Attempting to nudge the cold from the garden soil

I am making an attempt to try and make the Good Friday planting date.  I stretched some greenhouse plastic over the beds to try and warm things up a little faster.  We have finally broke through the clouds this afternoon with some sunshine which will help melt a little of the snow out there.
Organic Gardening recently had an article about solarization which is different than what I am try to accomplish.  Solarization would use the same technique, but would be implemented during hot weather so the soil would essential cook.  This would help kill weed seeds and "bad" fungus problems to "clean" the soil up for planting beds. I may be successful in germinating some of the weeds in the beds doing this now, but desperate times call for desperate measures.
I will keep you posted on the progress in my attempt to warm up my garden beds early.
