I know youre Very busy so Thanx for the update
!! That's some great growth for one summer! Didnt see PK-3 though. Is it still alive? Although, shouldn't matter much with 2 plants as big & healthy as PK-1 & PK-2 are. You've done an outstanding job
!!
You seemed concerned with growth stopping. A similar thing happens with Gingko Biloba trees. It's normal for them to put on a lot of new growth, one year, then no growth the next year - even under identical growing conditions. Nobody has found an explanation for that, either. Gingkos have been around since the Jurassic period. Strange how some plants act.
I'd say good luck But what you got was more from skill & experience. Super job, hope the weather & stuff works out great for you!!
