What Are Pentland Javelin Potatoes?

Pentland Javelin is a first early potato variety with smooth white skin and pale flesh. It produces oval tubers with a pleasant, light flavour and a slightly waxy texture. This variety is valued for its ability to cope well with cooler soils and variable spring weather.

Pentland Javelin potatoes are best eaten fresh and are not suitable for long-term storage.

When to Plant Pentland Javelin Potatoes

In the UK, Pentland Javelin potatoes are usually planted:

• March, once the soil is workable and not waterlogged

In colder areas, planting may be delayed slightly. Chitting seed potatoes before planting helps speed up emergence and improves early growth.

How to Grow Pentland Javelin Potatoes

Soil Preparation

Pentland Javelin potatoes prefer fertile, well-drained soil. Improve 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 30 cm apart
• Leave 60 cm between rows

They also grow 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.

Watering

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

Feeding

Pentland Javelin potatoes do not require heavy feeding. A general-purpose fertiliser or organic feed at planting time is usually sufficient.

Growing Pentland Javelin Potatoes in Containers

Pentland Javelin is suitable for container growing:

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

When to Harvest Pentland Javelin Potatoes

Pentland Javelin potatoes are usually ready to harvest:

• 10–12 weeks after planting

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

How to Harvest Pentland Javelin Potatoes

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

Common Problems When Growing Pentland Javelin Potatoes

• Late frosts damaging early shoots

• Slug damage in damp conditions

This variety is often harvested before blight becomes a serious issue.
