How to Grow Pole Beans Inside

By Sarah Terry ; Updated September 21, 2017

Pole beans (Phaseolus vulgaris) are annual vegetables that conserve space by growing upright on poles, trellises or teepees, instead of creeping across the ground. Pole beans produce crops over a longer time period in summer. These are low-maintenance vegetables that require only support for climbing and regular watering.

You don’t need to fertilize pole beans because, like other legumes, pole beans actually enrich the soil with nitrogen instead of absorbing it. You can grow pole beans indoors, as long as you can provide enough sunlight for the plants.

Fill a large trough that has drainage holes in the bottom with all-purpose potting soil. The trough planter should be at least 18 inches tall, 2 to 3 feet wide and as long as needed for the number of pole bean plants you’re growing, spaced 6 to 9 inches apart.

Plant your pole bean seeds about 1 inch deep into the soil and spaced 6 to 9 inches apart. Water the seeds evenly and lightly each day until they germinate and begin to sprout.

Place the trough planter in a bright, sunny spot where air temperatures are 70 to 80 degrees Fahrenheit, ensuring that the potting soil stays above 60 degrees. Set the planter outdoors in full sunlight during the daytime, if possible.

Insert poles, canes or teepees in the planter, or erect a trellis beside the trough, to provide a support on which the pole beans can grow. Set up the supports when the pole bean seedlings have about two to four leaves, ensuring that each plant has a support.

Water your pole beans two or three times each week to keep the soil evenly moistened down to the roots. Water the pole beans more frequently during dry or hot conditions.

 

Things You Will Need

  • Trough planter
  • All-purpose potting soil
  • Pole bean seeds
  • Watering can
  • Trellis, poles, canes or teepees

Tip

  • Select a rich potting soil that has an average pH of 6.0 to 7.5. Ensure that your planter trough is plenty deep enough to accommodate the pole bean plants' roots.

Warning

  • The biggest challenge for growing pole beans inside is providing the plants with enough sunlight, because they require full, direct sun. If you can't set the pole bean plants outdoors during the daytime, you may need to use grow lights to supplement the plants' light needs.
