We have about 200 crocuses in our front lawn. Every year they come up early spring, usually poking their heads through the snow. This year, they came up, but only a few had flowers. The rest just came up as foliage. What could cause this?

Too much nitrogen or too little phosphorous can cause this. Use a balanced fertilizer on your lawn rather than the normal high nitrogen fertilizer recommend for lawns. This should help balance it back out.
