For planting beans, spacing depends on the type of bean (bush or pole) and the planting method: Bush Beans:
- Plant seeds about 4 to 6 inches (10-15 cm) apart within the row
- Rows should be spaced about 18 inches (45 cm) apart to allow for access and airflow
- When planting in blocks rather than rows, spacing of 6 to 8 inches apart in all directions is recommended to facilitate weeding and harvesting, with 8 inches being easier to manage
- Some gardeners find that spacing bush beans 6 inches apart works well for hoe access, but 8 inches is more comfortable and reduces disease risk
- Seed depth is typically about 1 inch deep
Pole Beans:
- For pole beans, plant seeds about 3 to 4 inches apart, with rows or supports spaced about 18 inches or more apart
- When using supports like poles or teepees, place 4 to 6 seeds at the base of each support, spacing the supports about 3 feet apart
- Seeds should be planted about 1 inch deep
Additional Notes:
- Planting beans too close (e.g., 3-4 inches) can lead to competition for nutrients and water, shading, and increased disease risk, potentially reducing yield
- Wider spacing can improve airflow, reduce pests and diseases, and make harvesting easier
- For dry beans, tighter spacing is less problematic since the whole plant is often pulled at harvest, but for green/snap beans, more space aids harvesting
In summary, a good general guideline is:
- Bush beans: 4-6 inches apart in rows spaced 18 inches apart, or 6-8 inches apart in block plantings.
- Pole beans: 3-4 inches apart with supports spaced about 18 inches to 3 feet apart.
Adjust spacing based on your garden size, climate, and whether you want to harvest green beans or dry beans
