Yes, you can. Here are the basic steps: 1. Put your crocus corms in pots in October. 2. Find a cool environment in the approximate range of 38 degrees Fahrenheit to 45 degrees Fahrenheit to put the potted corms for 8-10 weeks. 3. During the time when you are chilling the crocus corms, water them as needed. 4. Move them into a more temperate environment. As you do, expose them to some sunlight. 5. Increase the amount of sunlight as time goes on. Continue providing around the same amount of water you did while chilling the corms. Within four weeks, you should have flowering. Alas, the downside of forcing crocus corms is that you have to treat them as annuals. The corms will not produce new flowers next year.
