Pokemon dream world breeding?

I just got my first DW poke and its a female exeggcute, ive been breeding it over and over in the hopes i can get a male exeggcute with harvest. Ive bred this thing 10000000 times and it keeps giving me babies with the chloraphil ability and nothing else. i was told that only the females can pass down DW abilities to the child and im breeding it with a ditto (japanese/shiny ;P) is there anything i can do to increase my chances of a DWA exeggcute?
