Oshu Shidare Greening
I have an a. palmatum 'oshu shidare' in the ground in my front yard. It was planted early this winter while dormant. It's in partial sun. several hours of direct sun in the AM, some filtered sunlight mid afternoon, then shade in the late afternoon.
The leaves came in a nice red color but slowly have been greening out. And now are almost all light green.
I dont think it can be lack of sun. When I planted it I was concerned that might be too much for my hot humid climate. And I have bloodgood and fireglow in containers getting less sun and both are very red.
The big difference might be that my other maples are in containers. Im thinking a nutrional deficiency. But, while soil tends to be alkaline here, I'm skeptical thats the problem becuase this site was prepared with lots of organic matter including peat. The tree got a little fertilzer in early spring (tree tone by espoma, probably less than 1/2 reccomendation on label) Any ideas or suggestions? Thanks.
