Your tree look good. When it sends out red buds, or red new leaves, or leaves with red hue, it means the tree is very healthy. Good luck.
The fruits are indeed very delicious and very unique. I’m glad that you like them. Which variety did you try?
I think it is about to push right now, it has been on pause for a very long time in the peat moss I used to root it. Unfortunately many roots broke off when I up-potted it into FoxFarm, but it's still looking ok overall. The peat moss was maybe not the best medium for rooting and I would go 50/50 with FoxFarm peat next time, the peat didn't have enough nutrition and I think it held it back, even from building roots. It was just luck this one survived.
I got the black pearl variety from Calmei. Very good, but VERY expensive. For me it was worth it because I've already spent $400 on yangmei trees so I absolutely needed to know if it was worth this $ and effort.
In my opinion it is worth my losses and I'm very happy to have a tree despite all the heartache. I would try again if we got another good deal for big trees again.
