Year old corms are small that's why the ones you buy are expensive, the older they get the bigger they get. I wouldn't waste them personally, they're easy enough to grow on later this year and will eventually save you money. Once they get to about 2-3 inches in diameter you can literally cut them into sections, each with a bud and get new corms for free. The only new ones you ever really need to buy are new varieties with new colours or features.
