Wills, I have a strong suspicion that a fig that splits planted in ground will split in a covered SWC, but I may be wrong. The reason I say this is because my in ground Sal's Corleone tends to split whether it rains or not. We are currently going through a dry spell here in Tallahassee and this fig is still splitting. Other varieties may differ but unless you really, really want a particular fig, I would avoid those that tend to split.
