Coldframe winter gardening can be done in fairly extreme climates. It’s February which ends the Persephone garden hibernation cycle. The sun is now strong enough that the spinach I planted in late September, will begin to grow again. I just need to turn on the lights. The windows that sit on top of the cold frames are called lights. I have to brush off the snow that’s blocking the February sun from reaching the spinach leaves.
Planted 9-23 ——– 1st harvest ? ———- final crop ?
