Maincrop potatoes are those varieties you buy with a view to storing and using over winter. You can usually start lifting them around 4 weeks later than the first earlies (2 weeks later than second earlies), at which time they will pass as new potatoes. Their real strength, however, lies in letting them grow to maturity and lift them for storage to see you through the winter period.
Although some of them are firmer in the flesh than others – the general rule is that maincrop potatoes tend to be more floury in the flesh – due to them containing more starch. This makes them excellent for producing chips, roast potatoes and mash, while you need to be careful not to overcook when boiling them.
Maincrop potatoes should be lifted towards the end of the growing season, and stored appropriately in a dark, frost free area.
