Beans 'Dragon Tongue' (Beans)

Wait until the frost-free date for your zone AND until the soil has warmed to above 60F (15C).
Plant seed one inch (2 cm) deep (as deep as the bean is long), in rows 18 (45 cm) to 36 (90 cm) inches apart.
Plant directly in the garden, and don't start indoors since they don't transplant well. Soaking beans is not necessary and, in fact may damage seeds. Inoculating seeds with rhizobium bacteria may increase yields, especially where beans have been grown.
Plant successively through July, but in the height of summer pod, when temperatures are above 90F (32C), pod set weakens.
Keep evenly moist (about 1 inch or 2 cm / week, like a lawn) especially when plant is in bloom and developing pods. Deformed pods may be the result of insufficient moisture, poor soil fertility or insect damage during bloom. Drip irrigation is best, since wet foliage promotes disease. As with most vegetables, water early in the day so any moisture on foliage dries quickly. Do not use nitrogen fertilizers since you will get excessive leaf production instead of fruit. Best practice is to rotate crop position in the garden every three years.
