How long does it take to grow green beans?

Prof. Samuel Fitzgerald, Ph.D.The growing time of green beans varies significantly depending on the variety selected and the growing conditions. Bush beans often mature faster than pole beans, sometimes in as little as two months. The warmth of the soil and the number of hours of sunlight also determine the optimal harvest date.
Variety Selection
- Bush beans mature fastest: 45-55 days from planting
- Pole beans take longer: 60-90 days for first harvest
- Early varieties like 'Provider' bush beans speed results
Environmental Conditions
- Soil temperature below 60°F delays germination significantly
- Consistent sunlight (6+ hours daily) accelerates growth
- Water stress during flowering extends harvest time
Planting Methods
- Direct sowing in warm soil beats transplanting shock
- Succession planting every 2-3 weeks staggers harvests
- Proper spacing prevents disease slowing development
Before planting, check the soil temperature with a thermometer to ensure optimal conditions. Beans will germinate optimally when the soil temperature is between 65°F and 70°F, a process that usually takes 7 to 10 days. In cold soils between 55°F and 60°F, germination takes at least three weeks, indicating that temperature regulates the early stages of growth.
Supply uniform moisture, especially during flowering. Drought stress during this period extends the pod set by approximately two weeks. It is suggested to use either drip irrigation or soaker hoses to maintain uniform moisture in the soil while minimizing moisture on the foliage.
To optimize development, beans must be exposed to the greatest amount of sunlight. Beans grown in less than six hours of sunlight daily will grow more slowly and produce fewer pods. You should cut back neighboring vegetation that shades your beans, and you should amend your planting locations each year to maximize sunlight exposure once again.
To achieve quick results, select the fast-maturing bush types. The 'Contender' beans, for example, can produce edible pods roughly 45 days after starting seeds, assuming good gardening care. These beans grow well in succession plantings, providing continuous harvests throughout the season.
