Last year it happened by accident.
This year I did it on purpose.
I left some of our potato crop in the ground over the winter under heavy mulch.
Some of the potatoes turned to mush and some of them were of awesome quality.
Firm, hard white flesh….and delicious.
Compared to the potatoes still in the potato bin in the basement…well there was no comparison 😉
I’ve been playing around with the heavy mulch gardening model the past 3 years (Ruth Stout’s claim to fame).
Today I scraped off the mulch on both garden beds. The soil under the mulch is still frozen solid while the rest of the ground seems to be pretty much thawed. Mulch not only suppresses weeds it also acts as an insulator and would have kept the ground frozen a lot longer.
Over wintered potatoes in Iowa soil under heavy mulch.
Just curious if any of you have ever tried (or heard) of doing this before? (over wintering root crops until spring)
In the pioneer days, I know the settlers would bury apples, and other crops in earthen pits. The soil temperature below the frost line remains a constant 55 to 57 degrees which is warmer than a refrigerator but lower than a warm house.
This is a little different process because I know the potatoes in the garden froze, in spite of the mulch…they were not 3 feet down below the frost line.
