Approximately 2-4 seeds per gram. Phaseolus vulgaris Lot# BD23100 Black Turtle Bean is an old heirloom variety that was introduced in the late 1700's. Dry pods have beautiful, vivid jet black plump seeds. The bush variety bean are heat resistant, and have a good disease tolerance. Plants can grow between 45-51 cm (18-24”) tall and have an average spread between 30-40 cm (12-16”). Typically they are grown to harvest the dry beans that are used in black bean soup. Matures in 90-100 days.
Direct sow from end of May to June 15th preferably but can be sown into the beginning of July. Try to plant during a warm, dry spell. Soil must be warm. If it is not warm enough, seeds will rot. Beans require a minimum soil temperature of 16°C (60°F) and a maximum of 24°C (75°F). Seeds will not germinate properly if planted too deeply or too early in cold wet ground. Sow seeds 2.5 cm (1") deep, 5-8 cm (2-3") apart, in rows 45-60 cm (18-24") apart.
Soil Conditions: Well worked rich, loose and well-drained soil. Ideal pH: 5.5-6.8
Planting Depth: 2-5 cm (1") deep, 5-8 cm (2-3") apart.
Germination: 7-14 days.
Height at Maturity: Plants reach 45-51 cm (18-24”) tall. Compact bush habit. Spread between 30-40 cm (12-16”) wide.
Days to Maturity: 90-100 days for dry beans.
Watering:Low water requirements at planting- moisten soil for germination, medium at flowering and then heavy through harvest.
Sun/Shade: Full Sun
Seed Spacing: 5-8 cm (2-3") apart, in rows 45-60 cm (18-24") apart.
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. Beans typically need warm soil of 18°C (65°F) or higher. Grows best in full sun with well watered soil. Regular harvesting of the young pods will ensure a greater yield. Pick frequently for maximum yields, but avoid disturbing foliage in wet weather to prevent spread of fungal diseases. White-seeded beans usually don’t germinate as well as dark-seeded.
