I, too, bought a house last year with lots of greenery on some tulips
but no blooms. This spring - late February or so - as the tulips were
pushing through the soil, I put out some gentle fertilizer in their bed
(10-10-10). They ended up blooming beautifully.

Don't know if the fertilizer helped, or if they were just off last
year. I plan to try the fertilizer again next year.

Good luck!
