For the first time I’ve actually seen some decent, non-vague, instructions on how to earth-up your potatoes, to get the highest possible yield. These are from a response to a letter in the latest Gardener’s World magazine:

  • Cover your newly-planted potatoes with about 8cm of compost
  • Then, when shoots are about 15 cm long add another 8cm of compost
  • Repeat as desired.

This means you should get more potatoes growing from the earthed-up stems, and a higher yield.
