All beans, except Lima, are relatively easy to grow in New England. Beans should be planted in well-drained soil to reduce the chances of disease, and should not be repeatedly planted in the same field (rotate every 2 to 3 years) because of soil-borne diseases.
Planting should commence only when soil temperatures have reached 60°F. Optimum seed germination occurs at soil temperatures above 70°F. Irrigation may be necessary at time of bloom in order to insure maximum pod set under dry soil conditions. Temperatures above 90°F or below 50°F cause poor pod set.
Types and Varieties
Snap beans can have yellow (wax), purple or green pods, and grow in bush or vine/pole forms. Pods are flat (Italian types), oval, or round, depending on cultivar. Filet beans have slender stringless pods that stay small and thin. Good commercial yields for fresh market are 200 bushels or more per acre.
In recent years, a significant acreage of pea beans and a small, but important, acreage of light red kidney varieties have been grown in northern New England. A good yield is 1,300 lb/A, but 2,200 to 2,500 lb/A is possible.
Lima beans are of minor importance in most areas in New England. Seed germination requires warm soil. The need to plant late and the days to maturity of available varieties sharply reduce length of the harvest season and restrict production in northern New England. A good yield of shelled lima beans is 3,000 lb/A.

Apply lime according to soil test to maintain soil pH at 6.5 to 6.8.
Apply no more than 80 to 100 lb/A combined weight of nitrogen and potash through the planter.
A sidedressing of 30 lb nitrogen/A at prebloom may extend harvest period and increase yields, especially on sandy soils.
Machine harvested beans are unlikely to need sidedressing.

Bush Snap Beans: Plants should be spaced 1.5" to 2" within rows and 18" to 36" between rows. Use the higher plant population under a more favorable environment. Sow 75 to 100 lb of seed/A (approximately 0.5 lb/100' of row) depending on seed type and percent germination. Plant seed 1" to 2" deep, depending on soil type and/or soil moisture content. Repeat seeding every 2 to 3 weeks for a continuous supply.
Pole Beans: Pole beans can be supported by a bean trellis of a large mesh nylon material or large mesh wire fence. Removing the plants from the fence is a chore, however. Economics will allow disposal of the nylon mesh. The traditional manner is to use a 4 pole tepee method. When using the trellis or fence method, plant seeds 1" to 2" deep, 6" apart, in rows 4' apart. For the tepee method, plant 6 to 7 seeds around each pole. One lb of seed will plant 240' of row or around 150 poles.
Lima Beans: Plants should be spaced 2" to 4" within rows and 18" to 36" between rows. Use 40 to 60 lb seed/A (4 to 6 oz/100' of row). Plant 1" deep in moist heavy soils and 2" in dry, sandy soils.
Dry Beans: Plants should be spaced 2" to 3" within rows and 28" to 36" between rows. Rate of seeding depends on seed size, percent germination, time of planting, and row spacing (check seed company recommendations for each cultivar). Plant seed 1" to 2" deep depending on soil type and/or soil moisture content.
Defoliation of Dry Beans
paraquat (Gramoxone Inteon 3S*): Apply 0.75 to 1.3 pt/A (7 dh, REI 48h, Group 22) in 20 gal water with ground equipment or in a minimum of 5 gal water with aerial equipment. Add spreader (nonionic) at 1 qt per 100 gal spray mix. For vining-type beans or bush-type with lush growth, use a single application of the higher rate. May also be applied as a split application. Do not make more than two applications or exceed a total of 1.5 pts/A. The split application method may improve vine coverage. Apply when the crop is mature and at least 80% of the pods are yellowing and mostly ripe with no more than 40% (bush type) or 30% (vine type) of the leaves still green in color. Do not apply when weather conditions favor spray drift. A drift control agent may be included to reduce spray drift. Do not use on Fava beans.
sodium chlorate (Defol 6): 1 gal/A (7 dh, REI 48h). Apply in 5 to 10 gal water by air or 10 to 20 gal by ground equipment. Thorough coverage is essential. Make application 7 to 10 days before anticipated harvest, longer if temperatures are cool. Do not graze treated fields or feed treated fodder to livestock.
Snap beans: Average snap bean yields are 4,000 lb/A (80 lb/100' of row) for bush and 2,500 lb/A (50 lb/100' of row) for pole. Hand-picked snap beans are in demand. Piece rate or share picking (1:1) is suggested for payment. This can increase picker efficiency. Large scale growers should investigate mechanical harvesters. Beans should be harvested when the pod is bright green and fleshy, and the seeds are small and green. Pods should snap easily when bent. Optimum storage conditions are 41-45° F at 95-100% relative humidity, but storage time is limited. After >10% weight loss, beans will not be marketable.
Dry beans: Good dry bean yields range from 1500 to 1800 lbs. per acre. Dry beans should not be harvested until the majority of pods have turned yellow and thoroughly matured, but before the pods dry to the point of shatter. The mature beans should be so hard that you cannot easily bite into the seed. Mechanized harvesting can be done with a puller-cutter, which will uproot or cut the entire plant and lay it on the ground in windrows as the machine moves along the field. Windrows can be combined when beans have dried to 18% moisture. Once shelled, beans should be conditioned using a low temperature and dried to a moisture level of 15 to 16%, then stored in rodent and insect proof bins at temperature ranging from 35 to 55° F.
