The Chef was impatient, the potato seed was becoming wizened, so he planted his potatoes in the plot.
The Chef worked on the soil to warm it up. In the morning, he dug a 4″ trench when the sun was shining & covered it with fleece. By 3pm the soil had warmed up to 7 degrees.
So, he planted the seed potatoes in the bottom of the trench and covered them with a thin layer of soil. Fleece was then placed over the top of the planted potatoes to keep the warmth in.
One row of Maris Bard potato seed was planted about 12″ apart. About 15 tubers were planted altogether.
