That's about exactly how it is over here - radishes just sitting in suspended animation under the plastic. Romaine lettuces keep coming pretty well, and arugula has been good but I think it's finally freezing to death despite the cold frame. Kale looks pretty bad - I am waiting to see if it perks up in another month and starts growing again, or whether I've killed it with inadequate protection. Got some of the claytonia seeds but haven't planted them yet. Pretty much enjoying a limited harvest (but amazed to get anything at all in January cold), and I've figured out so far that I should have planted these crops about a month earlier in the Fall than I did. The Winter seems to be just a long refrigerated extended harvest period, but not a germination time or even much of a growing opportunity. Next Fall I will be more keen about my planting plan. I am learning a lot from the Eliot Coleman book. This is more "touchy" than warm weather growing, but fun nonetheless.

Hi,
I have about 6 inches of powder snow on my low grow tunnels thanks to this weekends snow storm in the North East. The snow sure changes the temperature profile in the tunnels.

My wireless sending thermometers are still sending temperature info to the receivers in my house - Walmart $15 units. (Every several weeks I have to bring the sending units in the house and give them a shot with a hair dryer). I have one unit for outside air temperature in the garden, one inside a tunnel for tunnel air temperature, and another in the tunnel with the sensor about 1" deep in the soil.

Prior to the snow, temperatures Farenhight were as follows on Jan 17th.
Day Max (Outside, Tunnel Air, Tunnel Soil) = 32,35,37
Night Min (Outside, Tunnel Air, Tunnel Soil) = 14,17,35
Sometimes the air in the tunnels was 0-3 degrees warmer than the outside air at night, sometimes 0-3 degrees colder.

After the snow, temperatures Farenhight were as follows 22 Jan:
Day Max (Outside, Tunnel Air, Tunnel Soil) = 17,25,33
Night Min (Outside, Tunnel Air, Tunnel Soil) = -3,14,32
The snow is clearly acting as a good insulator. Of course, no sunlight is getting through. I suspect everything inside is in suspended animation. The radishes and Mache / Corn Salad looked fairly healthy prior to the snow.

I think I will leave the snow on the tunnels unless they start collapsing. Its the least work approach, plus I don't think the little sunlight they would get would cause them to grow.

Anyone have any thoughts - Leave Snow on - versus Remove it? Thanks.

Wel I went out mid Jan. and picked the rest of my carrots. I burried them in leaves in the late fall. The day I picked was 0 degrees with six inches of snow fall! Not bad! I have one more butternut sqaush left and spinach over wintering in my cold frame and un protected ground.

Raisemybeds, Yes that cold! Burrrr. Been getting hit with some cold weather up here. Quite a few 0 and below days the last couple of weeks. This mouring was -8. We have overwinter kale up here many times before. I yanked all mine in the fall. Good luck with your harvest!
