What Are Wilja Potatoes?

Wilja is a second early potato variety with smooth yellow skin and pale yellow flesh. It has a slightly waxy to floury texture, which means it holds together well when boiled but also works for roasting and light mashing. Wilja is especially well known for its flavour, often considered one of the tastiest early potatoes.

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

When to Plant Wilja Potatoes

In the UK, Wilja potatoes are usually planted:

• Late March to early April, once the soil is workable and not waterlogged

Chitting seed potatoes before planting is recommended to encourage faster emergence and stronger plants.

How to Grow Wilja Potatoes

Soil Preparation

Wilja potatoes prefer 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 60–65 cm between rows

Wilja also grows well in raised beds and large containers.

Earthing Up

As shoots emerge, gradually earth up soil around the stems. This protects developing tubers from light and helps improve yields.

Watering

Water regularly during dry spells, especially during flowering and tuber formation. Avoid waterlogging, as Wilja potatoes dislike very wet soil.

Feeding

Apply a balanced fertiliser at planting time. Avoid excessive nitrogen, which can encourage leafy growth at the expense of tuber development.

Growing Wilja Potatoes in Containers

Wilja potatoes are suitable for container growing:

• Use containers at least 40–45 cm deep
• Fill with free-draining compost
• Earth up gradually as plants grow
• Water consistently, as containers dry out quickly

When to Harvest Wilja Potatoes

Wilja potatoes are usually ready to harvest:

• 13–15 weeks after planting

Harvest when plants are flowering or just after flowering finishes. Tubers should be medium-sized with thin skins.

How to Harvest Wilja Potatoes

• Loosen soil carefully with a fork
• Lift gently to avoid damaging skins
• Harvest as needed rather than lifting the entire crop at once

Wilja potatoes are best eaten soon after harvesting.

Common Problems When Growing Wilja Potatoes

• Dry soil reducing tuber size
• Slug damage in damp conditions
• Blight risk is lower due to early harvest but still possible in wet summers

Good spacing and airflow help reduce disease risk.

Best Uses for Wilja Potatoes

Wilja potatoes are ideal for:

• Boiling
• Steaming
• Roasting
• Wedges
• Light mashing

They are less suitable for long-term storage or heavy chipping.
