Pole Beans

Beans are sensitive to cold temperatures and frost. They should be planted after all danger of frost is past in the spring. If the soil has warmed before the average last-frost date, an early planting may be made a week to 10 days before this date. You can assure yourself a continuous supply of snap beans by planting every 2 to 4 weeks until early August.
Plant seeds of all varieties one inch deep. Plant seeds of pole beans 4 to 6 inches apart in rows 30 to 36 inches apart along trellis, netting, fence, or poles; or in hills (four to six seeds per hill) 30 inches apart, with 30 inches between rows.
Seeds of most 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 heavy rain.
Beans have shallow roots and frequent shallow cultivation and hoeing are necessary to control small weeds and grasses. Because bean plants have fairly weak root systems, deep, close cultivation injures the plant roots, delays harvest and reduces yields.
Harvest when the pods are firm, crisp and fully elongated, but before the seed within the pod has developed significantly. Pick beans after the dew is off the plants, and they are thoroughly dry. Picking beans from wet plants can spread bean bacterial blight, a disease that seriously damages the plants. Be careful not to break the stems or branches, which are brittle on most bean varieties. The bean plant continues to form new flowers and produces more beans if pods are continually removed before the seeds mature.
