My chinese chestnut sapling is still dormant- and it is mid July!?

In April I planted a dormant 2 feet chinese chestnut and it is still dormant. I can still see the green tips from the buds and when I scratch the bark, it is green. When I planted it I fertilized it and water it occasionally. In the Spring we had lots of rain too. So, I am not sure why it is still dormant.
