My Japanese Maple leaves are turning Green

Help!! The leaves on my Japanese Maple have turned green (about 90% of them) there is still a little red but not much. Is this a soil issue?

Hi,
It all depends what variety it is, as a lot of Japanese maples do change colour as the season progresses, I shouln't worry to much.

Hi cg.
Like koiboy said, I would not worry too much.
My "Acer Palmatum Disectum garnet" went from deep-red/purple into light-green with some red and brownish (dried) edges.
This happened in July ! The timing is different every year. This is rather early but I am glad the leafs are still on.
So don't worry, be happy,
Piet, Tsubo-en

All true Japanese maples are variants of Acer palmatum. You have purchased a great tree but may have managed it incorrectly - hopefully not beyond recovery. Japanese Maples come in several leaf colors and forms. The easiest trees to propagate are the green-leaved varieties. So nurseries grow green root stock and graft red-leaved stock off that root.

You have allowed the green stock tree (which will sucker from below the graft) to become the dominant foliage. Your photo shows a classic example of this.

Manage only the foliage above the graft line (if you have any left) and remove all green sprouts below. The tree's symmetry may be upset for a while. Japanese maple is a slow grower and you must give it time to develop its natural form. Heavy pruning is not necessary nor recommended.
