I purchased 2 Blue Ischia from Hirts, one this year and 1 last year. The oldest is growing like crazy, straight up, one trunk. 30 inches, which will be pinched back or air layered to promote new branching. The new BI has a lot of shoots(8) coming from the roots and was like this when purchased. It is growing nice and I have not decided how I want it to form, bush or tree. TC plants grow vigorously, at least for me, I just hope they fruit as vigorously and tastes great.
