What I do when shipping in cold or warm waether is I send everything in boxes that I insulate. I buy 1/2 foam housing insulation and cut it to size to fit he box. I purchase a 4'x8' sheet for around $9 then cut it as needed. It is a great way and chep way to help plants arrive in the best condition possible. Being from Nebraska I know how cold can affect the shipments. But like others have said, the biggest problem with plants is when they sit in a mailbox or on a porch for a long period of time. Whether hot or cold, that is the biggest problem shipping plants. I always ask a seller to PM me when they send the item so I can make sure someone will bring in the package as soon as it arrives. I have never had a shipping/receiving problem on this site. People take great care to make sure you get the best quality plants you paid for. Hope this helps.
