What Are Cara Potatoes?

Cara is a maincrop potato variety with pale skin and white flesh. It has a slightly waxy to floury texture, making it suitable for boiling, roasting, mashing, and baking. Cara is widely grown on allotments and in gardens because it performs well even in challenging conditions.

Why Is Cara Considered Blight-Resistant?

Cara potatoes were bred with natural resistance to late blight, one of the most serious potato diseases in the UK. While no potato is completely immune, Cara has a strong ability to slow the spread of blight, particularly on foliage.

This resistance means:

  • Foliage stays green and healthy for longer
  • Tubers are better protected underground
  • Crops are more likely to reach maturity before blight causes serious damage

Cara is especially useful in wet summers, where blight can spread quickly across gardens and allotments.

How Blight Resistance Benefits Gardeners

Growing Cara potatoes can:

  • Reduce the risk of crop failure
  • Limit the need for sprays or treatments
  • Allow later harvesting compared to less resistant varieties
  • Make potato growing easier for beginners

This makes Cara a strong choice for organic and low-input growing.

How to Grow Cara Potatoes Successfully

When to Plant

Cara potatoes are usually planted:

  • Early to mid-April, once soil conditions improve

Chitting seed potatoes before planting encourages stronger early growth.

Soil and Planting

  • Plant seed potatoes 10–15 cm deep
  • Space plants 35 cm apart
  • Leave 75 cm between rows

Cara performs particularly well in heavier or moisture-retentive soils compared to many other varieties.

Earthing Up

Earth up plants regularly as shoots grow to protect tubers from light and increase yields.

Watering

Water during dry spells, especially when tubers are forming. Cara tolerates wet soil better than many varieties but still benefits from balanced moisture.

When to Harvest Cara Potatoes

Cara potatoes are ready to harvest:

  • Late summer to early autumn, once foliage has died back

Thanks to their blight resistance, Cara plants often remain healthy longer into the season, allowing tubers to fully mature.

How to Store Cara Potatoes

Cara potatoes store well when cured and handled correctly:

  • Allow skins to toughen after lifting
  • Store in a cool, dark, frost-free place
  • Avoid washing before storage

Stored correctly, Cara potatoes can last for several months.

Best Uses for Cara Potatoes

Cara potatoes are suitable for:

  • Boiling
  • Roasting
  • Mash
  • Baking
  • Wedges

Their all-round texture makes them a versatile kitchen potato.

Limitations of Cara Potatoes

While Cara has good blight resistance:

  • It is not completely immune
  • Very wet, prolonged conditions can still cause problems
  • Good spacing and airflow are still important

Combining Cara with other blight-resistant varieties improves overall crop reliability.

Why Grow Cara Potatoes?

  • Strong resistance to late blight
  • Reliable yields in UK conditions
  • Suitable for wetter soils
  • Easy to grow for beginners and experienced gardeners

Growing Tips for Best Results

  • Rotate crops yearly to reduce disease pressure
  • Remove infected foliage promptly if blight appears nearby
  • Avoid overcrowding plants
  • Harvest only when soil conditions are suitable
