Well here it is in early December and not surprisingly, most of the outside crops in the main garden, ‘bit the dust’ as they say—died. A few are still alive. It is warmer now—here are the results of those cold snaps we had.
The Toscana (aka Lacinato or dinosaur) kale got severely damaged. It is cold sensitive and although it’s not completely dead, it is unharvestable. Here it is with the leaves burned from the cold.
The Russian Red and Curly Leaf kale are still going and have some damage as well but the new growth is doing well. I haven’t watered them at all-nature has with a little snow and a nice rain the other day- almost an inch. I do have them covered with 2 layers of winter weight row cover.
The gourds are still drying in the field. Some are starting to get lighter in weight so I will put those in the garden shed to finish drying. The rest will stay outside until they dry more.
The green house is button up fairly tight now with just a little venting at the top panels. I’ve put the bubble wrap on all the windows (bubbles faced to the window) for extra insulation. I’ve also put the 4 barrels with water in them on the north wall for them to absorb heat in the daytime (I took them out during the summer), releasing the heat at night (the theory is that the sun which is lower and further to the south will hit them on the north wall and warm up in the daytime). I’m not sure I have enough barrels to do much good but even one degree will be helpful once it gets cold again.
I’ve planted 2 winter lettuce varieties in the green house as transplants back in early November. The cold hard varieties are a green variety-Winter Wunder and a red variety-Marshall Red Romaine. They both have made it so far through those cold snaps although they have slowed down in growth because of the shorter daylight hours. They will stop growing until sometime in January when the daylight hours start to get longer. Winter Wunder is my favorite lettuce but only grows well during the cold months. When it starts to get even a little warm, it will bolt. The lettuces have 2 layers of row cover over them at night and have some protection from the unheated greenhouse (at least from the winds). I’ve also noticed that the lettuces don’t need a lot of water now (about once every 2 weeks). It will be interesting to see if they make it Dec-February. Don’t they look wonderful in the winter!
There has been about a 4-7°F difference between the greenhouse temperature and the outside temperature at 7 am in the morning when I check everything. When I add the row cover at night I get about 4-6 degrees more protection. I’m not sure what to expect this winter since this is my first December-January in the greenhouse. Last year when we finished up the greenhouse I start planting on February 17th so now I will see if these established greens can survive Dec-Jan.
