You have to reach a score of 20,000 in only 15 moves! Just about every blossom is a bud & very few bigger blossoms are provided so it is very hard to get a blast or even bloom a bud for that matter. I have been stuck on this level for almost 2 weeks & I'm honestly getting to the point of frustration where I might just uninstall the game b/c there is no reason I should be stuck on this low of a level for 2 weeks!
