It‘s aluminum and just there to protect the bark. I’ll leave it at Boon’s for now. The smell is great, but one can always be always sure that the roots are doing to be a mess.Is the thin-gauge copper wire at the base to hold the bark in place?
Very nice material and should only improve behind your measured hand......
Will this remain at Boon's for the time being? I might assume your there?
I do love that smell of a nursery-type mix prior to that first proper re-pot!!
