What Are Maris Piper Potatoes?

Maris Piper is a maincrop potato variety with pale skin and cream-coloured flesh. It is prized for its high dry matter content, which makes it ideal for roasting, chips, mash, and baking. Maris Piper potatoes also store well when harvested and cured correctly.

When to Plant Maris Piper Potatoes

In the UK, Maris Piper potatoes are usually planted:

• Early to mid-April, once the soil has warmed and the risk of severe frost has passed

Chitting seed potatoes before planting is recommended to encourage strong early growth.

How to Grow Maris Piper Potatoes

Soil Preparation

Maris Piper grows best in fertile, well-drained soil. Before planting, dig in plenty of 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 35 cm apart
• Leave 75 cm between rows

This spacing allows enough room for large plants and good airflow.

Earthing Up

As shoots emerge, gradually mound soil around the stems. Continue earthing up until ridges are around 20 cm high to protect tubers from light and improve yields.

Watering

Water regularly during dry spells, particularly when plants are flowering and tubers are forming. Avoid waterlogging, as this can reduce yield and storage quality.

Feeding

Apply a balanced fertiliser at planting time. Avoid excessive nitrogen, which encourages leafy growth rather than tuber development.

Growing Maris Piper Potatoes in Containers

Maris Piper can be grown in large containers:

• Use a container at least 50 cm deep and wide
• Fill with free-draining compost
• Earth up gradually with additional compost
• Water consistently, as containers dry out quickly

Yields may be slightly lower than ground-grown plants, but results are still worthwhile.

When to Harvest Maris Piper Potatoes

Maris Piper potatoes are ready to harvest once:

• 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 Maris Piper Potatoes

• Cut back foliage and wait 7–14 days before lifting to allow skins to harden
• Lift carefully using a fork to avoid damaging tubers
• Leave potatoes to dry briefly before storing

How to Store Maris Piper Potatoes

• Store in a cool, dark, frost-free place
• Avoid washing before storage
• Check regularly and remove any damaged or rotting potatoes

Properly stored Maris Piper potatoes can last for several months.

Common Problems When Growing Maris Piper Potatoes

• Blight in wet summers
• Scab in dry or alkaline soil
• Slug damage in damp conditions

Good crop rotation, spacing, and watering practices help reduce problems.

Best Uses for Maris Piper Potatoes

Maris Piper potatoes are ideal for:

• Roasting
• Chips
• Mash
• Baking
• Wedges

They are less suited to salads due to their floury texture.
