Today is nice, but tomorrow is supposed to be cold and snowy, so today I will head by the garden center at Home Depot and buy several bags of top soil and humate (at 40 lbs per bag, 10 bags at $1.25 each is a modest investment that helps keep the truck on the ground in the ice). I'll let it ride around back there till spring, when it will go into the garden. I have several places I've been slowly building up with imported soil, and since I don't know where it comes from, I make sure to mix in soil amendments (lava sand, greensand, decomposed granite, sometimes worm castings if I have them) and some of my back yard compost. This helps with the micro-nutrients in the soil and the compost helps establish the biological activity of the rest of the garden.
I'll buy more "Southwest Blend" bird seed at the same time. The little buggers can empty a feeder in a day. It introduces a lot of weed seed for next spring, but they are delightful to watch. Once again they're acclimated to me filling the feeder - they used to disappear for hours when I started filling them, but now I'm barely back to the kitchen window and the scouts are already knocking seeds out of the little trays.
