Maincrop Potatoes to Grow

Maincrop potatoes to grow

We pick some of the best maincrop potatoes to grow for baking, mashing and roasting.

Maincrop potatoes are generally the largest you can grow, needing 15-20 weeks to reach full size. By the end, you’ll be rewarded with large potatoes that store well and are ideal for mashing, roasting and baking.

One benefit of growing your own potatoes is that you can choose varieties that aren’t available in the shops, with a wide range of textures and flavours.

If space is limited you could plant maincrops in large pots or bags, although the tubers will have more room to develop in the ground. To get a good harvest, grow potatoes in a sunny, sheltered spot, ideally in slightly acidic soil. Improve the soil before planting with some well-rotted manure, and feed while in growth.

Harvesting maincrop potatoes

Wait for the foliage of your maincrop potatoes to turn yellow and die down before you harvest them. Choose a dry day to fork them up, then cut off the foliage and discard any damaged or diseased tubers.
