Selecting Seed Potatoes for Top Results

Great potatoes start with great seed! Healthy, high-quality “seed potatoes” ensure strong plants, big yields, and reduced risk of disease. But with so many options on the racks—or online—how do you pick the best?

Here’s your go-to guide for choosing seed potatoes that’ll set you up for spud success.

What Are Seed Potatoes?

• “Seed potatoes” are just small, specially grown potato tubers.
• They aren’t true seeds!
• Certified seed potatoes are guaranteed to be disease-free and grown to high standards, unlike supermarket or leftover kitchen potatoes.

Why Not Use Supermarket Potatoes?

• Store-bought spuds are often treated with chemicals to prevent sprouting.
• They may harbor hidden diseases like blight, virus, or scab.
• Using supermarket potatoes can introduce pests that ruin your soil for years.

Always buy certified seed potatoes from a trusted nursery or garden center.

How to Choose Quality Seed Potatoes

1. Inspect Each Tuber:
   • Should be firm, plump, and free of soft spots.
   • Watch for cuts, mold, shriveled areas, or green patches (a sign of sun exposure).
   • Size: Large tubers can be cut into pieces (each with at least one “eye”); small, egg-sized potatoes can be planted whole.
2. Variety Matters:
   • Match your garden’s conditions and your favorite recipes:
     • Early types for impatient gardeners or containers
     • Maincrops for big yields and long storage
     • Culinary traits (see previous article)
3. Certified Label:
   • Look for “certified seed potato” labels or supplier assurances, especially if buying online.

How Many Seed Potatoes Do You Need?

• 1kg (about 2.2 lbs) of seed potatoes typically plants a 3–4m row (10–12 feet), and yields 10–15kg (22–33 lbs) of spuds.
• For grow bags: 3–5 tubers per standard bag (around 40 liters).

Should You Cut Large Seed Potatoes?

• If your seed potatoes are big, you can cut them into pieces, each with one or two “eyes” (small sprouts).
• Let the cut surfaces dry for a day before planting to reduce rot risk.
• Do not cut if there are no obvious eyes!

Ordering Online vs. Local:

• Buying locally lets you choose each potato and often means varieties suited for your area.
• Ordering online offers a greater selection, but purchase early—many favorites sell out fast!

Pro Tips:

• Store seed potatoes in a cool, light place (not dark) before planting so they begin to sprout (“chit”).
• If you missed delivery or your garden center is out, ask neighbors or local gardening groups for swap shares!
