Additional Information Avoid planting in soil that stays consistently damp or wet. We generally plant 3-4 rows at a time and space out rows at 20-25 cm (8-10”) apart. It is perfect because most people can reach across that width. You can grow 3-4 times the amount of heirloom beans in the same space, you reduce the amount of area for weeds, and you'll save on water. It is about 50-60 days for green beans, 100+ days for dry beans. Beans typically need warm soil of 18°C (65°F) or higher. Grows best in full sun with well watered soil.
