We're trying a different way of growing potatoes. No digging for this batch.
Instead we set potato bits on the ground, then covered 'em with mulch. Mulch consists of old, rotted straw, which our goats and chickens have been, ah, adding to for a couple of years. Ceredwyn says our now-vanished animals continue to feed us, even months and years after their demise.
We'll see how it goes, compared to our other potato plots: some in barrels (potato experiment #1), many in deeply-dug dirt trenches.
