The Basics

When to plant

  • Direct seed or transplant: April–June
  • For best results, wait to direct seed until daytime temperatures are regularly over 70 degrees and soil temperature is over 60 degrees. 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 over a longer period than bush beans but require trellising.
