Might have been a space saving idea. Walkways between each row of plants
uses up a lot of gardening space.

Wrong place to ask I know ...but...
Yesterday I noticed a field of potatoes with the crop just emerging.
However
unlike the traditional one row of potato plants per mound there were three
rows per wide mound.
Is this a new method ? What's the advantages?
Any advice welcome.
Thanks.
