Hello, my significant other and I are new to this board, he's a Landscape Architect and I'm a Civil Engineer. We both enjoy landscaping and have done quite a bit this past summer at the house we bought in the
spring. We bought a japanese maple (prox. 15 gallon bucket) and planted it over Memorial Day weekend in about 90 degree weather. The
tree has done well, it was planted properly (with all the fertilizer and layers and mounding so no standing water, etc.) and was a beautiful red color until about a month ago - when it turned green. Our question is, does anyone know why it turned green (our best guess is that one of the parents of the cultivar caused it to revert back to green) and/or what, if anything, can be done to make it be red again? It's a Trompenburg variety. Any help/input would be greatly appreciated!
