Step by step

  1. Prepare the bed: loosen the soil and mix in an inch or two of compost.
  2. Plant seeds May 15 – Jun 19, 1 inch deep, 4 to 6 inches apart along a trellis.
  3. Keep the soil evenly moist until sprouts appear, which can take one to three weeks in cool soil.
  4. Harvest: Pick when pods are pencil-thick and before the seeds bulge. Picking every few days keeps the vines producing.
