around the plant.
- 7). Water the plants thoroughly after you've finished planting them. If the roots become exposed, add more soil, but do not cover the crown, which can cause them to rot.
- 8). Place the window box in a window that receives at least eight hours of light a day.
- 9). Water the strawberries daily to keep them moist.
