How many bean seeds should I plant per hole?

Prof. Charles Hartman, Ph.D.The act of planting bean seeds necessitates consideration of appropriate densities and growth space. I made the mistake of putting 5 seeds per hole, which resulted in all of the plants competing for light which resulted in weak plants and fewer pods. For best yields, I now recommend planting 2-3 seeds per hole and then thinning heavily. Survival of the fittest applies here.
Bush Beans
- 2-3 seeds per hole
- Thin to 1 plant every 4 inches
- Rows 18-24 inches apart
- Overcrowding invites powdery mildew
Pole Beans
- 3 seeds per hole
- Thin to 1 plant every 8 inches
- Rows 30-36 inches apart
- Extra space aids air circulation
Although thinning is both essential and hurtful to do, you simply will not use your hands to snap off plants, you'll use scissors. I once lost three seedlings while disturbing the roots. For bush varieties, when the seedlings are 3 inches tall, choose those if any that are extras. For pole beans, if seedlings are up to six inches tall, choose which one you want to be the strongest climber.
Overplanting
- Symptom: Tangled stems, small leaves
- Solution: Use pelleted seeds for precision
- Tool: Seed spacer templates
Under-Thinning
- Symptom: Yellow lower leaves
- Solution: Thin in stages
- Tool: Micro-tip pruning shears
Utilizing space is a big deal. The 4x8 raised bed I planted contained 18 bush bean plants which outperformed the yields that would have if I planted all 30 plants crowded in their space. With pole varieties, the vertical growth allows for tighter spacing, 8 inches between plants on a 6-foot tall trellis, and produces three times as much per square foot as bush type horizontally.
