Most years we are not zone 7a, yet 7a does happen occasionally here, this year was 8b, very rare for here, 7b and 8a is most common here. 4 out of our 5 in ground pomegranate bushes have only been in the ground one winter, one of our 8b winters, so I am not sure yet how well they will do here most years.
Our “Salavatski” looks like it’s going to fruit this year for the first time, it’s in it’s 9th season in the ground. It was damaged by a weed wacker, then because of some 'Shothole borer" beetles the bush was messed up for 2 years, yet it came back strong eventually. 2 of them look like they will fruit their 2nd season in the ground, this year.
