My two Schlumbergera opuntioides arrived well wrapped and packaged, but sadly one of the plants lost most of its roots in transit, hopefully it will recover; the second (larger plant) seems in excellent condition. I just love these, I have a lot of them from Candy Cactii.
Only, package material can be improved. Cacti and other succulents are sensible for movement due to spave left in the parcel. Package deliverers do throw with parcels and put small parcels underneith bigger and heavier parcels in a transport container. Parcels will be crushed and plants within a parcel will be damaged.
