The Basics

When to plant

  • Direct seed or transplant: April–June
  • For best results, wait to direct seed until daytime temperatures are consistently above 70°F and the soil temperature is above 60°F. Direct-seeded beans will rot if the soil is too cold.

Harvest window

50–100 days depending on variety.

Care overview

  • Nitrogen fertilizer is not needed because beans are legumes that can fix nitrogen from the air.
  • For a continuous harvest of bush beans, plant successive crops 2 to 3 weeks apart.
  • Pole beans bear fruit over a longer period than bush beans, but they require trellising.
