Can You Grow Potatoes from Kitchen Scraps?

  • Yes, but…
    While you can regrow potatoes from leftover kitchen spuds, success depends on variety, health, and what the potato was treated with.
  • Organic vs. Treated:
    Organic potatoes, or those not treated to prevent sprouting, have the best chance of success.

How to Grow Potatoes from Kitchen Spuds

  1. Choose Sprouted Potatoes:
    • Select healthy, firm potatoes with strong sprouts (“eyes”).
    • Avoid green, moldy, or shriveled spuds.
  2. Prepare for Planting:
    • If large, cut so each chunk has at least one sprout; let cut pieces dry for a day.
  3. Planting:
    • Plant in soil or a container, burying 10–15cm deep with eyes facing up.
    • Space 30cm apart or use 3–4 pieces per large pot/bag.
  4. Care:
    • Water regularly and earth up as you would with seed potatoes.
  5. Harvest:
    • Once plants flower, start checking for new potatoes.

What to Expect

  • Yield:
    Usually lower than certified seed potatoes; disease risk is higher.
  • Best for Fun/Small Crops:
    Great for kids’ projects, experiments, or growing on a windowsill or balcony.

Limitations and Warnings

  • Disease:
    Supermarket spuds can carry viruses or blight—never plant scrap potatoes in main crop beds if you’ve had disease issues before.
  • Sprout Inhibitors:
    Some grocery store potatoes may not sprout well due to chemical treatments—organics are best.

Should You Always Use Kitchen Scraps?

  • For main crops or disease-free gardens, certified seed potatoes are always safer and more reliable.
  • Use kitchen scraps for fun or small test harvests.

You can sometimes grow a new potato plant from that old, sprouting potato in your cupboard—but there are pros, cons, and a few rules to follow if you want a harvest.

Can You Use Kitchen Scraps?

  • Yes, but with caution:
    – Many store-bought potatoes are treated to stop sprouting or may carry disease.
    – Organic or untreated potatoes have the best chance of success.

How To Grow from Scraps

  1. Pick a Healthy Spud:
    – Select a potato with strong, healthy “eyes” or sprouts.
    – Avoid moldy, green, shriveled, or rotten potatoes.
  2. Prep the Potato:
    – Cut large potatoes so each piece has at least one sprout. Let cuts dry for a day.
  3. Plant:
    – Place the sprouted section in fresh compost about 10–15cm deep, with eyes facing up. – Hill up as the plant grows, just as with seed potatoes.
  4. Care:
    – Water often and feed every couple of weeks.
  5. Harvest:
    – Dig when flowering starts or foliage dies back.

What to Expect

  • Lower Yields/Risk:
    Kitchen leftovers can give a small crop, but disease and poor sprouting are more likely.
  • Best for Kids, Experiments, or Container Crops:
    Try it in pots or isolated beds—not main growing areas if your garden has had blight or other potato diseases.

Pro Tip

  • Always plant scraps in new compost or soil—never in ground where potatoes had blight, scab, or rot last year.
  • Certified seed potatoes are best for big, reliable crops.
