Solanum tuberosum 'Sarpo Mira'PBR
potato 'Sarpo Mira'
A high-yielding, red-skinned late maincrop variety that produces a good amount of weed-smothering foliage, but it is the potatoes natural resistance to blight that makes it stand out from the crowd. It is a good all rounder in the kitchen and has a floury texture that is great for baking, roasting and making chips. It also has good crop yields and stores well so the good harvest potential will mean you do not have to eat them all at once. Also shows good resistance to Potato blackleg, slugs and some potato viruses.

How to grow
Cultivation
Grow in an open, frost-free site with deep, fertile, moisture-retentive soil for high quality and heavy yields. Improve soil by adding organic matter, such as well-rotted manure, in the autumn. Draw earth up around the stems as they emerge, to exclude light and prevent the potatoes from becoming green. Water well in dry periods. Potatoes can also be grown in large containers or potato gro-bags. See potato cultivation for further advice.
Propagation
Propagate by chitting tubers or 'seed potatoes'. This is done by standing the tubers 'rose-end' up (the end with the most eyes) in egg boxes or trays in a cool, light place. After two to three weeks the shoots will begin to sprout. Plant out after frosts have passed, from about mid March to mid April.
