Time to garden?

I have been tending to my plants in the greenhouse since late November. This attempt has been very simple in plan and function. I have seeded the plants and have not supplied any artificial light or heat for them. I have been watering them as they require. There has been absolutely no fertilizer given to them. I wanted to test the idea that I would be able to grow through winter with my hobby greenhouse. So far, the results are mixed as seen below.


These are the two surviving Spinach plants as the other two did not make it.

These are two surviving Butternut lettuce plants.

And these are the two plantings of carrots. Both are doing quite fine even though the ones to the right appear not to be. Not sure the issue but if the carrots themselves are fine, then I am okay regardless.
I did a subsequent planting of Spinach, Chard and Butternut lettuce on January 1st. All seem to be healthy at this point as seen below.

The front row has all Spinach. I planted America in the left two pots and Bloomsdale Longstanding in the right two pots. In the back row, left to right, I planted Red Salad bowl, Black Seeded Simpson, Mesclun and Great Lakes Iceberg. 

In the left set of pots, I planted a complete set of Buttercrunch lettuce. In the right set of 3, I planted Giant Caesar, Little Caesar and another Buttercrunch lettuce.
The germination and growth rates of the January 1 planters were much slower than the earlier sets I planted. I believe that it was due to the fact that we had seasonably cooler weather with some nighttime lows in the mid 20's with a few in the upper teens during January. I know, shocking right? There was a winter blast that had the chill factor into the single digits and briefly below zero. Just the fact that the seeds germinated was a surprise to me. And antidotally, the plants that failed from the earlier planting did so during this time too. I will have to give some thought as to the whole growing idea in the greenhouse. I have a whole year to work that out so, for now, I will maintain the plants and see what happens.
Meanwhile, we had some beautiful warm weather this past Monday and Tuesday with highs in the low 60's. That gave me the opportunity to pull the remainder of the cement bricks from my garden. I also disassembled the winter structure I had. I can now see the form of my garden taking shape. The soil is way too wet to work at this point. We have had consistent rains so it is quite soggy right now. And given the conventional wisdom is to leave wet soil alone, I will bide my time. Below is a broad view of my garden and the wall of cement bricks I moved Monday. What I am going to do with all the bricks, I have no idea at this time.


My gardening juices are flowing as I work in and about the garden. I can't help but find something I can do. As I was sitting down watching TV Monday night, it suddenly came to me to see if the two pot lights I found in my garage would work in my greenhouse. So, at around 7 or so, I trudged out to my shed, plugged in an extension cord and wielded it into the greenhouse. I plugged the two lights in and took the following picture. I thought it was pretty impressive. 



My immediate plans are to begin thinking on what early spring crops I am going to actually grow. As most gardeners realize, when the space is limited, you have to be judicious about what you are actually going to grow. So, after having reorganized my 226 packets of seeds, I have some decisions to make.
Well, that's all the gardening I have to write about today. Hopefully your weather is turning warmer. Happy Gardening everyone!
