What Are Casablanca Potatoes?

Casablanca is a first early potato variety with white skin and white flesh. The tubers are oval and uniform, with a slightly waxy texture that makes them ideal for boiling and salads. Casablanca potatoes are valued for their clean skins, good yields, and ability to perform well in cooler spring conditions.

They are best eaten fresh and are not intended for long-term storage.

When to Plant Casablanca Potatoes

In the UK, Casablanca potatoes are usually planted:

• Late February to March, depending on soil conditions

Plant once the soil is workable and not waterlogged. Chitting seed potatoes before planting helps speed up growth and encourages earlier harvesting.

How to Grow Casablanca Potatoes

Soil Preparation

Casablanca potatoes grow best in fertile, well-drained soil. Before planting, dig in well-rotted compost or organic matter to improve soil structure and nutrient levels.

Planting Depth and Spacing

• Plant seed potatoes 10–15 cm deep
• Space plants 30 cm apart
• Leave 60 cm between rows

Casablanca also grows very well in containers and grow bags.

Earthing Up

As shoots appear, earth up soil around the stems to protect them from late frosts. Continue earthing up as plants grow to keep developing tubers covered and encourage better yields.

Watering

Water regularly during dry spells, especially once plants begin flowering. Avoid waterlogging, as early potatoes dislike overly wet soil.

Feeding

Casablanca potatoes do not need heavy feeding. A balanced fertiliser or organic feed at planting time is usually sufficient.

Growing Casablanca Potatoes in Containers

Casablanca is an excellent variety for container growing:

• Use containers at least 40 cm deep
• Fill with free-draining compost
• Earth up gradually with additional compost
• Water consistently, as containers dry out faster than garden soil

When to Harvest Casablanca Potatoes

Casablanca potatoes are usually ready to harvest:

• 9–11 weeks after planting

Harvest when plants are flowering and tubers are small to medium-sized with thin skins.

How to Harvest Casablanca Potatoes

• Gently loosen soil with a fork
• Lift carefully to avoid damaging delicate skins
• Harvest as needed rather than lifting the whole crop at once

Casablanca potatoes are best enjoyed immediately after harvesting.

Common Problems When Growing Casablanca Potatoes

• Frost damage to early shoots
• Dry soil reducing tuber size
• Slug damage in damp conditions

Casablanca is typically harvested before blight becomes a serious issue.

Best Uses for Casablanca Potatoes

Casablanca potatoes are ideal for:

• Boiling
• Steaming
• Salads
• New potatoes with butter and herbs

They are not suitable for mash, roasting, or long-term storage.
