|'Blue Coco' is an heirloom variety, generally ready for harvest 60 days after sowing. The vines grow 8 to 9 feet long, and are quite resistant to bean beetles. The flowers are particularly pretty, rose-pink in color. The leaves are tinged purple, and the pods themselves are dark purple. The beans are snap, and their purple color fades to green on cooking. Mature seeds are chocolote-colored, with a rich, meaty texture.
This group of beans is a favorite for the home garden and can be grown just about anywhere because they have a relatively short growing season. They can be planted from seed as soon as the soil is warm (day temperatures are around 60 degrees Farenheit), in full sun and loose, well drained soil. Bush type beans are very easy to grow and manage, reaching a height of only 2 feet tall. To control harvest, bush beans can be planted every two weeks. To decide how many crops you can plant, divide your growing season by the maturation period of the variety you are planting.
When preparing soil, be sure not to mix in too much nitrogen (5-10-10 is best) or you will get all plant and no beans. 1 pound per 100 square feet is plenty. There is no need to soak beans prior to planting and no need to heavily water right after planting. If coat is cracked too early, germination may be poor. Beans should be planted about 1 inch deep and two inches apart, with rows at least 2 feet apart. Pole type beans should be planted at least 4 inches apart, 6 inches being better, and have rows 3 feet apart. Pole beans will require some type of trellising system, with the tee pee system working quite well. It is alright if beans are a little crowded, as they lend each other support, however, thinning to 4 inches is best.
