One to three green bean seeds per hole is ideal for most varieties.
Plant one to three green bean seeds per hole, spaced 2-4 inches apart in rows 18-24 inches apart. For pole beans, plant seeds 1 inch deep; for bush beans, plant 1-1.5 inches deep. Germination typically occurs within 7-10 days under optimal soil temperatures of 70-80°F. Thin seedlings to 3-4 inches apart if multiple seeds sprout in a single hole.
Planting depth and spacing for green beans
- Bush beans: 1-1.5 inches deep, 3-4 inches between plants
- Pole beans: 1 inch deep, 4-6 inches between plants
- Row spacing: 18-24 inches for both types
Germination rates and thinning guidelines
| Method | Seeds per hole | Germination rate | Thinning needed? |
|---|---|---|---|
| Single seed | 1 | 80-90% | No |
| Double seed | 2 | 95-98% | Yes |
| Triple seed | 3 | 99%+ | Yes |
Soil temperature and planting time
- Optimal soil temp: 70-80°F (21-27°C)
- Minimum soil temp: 60°F (15°C)
- Planting time: After last frost when soil warms
Common mistakes to avoid
- Planting too deep (reduces germination)
- Overcrowding (competes for nutrients)
- Planting in cold, wet soil (causes rot)
