Lightly mist the dry soil with a garden hose or watering can. As these vegetables grow from seeds to seedlings, their water requirements will change. Pole beans require little care, except regular weeding and supplemental watering in dry weather. Bean plants need about an inch of water per week. Water plants in the morning to allow foliage time to dry out before night falls.
As the pole beans grow, periodically weave stray vines around the poles of the teepee. This trains plants to grow upward, not outward.
