  • 🌱 Bush Bean Seeds
  • 🌱 Pole Bean Seeds + Trellis Set
  • 🌱 Rhizobium Inoculant

Search for these at your local garden center or nursery.

Growing Tips

  • Sow seeds directly — beans don't transplant well.
  • Bush beans mature all at once (great for canning). Pole beans produce over a longer season.
  • Inoculate seeds with rhizobium bacteria for better nitrogen fixation and yield.
  • Pick beans before you can feel the seeds bulging inside the pod.
  • Don't work in the bean patch when plants are wet — spreads fungal disease.

Common Mistakes

  • Starting indoors — direct sow only, 1 inch deep after last frost.
  • Over-fertilizing with nitrogen — you'll get lush plants with few beans.
  • Letting pods mature on the vine — this signals the plant to stop producing.
  • Planting near onions or garlic — these inhibit bean growth.

Companion Planting

Companion planting improves growth, deters pests, and makes better use of garden space.
