Potato types explained
Confused by the different potato types? We explain the differences between first early, second early, salad and maincrop potatoes in this short guide.
There are three main types of potato to grow, named according to when you plant and harvest them: first earlies, second earlies and maincrop.
First early or 'new' potatoes are so-called because they are the earliest to crop, in June and July.
Second earlies (also called 'new' potatoes) are hot on their heels, taking a few more weeks to mature. They are ready from July.
These two types are expensive in the shops and taste better when just been harvested, so many people grow these. They also take up less room and are less prone to potato blight, as they are generally harvested before the disease has taken hold.

Maincrop potatoes take the longest to mature and are harvested from late August to October. They are suitable for baking, roasting and mashing, and can be stored for a few months.
Growing potatoes is easy – plant one seed potato, and you dig up lots of potatoes a few months later. Find out all you need to know about growing potatoes in our potato Grow Guide.
