Common Potato Problems

What to watch for — and how to fix it before it spreads.

🐛

Pests

Colorado Potato Beetle

Yellow-and-black striped adults and orange larvae devour foliage; can completely defoliate a plant.

Fix:

Handpick adults and orange egg masses daily; apply spinosad; rotate crops and till after harvest.

Aphids (Potato Aphid)

Green or pink colonies on undersides of leaves; transmit potato virus Y and leafroll virus.

Fix:

Spray with insecticidal soap; use reflective mulch; control ants that farm aphids.

Wireworm

Soil larvae bore small round holes through tubers; worst in recently tilled sod ground.

Fix:

Avoid recently grassed areas; use mustard seed meal in soil; beneficial nematodes.

🍂

Diseases

Late Blight (Phytophthora infestans)

The pathogen behind the Irish Famine — rapidly destroys foliage and tubers in cool, wet weather.

Fix:

Plant resistant varieties; apply copper fungicide preventively; destroy infected plants immediately; never compost.

Common Scab

Rough, corky patches on tuber skin; cosmetic but annoying; thrives in alkaline soils.

Fix:

Lower soil pH below 5.5 for potato beds; water consistently after tuber initiation; plant resistant varieties.

Verticillium Wilt

Soil-borne fungus causing early die-back and yellowing; stunts tuber development.

Fix:

Rotate crops (4+ year rotation); improve drainage; use certified disease-free seed potatoes.

💡

Common Mistakes

Planting store-bought potatoes

Grocery store potatoes are often treated with sprout inhibitors and may carry disease.

Fix:

Use certified seed potatoes from a reputable supplier; they're disease-free and guaranteed to sprout.

Not hilling

Exposed tubers turn green (solanine-toxic) and sunburn.

Fix:

Hill soil up around stems every 2 weeks as vines grow, keeping tubers buried under 4–6 inches of soil.

Watering overhead near harvest

Wet foliage with tubers near full size promotes late blight and storage rots.

Fix:

Switch to drip irrigation in late season; stop all watering 2 weeks before planned harvest.

🌾 Seed Saving Guide

🪴 Vegetative propagation

Propagate vegetatively, not by seed

Potatoes are propagated by planting whole small tubers or cut pieces of tuber with growth "eyes."

Save egg-sized tubers from your harvest for seed potatoes. Store in a cool, dark, humid place over winter.
