Tulips bloom in early spring usually before the trees get leaves. This way, the tulips have sunlight when the flowers need it.
Quite possibly they are planted too deep or need to be divided.

Blue tulips are actually quite rare. Back in the day tulips were the rage. Almost everyone grew tulips and tulips made such a high price that murders were commited because of jealousy and greed for the best tulips. Tulips were often used with their bright colors to signify certain events. Now, tulips aren't that high priced. But the only tulip that you can get a high price for is the blue tulip.
