Can anyone please help? I recently purchased three acer plants (garnet, ever red & emerald lace) but the emerald lace has started to develop splits in the bark. It's even on the new wood (see pictures). It came from a local reputable garden centre, whereas the other two (which seem ok) are very small and were mail order.
My biggest concern is whether it’s a disease that could transfer to the two young plants.
If anyone can shed some light on this, I’d be really grateful
