I bet you think saffron is difficult to grow because it's so expensive. Right? Stop letting commerce tell you what to think and grow your own saffron, already! It's a desert plant, so it detests overwatering and wants LOTS of full sun. Plant the bulbs in fertile (but not overly fertile) soil. Containers are fine as long as the dirt is good. Water once or twice but that's it. In the fall, harvest flowers when they're open and fragrant underneath afternoon sun. Pinch off blossoms; do not pull up the corm! Pluck out the 3 red stigmas, let them dry, then heat them to about 100-120 degrees (I do it in my oven) and store them at least a month before you use them. If you don't age them, you won't get good flavor. Now, take care of the corms all winter and through the summer, watering only when necessary. Around July, dig them carefully and you'll probably be delighted to see that each corm has divided to two or four! Carefully separate those, replant with appropriate spacing, and repeat.
