I'm not sure what's going on here. My Misi Luki and Blue Java have exploded with growth over the summer, but my Pisang Ceylon has barely budged. Other than the lack of growth it seems to be pretty healthy. It was also growing fine in the pot before I planted it in the ground.
Underside of the newest leaf:
Oh, and it's planted in a mix almost identical to my Misi Luki. I believe it was 2 parts composted potting mix and 1 part native garden soil (which is rich but really heavy clay).
The Misi Luki. It's not even funny how fat this thing has gotten:
The only other real difference is that I found partially decomposed woodchips in the first few inches of soil of the Pisang Ceylon. Could the bacteria that's breaking them down be robbing nutrients from the plant? Any help is appreciated.
