On the left is a row of hakurei turnips covered with agricultural fabric. In the center are two rows that I planted with winter rye that didn't come up as thick as I would like. On the right is a covered row of radishes. Both covered crops are still alive, depsite several nights in the lower teens. This section of the farm is a tiny hidden nook between the pond and some shrubs. Its location, in addition to the row cover, insulates plants from the cold.
