I planted a bunch of Ilama seedlings this year here in northern California (zone 9b). They grew well in the summer but since it got cold they have been dropping leaves, much in the way a Cherimoya would do in spring. I thought they were cold damaged but then I noticed the fuzzy new leaves starting to bulge out (see picture below), again just like Cherimoyas. It seems that they have the same rhythm as Cherimoyas, just 3 months earlier. Given that we're still at least 6 weeks from the end of frost season, this seems less than ideal.
Has anyone else in a similar climate experienced this behavior in their Ilamas?
