- Why Is My Red Dragon Japanese Maple Mostly Green? | Home Guides | SF Gate
Many types of red-leafed Japanese maples are grafted at a young age onto a rootstock from a green-leafed variety.
Sprouts that arise from below the graft point are usually the color of the rootstock parent species.
Left unpruned, green shoots can eventually outnumber the red branches, so these sprouts should be pruned away when they appear.
