Regrowing Potatoes from Kitchen Scraps: Does It Work?

Ever noticed a potato sprouting on the kitchen shelf and wondered if you could grow more from it? It’s possible—and fun! Here’s how to turn kitchen scraps into a potato crop, plus important things to consider.

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.
