I'm going on a distant memory

, but I once read an article on forcing bulbs. I'm actually trying it right now.
I planted several daffodil bulbs in a clay pot, and stuck that in a plastic bag. I left the bag loose, just to contain dirt if it should get tipped over, and put it in the fridge. This was in late Sept., and I just took it out. So it was in the cold for about 15 weeks. I watered it and set it in the window with the most light. I'll check the water daily, and with some luck I'll have flowers in early spring. (I have another pot in the fridge still, I'll pull it out in a couple weeks). This was just an experiment, since I couldn't get all the bulbs I'd bought in the ground in time last fall.
