A fellow farmer friend and I were comparing notes on how we plant potatoes recently. Since lots of people grow , I decided to share our methods here. Boring post incoming.
The first thing we do is cut the potatoes in half or thereabouts, ensuring at least two eyes are present on each piece. We do not cut our fingerlings. The pieces then harden off overnight in our basement. We do not chit our potatoes. (New verb alert!)
Next, we trench into a w**d free bed, trenching about as deep as we can with several passes of our zipper tool. We place potatoes or potato pieces about 10-12” apart in row, firmly pressing the potatoes into the trench.
Then it’s time to make that “tillage” event worth it. In that trench we sprinkle a little bit of elemental sulfur to stave off common scab which does not like the slight acidity provided by the sulfur. We are working with about a 7.3 pH in our , so some localized acidifier can help us keep our potato crop healthy. Moisture is also medicine as it relate to scab, so don’t let that soil go bone dry!
Next into the trench is a drench of our vermicompost tea. We make beautiful worm compost in our worm bin, put a few cupfuls of the finished castings into a brew bag, and then brew that with rainwater, humid and fulvic acids, seaw**d extract, unsulphured blackstrap molasses, and fish hydrolysate. We let that brew for 24 hours with a bubbler going to oxygenate the water. And then we apply to our potato trench.
After the plants are 4-6” tall we will hill with finished compost. And then when they grow another 4-6” we hill again. We aim for a wide, flat top of a hill instead of a sharp, upside down V. This helps capture more water, and it gives more space for the potatoes to grow.
This has helped us grow beautiful potatoes over the years.
