Left over herbs from last fall have sweetened dramatically with the cold weather. Have you ever had sweet cilantro? I hadn't until yesterday. It still tastes like cilantro, but is not sharp. The dill is fresh tasting, like freshly cut grass or clean laundry.
Remember the low tunnels from last year? I won't be looking at germination again this year, but I've set one up to jump start germination and growth of greens. Despite the low temperatures, the greenhouses are warm - as long as the sun is out.
