In the Garden:
These tender beans escaped being eaten during harvest; I'll boil them briefly and enjoy them with a pat of butter.
Growing the Best Green Beans
Green beans are the second most popular vegetable grown in home gardens, but I'll bet they're first in terms of being the easiest ones to grow. So easy, in fact, that planting beans is a great way to introduce youngsters to the fine art of gardening. Just like Jack, you'll be able to watch your magical beans grow and grow. And though you may not be able to climb them up into the clouds, you will be rewarded with one of the best taste treats of summer.
Garden beans can be broken down into three general groups based on when they are eaten: snap beans, fresh shell beans, and dry beans. Snap beans are eaten whole, including the pod and the small, immature seeds. They were formerly called "string beans" because fiber developed along the seams of the pods. These fibers have been reduced through selective breeding, and the result is a tender pod with no strings at all. Dry beans are the dried mature bean seeds, and are appropriate for long-term storage. Fresh shell beans are somewhere between snap beans and dry beans. They are most often eaten fresh, with nearly mature seeds that have been removed from the pod but not yet dried.
When to Plant
Beans can have either a vining growth habit (pole beans), or a compact growth habit (bush beans). All beans have similar growing requirements: full sun and a well-drained soil rich in organic matter. Beans are warm-weather crops and won't tolerate cold temperatures and frost. In our region they should be planted after April 15th.
How many seeds should you plant? A good estimate is 5 to 10 feet of bush beans for a family of four. Since plants only produce for two to three weeks, you may want to do more than one sowing. You can assure yourself a continuous supply of snap beans by planting some seeds every two to four weeks until early August.
Pole beans produce a bigger crop than bush beans, and they are a good space saver for small gardens. However, they also take longer to mature.
Spacing and Depth
Beans do not transplant well, so plant seeds directly in the garden. Seeds of all varieties should be planted 1 inch deep. Sow seeds of bush beans 2 to 4 inches apart in rows at least 18 to 24 inches apart. Seeds of pole beans should be sown 4 to 6 inches apart in rows 30 to 36 inches apart, or in hills (four to six seeds per hill) 30 inches apart.
Seeds of most bean varieties tend to crack and germinate poorly if the soil's moisture content is too high. For this reason, never soak bean seed before planting. Instead, water just after planting or plant right before a rainstorm.
It's best to pull weeds by hand before they become large enough to compete with the bean plants, and use care when cultivating around the plants because they have shallow roots that are easily injured.
Harvest when the pods are firm, crisp, and pencil-sized, but before the seeds within the pods have developed significantly. If you can see the bulge of a developing bean through the green pod, the bean is over-mature. At this stage the pod will be too tough to eat. Harvest when plants are dry; picking beans from wet plants can spread bean bacterial blight, a disease that seriously damages the plants. Bean plants will continue to form new flowers and produce more beans if pods are continually removed before the seeds mature.
Selection and Storage
I've grown dozens of bean varieties over the years, and formed opinions along the way. My favorite bush beans are 'Major,' with plump, tender pods; 'Bush Kentucky Wonder,' with long, flattened pods; and 'Venture,' an intensely productive plant with very slim, very tender, very juicy beans. All mature in less than 60 days. Pole bean winners in my garden are 'Blue Lake,' 'Kentucky Blue,' and 'Kentucky Wonder.'
Freshly harvested beans can be stored in plastic bags in the vegetable crisper of the refrigerator for up to 3 days. Don't wash before storing or the beans will develop black spots and decay quickly. Instead, wash beans just before cooking or enjoying raw.
