What Is Potato Blight?
Late blight is a fungal disease caused by Phytophthora infestans. It rapidly destroys foliage and tubers in warm, wet conditions, often spreading quickly across crops. Blight-resistant varieties can slow or reduce the impact of the disease, giving gardeners a better chance of harvesting good yields.
How Blight Resistance Works
Blight-resistant potatoes are bred to naturally withstand or slow the progress of blight, reducing leaf damage and protecting tubers. They’re not immune, but resistance often means you won’t lose your entire crop when blight arrives.
Best Blight-Resistant Potato Varieties (UK)
Sarpo Mira
A standout variety with strong blight resistance and heavy yields. Sarpo Mira produces robust plants and tubers ideal for boiling, roasting, and storing. It’s one of the most trusted choices for organic and low-spray gardeners.

Known for its reliable blight resistance and adaptability to wetter UK climates. Cara is a versatile maincrop potato that yields well and stores reasonably.
Carolus
A dependable maincrop potato with good natural resistance to late blight. Carolus delivers solid yields and good all-round cooking quality.
Setanta
A blight-resistant variety that performs well in UK conditions. Setanta produces evenly sized tubers and holds up well against disease pressure.
Santé
Another strong choice for blight resistance, Santé is a maincrop potato that combines good yields with excellent resistance. Its tubers are versatile for many cooking methods.
Teima
Teima has good resistance to late blight and is often chosen by growers aiming to minimise disease risk without sacrificing yield or flavour.
Growing Tips for Blight-Resistant Potatoes
Even with resistant varieties, good growing practices help protect crops:
Plant in Well-Drained Soil
Blight thrives in damp conditions. Ensure soil drains well to reduce disease risk.
Space Plants Well
Good airflow between rows and plants helps foliage dry faster after rain, reducing blight spread.
Remove Infected Leaves
If you see blight spots on leaves, remove and destroy affected foliage promptly to slow disease progression.
Rotate Crops
Avoid planting potatoes or tomatoes in the same spot year after year — this helps reduce soil-borne disease build-up.
When to Harvest Blight-Resistant Potatoes
Blight-resistant varieties can often be harvested later in the season when other crops succumb to disease. Harvest once foliage has died back naturally and tubers are fully mature.
Why Grow Blight-Resistant Varieties?
- Reduced need for fungicide sprays
- Better chance of healthy yields in wet weather
- Suitable for organic and low-input gardens
- Longer growing window in UK conditions
Choosing the Right Blight-Resistant Potatoes
Growing two or more resistant varieties helps spread harvests and increases your chances of success across variable UK weather patterns.
