Black Tulip Magnolia being eaten.

[DeborahJane]

Would anyone know what is happening to my magnolia and what to do about it. I've googled it and snails have been suggested. I certain haven't seen any but I think I'll go scatter some snail bait this evening.
I aslo really want to move it so it gets more sun and less wet feet which is apparently desirable but google tells me magnolias hate having their root system disturbed. Has anyone had any experience with moving a black tulip magnolia? I'd really appreciate some informed guidance.

I actually found a web and tiny insects so i sprayed with pyrethrum.
I really want to move this magnolia. Have read up and apparently should dig around carefully now, Spring, but not move til Autumn. Does anybone have any experience with moving magnolis. It's taller than me but that's not difficult.
