If they are in your garden, they might be planted too deeply, particularly if you have heavy soil. If they are in a shady spot, that might be a problem as well.

Do they go dormant at all? They need a few weeks of dormancy to form a scape. I'm thinking you grow them as evergreen plants and never give them a break, or too short of a break. Hold off on water gradually until the leaves yellow and come off. It'll then need at least a month to form a scape, which is when you start watering again. Also, if you're using fertilizer it may have too much nitrogen, which promotes leaf growth, not flowers. Get something with potassium. Hope this helps

Hairco, it's not clear from your post whether you have bulbs that are planted in pots or if they're planted in the ground. There is also no information about the level of light or how long you've had the bulbs. More information would be helpful, then people could provide better advice regarding what may need to be remedied. If you could post photos, that would be even better! You may have bulbs that are virused or have red blotch, which even in an ideal environment would fail to thrive because the bulbs themselves are the problem.
