Why Cut Seed Potatoes?

Cutting seed potatoes allows you to:

• Increase the number of plants from larger tubers
• Save money on seed potatoes
• Space plants more evenly
• Use oversized seed potatoes more efficiently

This method works best with healthy, certified seed potatoes.

When Cutting Seed Potatoes Is Suitable

Cut seed potatoes only if:

• The potato is large, firm, and healthy
• It has several strong “eyes”
• Conditions are not cold or waterlogged
• You can allow cut surfaces to dry before planting

Small seed potatoes are best planted whole.

How to Cut Seed Potatoes Correctly

To reduce the risk of problems, follow these steps:

• Use a clean, sharp knife
• Cut potatoes so each piece has at least one or two healthy eyes
• Avoid tiny pieces — larger sections establish better
• Leave cut pieces in a cool, airy place for 24–48 hours
• Allow cut surfaces to dry and form a protective skin

This drying process helps prevent rotting in the soil.

Planting Cut Seed Potatoes

Once the cut pieces have dried:

• Plant with the eyes facing upwards
• Use well-drained soil
• Avoid planting into cold, wet ground
• Earth up as shoots appear to protect from frost

Good drainage is especially important for cut seed potatoes.

Risks of Planting Cut Seed Potatoes

While effective, cutting does increase risk slightly:

• Greater chance of rot in wet or cold soil
• Higher disease risk if tools or potatoes aren’t clean
• Slower early growth in poor conditions

These risks are minimal when soil conditions are right.

Cut vs Whole Seed Potatoes

• Whole seed potatoes: Lower risk, best for early planting
• Cut seed potatoes: More economical, best for later plantings

For early crops, whole tubers are often safer.

Final Thoughts

Planting cut seed potatoes is perfectly acceptable and widely used, provided it’s done carefully. Always use certified seed potatoes, allow cut surfaces to dry properly, and plant into suitable soil conditions. When done correctly, cut seed potatoes grow just as well as whole ones and produce excellent crops.
