Gardeners generally divide bean varieties into three main categories, depending on the stage at which they're usually picked and eaten: snap, shell and dry. All are easy to grow, and all need the same growing conditions - the prime one being plenty of warmth.
Often called green beans or string beans, the common garden bean can be both stringless and colors other than green. But it’s the green bean that everyone recognizes as one of the most frequently prepared vegetables. Hot, cold, even raw, string beans are versatile in the kitchen and very prolific producers in the garden.
Seeds or Seedlings Germination:8 to 10 days, 70F to 80F
Seed Life: 5 years
Soil: Well Drained
Plant Bush Beans 1" to 2" apart. Pole Beans 3" to 4" apart
Beans are generally direct seeded in the garden. The most important point about growing green beans is not to plant them too early. They will rot in cool, damp soil. To get an earlier start, you can put down black plastic, to warm the soil.
Bush beans begin producing before pole beans and often come in all at once. Staggered planting, every 2 weeks, will keep your bush beans going longer. Pole beans need time to grow their vines, before they start setting beans. The pole bean crop will continue to produce for a month or two. Beans like a moderately rich soil with a slightly acidic pH of about 6.0 to 6.2.
They prefer a loose, moist soil. Plant after all danger of frost is past.
Plant bush beans in either rows or blocks, with 4-6 inches between each seed. Plant the seeds 1-2 inches deep and be sure to water the soil immediately and regularly, until it sprouts.
Pole beans will need some type of support to grow on. Be sure the trellis, teepee, fence or whatever is in place before you seed. Plant seeds at a rate of about 6-8 seeds per teepee or every 6 inches apart.
Pole beans may need some initial help in climbing. Keep the bean plants well watered. Mulch helps keep their shallow roots moist. Long producing pole beans will benefit from a feeding or a side dressing of compost or manure about half way through their growing season.
