After gathering up a trunkful of free fertilizer we brought it home and hosed it off thoroughly because apparently the salt residue is not welcomed by the plants. I decided rather than have it just freeze outside for the rest of the winter, to make a temporary compost pile in an unused corner of the greenhouse. I layered the seaweed with cleanings from the chicken house floor, the contents of the kitchen compost bucket, and handfuls of soil for the benefits of all the busy little microbes. 
I have a feeling this might get smelly but time will tell, its just an experiment and something to satisfy that winter gardening call.I'm reading Eliot Coleman's Four Season Harvest, a wealth of information on cold weather crops in a variety of unheated structures. He has great advice on freeze proof crops like corn salad, spinach, etc, and a lot of greens I've never heard of but am ready to try. E.C. has his farm in Maine, zone 5, which is only half a zone warmer than southern New Brunswick so his ideas should work here, I think. He makes plastic tunnels inside his greenhouses to give the winter crops a double layer of protection. They are made of polyethelene sheets stretched over half moon shaped hoops made of 3/4 inch pvc. The plants grow more slowly in winter, my august planted mesclun has never bolted to seed or become tough and bitter like the summer crops will do.
My initial idea was to try and have fresh greens til Christmas but heck, why stop now? Today I planted some sugar snap peas, some spinach and radishes, just to see if they will germinate in January.
