Everything You Need to Know About French Fingerling Seed Potatoes

The gourmet, rosy-skinned fingerling with exceptional flavor and dependable performance.

French Fingerling Seed Potatoes are one of the most beloved specialty potato varieties among chefs, home gardeners, and market growers. Known for their rose-pink skin, yellow flesh, and occasional pink marbling, they offer outstanding flavor and impressive versatility. Their long, slender fingerling shape makes them ideal for roasting, salads, and gourmet plating.

These seed potatoes produce highly reliable yields and thrive in a wide range of growing conditions — making them a favorite for gardeners who want a unique and flavorful addition to their potato patch.

Are French Fingerling Potatoes Determinate or Indeterminate?

French Fingerling potatoes are indeterminate.

This means they:

• Continue growing and producing tubers throughout the season
• Benefit from regular hilling to create more room for developing potatoes
• Can be grown in deep raised beds, trenches, or tall containers
• Often yield more potatoes than determinate varieties when properly hilled
• Allow for harvesting some early “new potatoes” while leaving the rest to mature

Indeterminate varieties like French Fingerling grow longer vines and appreciate deeper soil for extended tuber development.

How to Plant French Fingerling Seed Potatoes

1. Soil Preparation

French Fingerlings thrive in:

• Well-drained, loose, loamy soil
• pH 5.0–6.5
• Soil enriched with compost or aged manure

Avoid heavy clay or waterlogged soils, which hinder tuber formation.

2. Cutting & Curing

If seed potatoes are large:

• Cut into 1–2" pieces with at least one eye per piece
• Let pieces cure and callous for 24–48 hours
• Small fingerling-sized seed potatoes should be planted whole for best results

3. Planting

• Plant 2–4 weeks before last frost or when soil reaches 45–55°F
• Dig trenches 6–8 inches deep
• Space pieces 10–12 inches apart
• Space rows 30–36 inches apart
• Cover with 3–4 inches of soil at first

French Fingerlings sprout a bit slower than some varieties — don’t worry, this is normal.

Season-Long Care

Hilling

Because this is an indeterminate variety, hilling is essential.

• Hill when plants reach 6–8 inches
• Pull soil around stems until only a few inches of foliage remain visible
• Repeat every 1–2 weeks
• Finish with hills 10–12 inches tall

Hilling boosts yields and prevents green potatoes.

Watering

• Maintain even moisture
• 1–2 inches of water weekly
• Avoid overwatering (can lead to rot or scab)
• Mulch helps retain moisture and deter weeds

Fertilizing

• Use a balanced fertilizer (not high nitrogen)
• Too much nitrogen = lush foliage, fewer potatoes
• Add compost mid-season for best results

Pest & Disease Prevention

Watch for:

• Colorado potato beetles
• Aphids
• Wireworms
• Flea beetles

Rotate crops yearly to avoid soil-borne diseases like early blight, late blight, or scab.

French Fingerlings are known to tolerate imperfect soils better than some gourmet varieties.

Harvesting French Fingerling Potatoes

For New Potatoes

• Harvest in 70–80 days
• Dig gently and remove only what you need
• Leave the rest to size up

For Full-Sized Fingerlings

• Harvest in 90–110 days
• Wait until vines start to yellow and die back
• Loosen soil with a fork and lift carefully (fingerlings bruise easily)

Handle gently — their thin skins are more delicate before curing.

Curing & Storage

Curing

• Cure in a shaded, dry, well-ventilated place for 1–2 weeks
• Skin toughens, flavor deepens

Storage

• Ideal temps: 40–50°F
• Keep dark to prevent greening
• Good humidity improves storage life
• Do not refrigerate (sweetens potatoes unnaturally)

French Fingerlings store surprisingly well for a gourmet variety.

Culinary Uses for French Fingerling Potatoes

French Fingerlings are prized for their firm, creamy texture that never gets mushy.

Perfect for:

• Roasting
• Pan-frying
• Potato salads
• Sautéing
• Grilling
• Boiling
• Baking in skillets
• Oven sheet-pan meals

Their color and shape make them a gourmet favorite in restaurant kitchens.
