Germination: 4-10 days
Germination Temperature: Optimum soil temperatures 70-85 degrees F.
Seed Sowing Depth: 1” deep
Outside Sowing: After last frost with soil temperatures above 60 degrees F. Sow 3- 4” apart for trellis/pole growth. Planting in soil under 60 degrees results in poor germination.
How much does a packet plant: 15 foot single row
Harvest: Before the seeds bulge and beans snap easily. Pick continually every 2-3 days to prolong production.
Tips: Grow in light, well-drained soil, provide adequate, even moisture, especially at flowering time. Dry soil can result in low yields and fibrous pods. Do not over fertilize with nitrogen which results in a surplus of foliage and low, delayed pod growth. Adding inoculant at planting time aids in a larger harvest and more robust plants.
