WILJA POTATO

By David Marks
An excellent choice of potato not only because it it extremely versatile but primarily because of taste. Wilja tastes of real potato and takes on some of the characteristics of the soil in which it is grown. As you might guess, the supermarkets didn’t like the idea of a potato tasting like a potato so they dumped Wilja several years ago in favour of the blander Estima.For amateur gardeners interested in a second early that is full of flavour and suffers from no major drawbacks then we recommend Wilja very highly.

PARENTAGE

The parents of Wilja are Climax x KO 51-123

APPEARANCE, TASTE AND CHARACTERISTICS OF WILJA

The Wilja potato

The yield from Wilja is good, not astonishing but very acceptable. What is unusual about this variety is that the majority of potatoes produced reach full size with only very small differences between them. The flesh is of a medium dry texture making this an excellent all round potato for roast, boiling, jackets and chips. One of Wilja’s enduring advantages over some potatoes is that it holds its shape well even when boiled for a couple of minutes longer than necessary.

POSITIVE POINTS FOR WILJA
An excellent all-rounder as far as cooking is concerned and makes the best boiled potatoes. It’s tops for taste. For a second early it keeps well. Excellent resistance to scab and dry rot, no real failings as far as disease resistance is concerned except for eelworm (potato cyst nematode). Good resistance to slugs.

NEGATIVE POINTS FOR WILJA
There are no major drawbacks to Wilja except for a susceptibility to eelworm. It was dropped from the supermarkets in favour of Estima because of its slightly rough skin. The last time you ate the skin of a second early potato was ………?

Seed potatoes of this variety are available online, in many garden centres and also some of the diy stores. They are also sold by some of the discount supermarkets at low prices – most years they appear in Lidl, Aldi, Wilkinsons and even Poundland from the middle of February.

WHEN TO CHIT / SPROUT WILJA POTATOES

We recommend that you start chitting / sprouting Wilja potatoes in. the third week of February This will give them four to five weeks to develop healthy sprouts just at the time when they are ready to be planted out. Keep the potatoes in cool but light conditions to ensure they grow short, green sprouts. Click here for our page dedicated to chitting / sprouting potatoes in the UK and Ireland.

WHEN TO PLANT WILJA POTATOES

Wilja potatoes are second earlies potatoes and they are ready for harvest, if conditions are correct, 15 to 17 weeks after the seed potatoes are planted. The key factor governing the time for planting all potatoes is the date of the last frost in your area. Even a touch of frost can damage potato plants if their foliage is above ground, an unexpected severe frost can kill them completely.

The date for planting Wilja seed potatoes can be calculated on the basis that seed potatoes will take four weeks before they appear above ground. Given also that you want them to appear above ground only when the danger of frost has passed (the last week of April is the UK average ) the last week of March is about right time to plant them.

WHEN TO HARVEST WILJA POTATOES

The harvest date for all potatoes is not only dependent on when you plant your seed potatoes, it also depends on the weather conditions throughout the growing season. But on average you can expect your Wilja potatoes to be ready for harvest some time between the second and last weeks of July 2017 in your area of the UK. This variety is a second early and they store better than most similar potatoes, a couple of months in the correct conditions.
