Tulip bulbs are planted in the fall. They need a period of cold weather to break dormancy. I don't know your specific growing zone so all that I can offer is general advice. Gardeners who live in zone 7 and north, should plant their tulips one month before the ground freezes. In zone 8 and warmer (south), the winters aren't cold enough so gardeners chill their tulip bulbs in their refrigerators for 10 weeks before planting them in their gardens in December or January. I fear that you have planted your tulips much too early. They may germinate, but they may not bloom. I don't know if they will come back. Unlike daffodils which come back year after year and multiply, tulips are more fussy about their growing conditions and usually don't last more that a few years and don't multiply.
