These are a variety of Yellow Carrots which are less sweet than the orange varieties
Note, the dark colored soils (humus present) - as these soils are insulated with a 4 - 6 inch layer of leaves with a clear plastic cover over the wintertime carrot bed. Worms and microbes are still very active in these non-frozen soils. This is a nifty way to regenerate soils, that is re-compost, used compost throughout the winter. Other nearby uncovered beds do not have the worm activity in them and are frozen solid. With a little ingenuity we can eat out of our gardens all winter long and also enjoy this natural soil building process. WORK LESS & GROW MORE!
