Have often been sent phals my way for varying reasons, and yes some with severe root rot i.e no roots and same as Bruce without leaves.. Sphag and bag or similar humid environment- Coke bottle, terraium. Dont let the plant have direct water source contact. Spray twice daily underside of leaves aswell. Leaves have stomata cells whcih can absorb some moisture to help it on its brink of death. Not a great deal obviously but give it a go. To undergo this procedure you need the passion and patience of an devoted orchid grower. I have at times just positioned a chid, at deaths door, near a moss source i.e amongst a group of mounts where sraying/ misting is frequent and good results but our set ups are diff. Orchids are suprizingly tough at times and continue to prove us wrong. Its us thats the problem sometimes.
