Organic Growing Tips

  • Direct sow only — beans dislike root disturbance from transplanting.

  • Interplant with marigolds and nasturtiums to deter bean beetles and aphids.

  • Allow a few plants to go to seed at season's end to fix extra nitrogen in the soil.

  • Avoid overhead watering once flowers appear to prevent pod rot and fungal issues.
