Do you grow tomatoes in the summer? Do you feed the birds in the winter? Perfect!
Now's the time to start saving birdseed bags to protect your small tomato plants when you set them out. You slit open the top and bottom of the bag, slide it over the tomato cage until the weather warms up a little, and you get a jump on the growing season. After you're finished with the bags, you can store them for next year or find another use for them or recycle them. Just make sure they're clean before you put them in recycling. I've heard terrible rumours about recycling depots throwing away tonnes of recyclables because they were dirty.
