Many people are choosing to grow at least some of their own food for nutritional and financial reasons. Even those who have little space can grow vegetables in containers. Green beans are a perfect choice for growing in a window box. There are two types of green beans available. Pole beans are vining and need support for proper growth. Bush beans form a compact plant that will not need extra support. Bush beans will be easier to grow in a window box. The North Carolina Cooperative Extension Service recommends the Bush Romano, Bush Blue Lake and Tender Crop varieties.
Inspect the bottom of the window box to make sure that drainage holes are present and fully punched out. Use a drill to add more holes as needed.
Measure to calculate how many bean plants can fit in the window box. Bush beans should be planted 2 to 4 inches apart, according to the University of Illinois Extension.
Add potting soil to the window box until it is just below the top edge. Tamp down the soil but do not pack it tightly.
Use an index finger to poke holes 1-inch deep in the soil where each bean plant will be. Place 2 to 3 bean seeds in the hole and gently move the soil to fill in the hole.
Moisten the soil in the window box. Check the soil daily and water when needed, making sure the soil does not dry out.
Thin the seedlings after they have germinated and grown for a couple of weeks. Select the strongest plant and snip off any others with scissors near the soil surface. Don't pull them out, as this may damage the roots of the remaining plants. Plants should be 4 inches apart, New Mexico State University advises.
