Did I plant my tulip bulbs too deep?

My husband bought me a pot of pink tulips for Valentine's Day and I planted the bulbs in late March because the weather was so nice. For some reason I guessed on how deep to plant them planted them 6-8 inches in the ground, instead to 2 inches. The temperture has dropped to frost twice since then but now everthing getting pretty warm and all my other plants are coming up. Did I plant them too deep? Did the cold hurt them? Or did I just plant them too late and maybe they'll come up next year? Or should I dig them up and plant them at the correct depth?

Did I plant my tulip bulbs too deep?
Tulip bulbs should be planted about 8 inches deep. They won't come up this year. If they were blooming in a pot when you got them, they were forced bulbs, and may not come back next year. Especially if the leaves died right away. The leaves stay on for quite awhile after the flower dies, to store food for the winter.
Reply:what you should do is dig around one of them...see if its sprouting...if it is you should be able to tell if you planted them too deep..i had bulbs i planted one year and they were too deep because most of what their stems were under ground..if your bulbs havent sprouted..i would say plant them to the correct depth...and either way if its too late for them to bloom now they will come up next year...
Reply:They only flower once a season so next Spring you will see them, just fertilize and leave in the ground.
Reply:They won't bloom again this year. Wait - they'll probably come up next year.
Reply:as far as i know you suppose to see the tip while planting them, you may want to dig them out and replanting.
