Preparing cut seed potatoes for planting is a simple but important step to ensure healthy plants and a strong harvest. Cutting large seed potatoes helps you stretch your planting supply and gives each plant plenty of room to develop. Here’s how to do it right.
Potatoes for cutting
Start with certified disease-free seed potatoes. Avoid using supermarket potatoes, which may carry diseases or have been treated with sprout inhibitors. Select firm, blemish-free tubers with several well-developed “eyes” (the small buds where sprouts will form).
If a seed potato is larger than a chicken egg, cut it into smaller pieces—each about 1.5 to 2 ounces. Every piece should have at least one or two strong eyes. Use a clean, sharp knife to make smooth cuts.
After cutting, let the seed pieces cure before planting. Spread them out in a single layer in a warm, well-ventilated place out of direct sunlight for 1 to 3 days. This allows the cut surfaces to form a dry, protective callus that helps prevent rot in the soil.
If your soil is cool and moist, dust the cut surfaces with garden sulfur before curing. This can reduce the risk of fungal infections.
Once cured, plant seed pieces about 4 inches deep, eyes facing upward, in loose, well-draining soil. Keep soil temperatures between 45°F and 60°F for best sprouting.
Quick Tip: Don’t cut seed potatoes too far in advance—plan to plant them within a week of cutting for best results.

Potatoes for cutting
1. Choose Healthy Seed Potatoes
Start with certified disease-free seed potatoes. Avoid using supermarket potatoes, which may carry diseases or have been treated with sprout inhibitors. Select firm, blemish-free tubers with several well-developed “eyes” (the small buds where sprouts will form).
2. Cut Large Tubers into Pieces
If a seed potato is larger than a chicken egg, cut it into smaller pieces—each about 1.5 to 2 ounces. Every piece should have at least one or two strong eyes. Use a clean, sharp knife to make smooth cuts.
3. Cure (Dry) the Cut Pieces
After cutting, let the seed pieces cure before planting. Spread them out in a single layer in a warm, well-ventilated place out of direct sunlight for 1 to 3 days. This allows the cut surfaces to form a dry, protective callus that helps prevent rot in the soil.
4. Dust with Sulfur (Optional)
If your soil is cool and moist, dust the cut surfaces with garden sulfur before curing. This can reduce the risk of fungal infections.
5. Plant in Warm, Loose Soil
Once cured, plant seed pieces about 4 inches deep, eyes facing upward, in loose, well-draining soil. Keep soil temperatures between 45°F and 60°F for best sprouting.
Quick Tip: Don’t cut seed potatoes too far in advance—plan to plant them within a week of cutting for best results.
Potato Seed Cutting Do’s and Don’ts
| Do | Why |
|---|---|
| Use certified, disease-free seed potatoes | Prevents introducing pests and diseases to your garden |
| Cut large tubers into 1.5–2 oz pieces with 1–2 eyes each | Ensures healthy sprouts and maximizes seed potato use |
| Use a clean, sharp knife | Makes smooth cuts that reduce damage and infection risk |
| Cure pieces for 1–3 days before planting | Forms a callus to prevent rot and disease |
| Store cut pieces in a warm, airy location out of sunlight | Promotes proper curing without premature sprouting |
| Plant within 7 days of cutting | Keeps seed pieces fresh and viable |
| Don’t | Why |
|---|---|
| Use supermarket potatoes | May carry disease or be treated to prevent sprouting |
| Leave pieces wet or stacked tightly | Encourages rot and mold growth |
| Cut into very small pieces with only one weak eye | Reduces plant vigor and yield |
| Plant immediately in cold, wet soil | Increases risk of decay and slow sprouting |
| Cut seed potatoes too far in advance | Causes dehydration and weak growth |
