Everything You Need to Know About German Butterball Seed Potatoes

The gourmet golden potato known for outstanding flavor, creamy texture, and impressive storage life.

German Butterball potatoes are a beloved heirloom variety prized by gardeners, homesteaders, and chefs alike. Known for their beautiful golden skin, rich buttery flavor, and firm, creamy texture, they are one of the most flavorful potato varieties you can grow.

German Butterball seed potatoes offer high yields, excellent disease resistance, and long-term storage quality, making them a top choice for both beginners and experienced growers.

Are German Butterball Potatoes Determinate or Indeterminate?

German Butterball potatoes are indeterminate (late-season) producers.

This means:

• They continue growing and producing tubers as long as the season allows
• They require and benefit from multiple rounds of hilling
• They often produce larger yields than determinate types
• They grow well in deep raised beds and tall containers
• They thrive during long warm growing seasons

Indeterminate potatoes form tubers along the expanding underground stem, making hilling essential for bigger harvests.

What Are German Butterball Seed Potatoes?

Seed potatoes are small, disease-free potato tubers specifically grown for planting.

German Butterball potatoes feature:

• Thin, lightly netted golden skin
• Deep yellow, buttery flesh
• Dense, creamy texture
• Round to slightly oval tubers
• Outstanding flavor (one of the best-tasting varieties)
• Excellent storage life
• Vigorous, indeterminate growth habit
• Late-season maturity

This heirloom variety has even been recognized as a winner of the Slow Food “Ark of Taste”, thanks to its exceptional culinary reputation.

When to Plant German Butterball Seed Potatoes

Plant when:

• Soil temperature reaches 50–60°F
• 2–4 weeks before your last expected frost
• Soil is loose, dry enough to work, and well drained

Because they are indeterminate and late-season, early planting allows them the longest development time.

How to Prepare and Plant German Butterball Seed Potatoes

1. Cutting & Curing

• Cut large seed potatoes into 1–2-inch chunks
• Ensure each piece has at least one eye
• Allow to dry and callous for 24–48 hours

2. Soil Preparation

German Butterball potatoes thrive in:

• Loose, loamy, fertile soil
• pH of 5.0–6.5
• Raised beds, trenches, or deep containers

Work compost or aged manure into the soil before planting.

3. Planting

• Dig trenches 6–8 inches deep
• Place seed pieces eyes-up
• Space pieces 12 inches apart
• Space rows 36–42 inches apart
• Cover with 3–4 inches of soil, leaving room for future hilling

Season-Long Care for German Butterball Potatoes

✔ Hilling (Very Important!)

Because German Butterball potatoes are indeterminate:

• Begin hilling at 6–8 inches tall
• Pull soil up around stems, covering halfway up
• Repeat every 1–2 weeks
• Continue until hills are 10–12 inches tall

This encourages more tuber production and prevents sunburned (green) potatoes.

✔ Watering

• Maintain consistent moisture
• Aim for 1–2 inches of water weekly
• Do not over water—soggy soil leads to rot

Watering is critical during flowering, when tubers set.

✔ Fertilizing

• Use a low-nitrogen, high-phosphorus fertilizer
• Too much nitrogen = leaves grow, potatoes don’t
• Add compost or organic fertilizer mid-season

✔ Mulching

Mulch helps:

• Retain moisture
• Control weeds
• Keep soil cool
• Improve tuber quality

✔ Pest & Disease Management

Watch for:

• Colorado potato beetles
• Aphids
• Flea beetles
• Wire-worms

Rotate crops yearly and remove infected plants promptly to prevent spread.

Harvesting German Butterball Potatoes

New Potatoes

• Ready in 70–90 days
• Harvest when plants bloom

Full-Size Mature Potatoes

• Usually ready 100–130 days (late-season)
• Harvest once vines yellow and die back naturally

How to Harvest

1. Use a fork to gently loosen soil
2. Lift tubers carefully to avoid scarring
3. Move potatoes into shade to dry a few hours
4. Keep out of direct sunlight to avoid greening

Indeterminate types often produce more if left in the ground longer.

Curing & Storing German Butterball Potatoes

Curing

Cure potatoes for 10–14 days in:

• A dark location
• 55–65°F
• Good airflow

This toughens the skin for long-term storage.

Storage Conditions

• Temperature: 40–50°F
• Humid, dark environment
• Never refrigerate (cold turns starch into sugar)
• Keep away from onions (they cause sprouting)

German Butterballs store exceptionally well—often lasting 5+ months when stored correctly.
