I planted the seeds in late October in southern New Mexico, zone 8b. I thought it was too late to plant but this daikon did very well in my 12-inch deep raised bed throughout winter with frost cover. The bottom of my raised bed has weed barrier fabric and I was afraid if I could grow long daikons in my raised bed. All daikons have been straight and long as I hoped for. With some frost, the flesh becomes sweeter. I’ve intended to use it for cooking but it tastes too good to use it for later each time... My 5-year old eats it raw without condiments. The leaves are very yummy in soup and sautéed.
