Thuja Plicata turned red
I planted 6 Thuja Plicata 30cm plants a year ago, one of them has turned red a few months ago, the rest are fine.
It's the same height as the other plants and looks healthy apart from the colour. It has also got a green child and abnormally thin base (see pictures).
What is going on, shall I leave it as it is or cut off the child
