I planted a 30 foot by 3 foot raised bed of carrots. I am harvesting the carrots and have to get them out of the ground before the ground freezes. I plant the seeds around June 1st. We are getting below freezing temperatures at night for a week so he clock is ticking!
I use 4 mil plastic cover over the bed at night to keep the frost out and retain heat in the soil. I didn't water the carrots a lot this summer. The bed acts like a refrigerator until I am ready to pick them. The bed is 12 inches deep. I use 2 layers of 2X6 inch planks to form the bed. I also cover the bed with deer fencing to keep squirrels, possum, and raccoons out of the bed.

Mixing the batch. One packet makes enough for 4 jars.
