What Are King Edward Potatoes?

King Edward is a maincrop potato variety with white skin, pink-tinged eyes, and creamy white flesh. It is a floury potato, making it especially popular for classic roast potatoes and jacket potatoes. King Edward has been grown in the UK for over a century and remains a favourite with home gardeners.

When to Plant King Edward Potatoes

In the UK, King Edward potatoes are usually planted:

• Early to mid-April, once the soil is workable and the risk of hard frost has passed

Chitting seed potatoes before planting is recommended to encourage stronger, earlier growth.

How to Grow King Edward Potatoes

Soil Preparation

King Edward potatoes grow best in fertile, well-drained soil. Improve the soil before planting by digging in well-rotted compost or organic matter to boost nutrients and drainage.

Planting Depth and Spacing

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

Good spacing helps airflow and reduces the risk of disease.

Earthing Up

As shoots appear, gradually mound soil around the stems. Continue earthing up as plants grow to protect developing tubers from light and increase yields.

Watering

Water regularly during dry periods, especially when plants are flowering and tubers are forming. Avoid waterlogging, as this can affect yield and storage quality.

Feeding

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

Growing King Edward Potatoes in Containers

King Edward can be grown in large containers:

• Use containers at least 50 cm deep
• Fill with free-draining compost
• Earth up gradually as plants grow
• Water consistently, as containers dry out quickly

Container yields may be smaller than in open ground but are still worthwhile.

When to Harvest King Edward Potatoes

King Edward potatoes are ready to harvest when:

• The foliage has completely died back
• Tubers have reached full size

This is usually late summer to early autumn, around 18–22 weeks after planting.

How to Harvest King Edward Potatoes

• Cut back foliage and wait 7–14 days to allow skins to harden
• Lift potatoes carefully with a fork
• Allow tubers to dry briefly before storing

How to Store King Edward Potatoes

• Store in a cool, dark, frost-free place
• Do not wash before storing
• Check stored potatoes regularly and remove any damaged tubers

When stored correctly, King Edward potatoes can last several months.

Common Problems When Growing King Edward Potatoes

• Blight in wet summers

• Slug damage in damp conditions

Crop rotation, good spacing, and even watering help reduce these issues.
