Plant maincrop potatoes from March. Prior to planting, 'chit' the seed potatoes by setting them out in a cool, bright position (10C/ 50F) to allow them to sprout.

When growing maincrop potatoes in the ground avoid planting in soil where potatoes have grown for two years in succession to reduce the risk of disease. Prepare the planting area in a sheltered position in full sun on moist well drained soil. Dig in plenty of well rotted manure. Plant potatoes in rows at a spacing of 45cm (18"). Rows should be set out 75cm (2', 6") apart. Place the seed potatoes into 10cm (4") deep trenches and backfill the soil to refill the trenches. When shoots reach 20cm (8"), mound up soil around the shoots leaving just a few cm showing. Repeat this process after a further 3 weeks.

Where space is limited, try growing potatoes in potato bags on the patio. Fill an 8 litre potato bag to just below the top of the bag with good quality compost mixed with some well rotted manure. Carefully plunge a single chitted potato tuber into the compost with the shoots pointing upwards at a depth of 12cm (5") from the soil surface. Place the bags in a sunny position and water regularly to keep the compost moist.

Weed between rows and keep potato plants well watered throughout the growing season. If the risk of frost threatens, draw some soil up around the stems to protect them, or move potato bags to a frost free position in a shed or greenhouse. Maincrop varieties can be harvested approximately 20 weeks from planting when the foliage begins to turn yellow and die back.

  1. best iv ever grown.

    By edmund parsons 18-09-2015

    this variety is very reliable grows strongly and has the best slug resistance of any potato iv grown. blight resistance is so good i dont need to remove foliage or spray. boiled texture is a bit powdery is only down side, but this texture leads to amazing mash.


    Thank you for taking the time to post your review. I am glad to hear that you have been happy with your order. I hope we can continue to be of service to you in the future.

  2. Would be perfect if not for the slugs.

    By Guy Lovejoy 16-09-2015

    The slug resistance advertised does not seem to have prevented a large amount of slug related damage to my tubers.


    Thank you for your review. I am sorry to learn of your disappointment with your purchase. Unfortunately, while this variety is slug resistant, it does not completely prevent any damage from slugs. There are many measures you can take to control damage, but it is very difficult to completely prevent it. If you would like to contact us at, one of our agents will be more than happy to offer some help and suggestions.
