How are you growing it? Indoor/outdoor? Has it sprouted or just planted? Make sure your humidity is between about 55-70%, which can be done easily with a humidity dome or a ziplock bag fitted over the top of the container.
FYI: Pics and a grow diary will help the community answer your questions better! More details the better.
I'm growing in doors at the moment as iv just potted, then iv got a zip up green house out side. I'm from UK so weather is OK atm.
I have used a soil that is meant to be good for them to.
