That's pretty much it -- buy gems. You do get a gem when you reach leaf two (I think it is) with crop mastery, and sometimes there are promotionals whereby when you download and start a promotional game you will receive some free gems.
This particular topic has been well covered around the forum. Just dig around and you'll find threads and more on the subject.
