When to Plant Green Beans in North Carolina

Last reviewed by GardenSproutly against the sources listed on this page.

Snap beans, also called green beans, are a warm-season crop. Like other warm-season vegetables, they generally go in the ground after the last frost date.[1]

Bush beans are compact and need no support. Pole beans climb and need a trellis, which makes good use of vertical space.[2]

How to plant
Direct seed in the garden[3],[4],[5]
Days to harvest
Bush: 50–55 days. Pole: 65–70 days[4]
Spacing
Bush 2 in.; pole 6 in.[4]
Soil temperature
At least 60°F for seed germination[6]

Timing your plantings

Wait for warm soil. Beans need a soil temperature of at least 60°F to germinate. Henderson County Extension recommends judging soil temperature by a 3-day average.[6]

In western North Carolina, beans are an exception to the general advice to plant early, because they are susceptible to stem rot in cold weather.[5]

The eastern and central calendars list a long run of sowing dates for bush and pole beans, with spring and late-summer plantings.[3],[4]

Sowing bean seed

  • Choose full sun and fertile, well-drained soil.[2]
  • If the soil is dry at planting, water it 4 to 6 inches deep and let the surface dry before seeding.[1]
  • Plant beans by drilling: space seeds evenly down the row, a little closer than the final spacing, and thin extra plants after they come up.[1]
  • In spring and summer, plant seeds 1 to 2 times as deep as their widest diameter. In fall, plant them 1½ to 2 times deeper than that.[1]
  • Plant again every few weeks within the recommended window to spread out your harvest.[4]

Harvesting snap beans

Start picking before the seeds develop inside the pods, when pods are about as thick as a pencil. Beans are ready if they snap easily when bent in half.[1]

Pick regularly while pods are young and tender to keep plants producing.[2]

Beans and soil health

Beans add nitrogen back to the soil and form a beneficial relationship with soil fungi that improves their uptake of water and nutrients.[2]
