Growing Tips

  • Cut seed potatoes into pieces with 2–3 eyes each. Let cut surfaces dry 24 hours before planting.
  • Hill soil around plants as they grow — exposed tubers turn green and toxic.
  • Water deeply and consistently, especially after flowers appear.
  • Stop watering 2 weeks before harvest to toughen skins for storage.
  • Let vines die back naturally before harvesting for best storage quality.

Common Mistakes

  • Using grocery store potatoes — they may be treated to prevent sprouting.
  • Not hilling — green potatoes contain solanine and should not be eaten.
  • Harvesting too early — wait until vines die back for proper curing.
  • Planting in the same spot — rotate every 3–4 years to prevent scab and blight.

Companion Planting
