Hi Paula,
The link below is part of the FAQ for the plant exchange forum. (There used to be a photo explanation somewhere but I can't find it.) I'm sure you didn't realize there was a FAQ there and that this question should been placed on the Plant Exchange Conversation board and not here. I hope that didn't sound mean because I didn't mean it that way. Everyone posts in the wrong spot when they first start : )
Anyway, I do do a few things differently than the FAQ. I often dig and pot all my extras and keep them in a pot ghetto. This way I know exactly what I have and it is easily retrievable. I think people get in trading trouble not realizing how time consuming all the digging is, running short on what they have etc. Plus anything that came up a bit short on roots will regrow in the pot quite quickly and travel much better than a shocked fresh dug plant.
Another thing I do differently is use tape to tape the baggie at the base of plants. I personally can get a better snug fit to keep the moisture around the plants.
I do roll them up in newspaper cone as the FAQ suggests. I think they survive much better. Then I use extra crumpled newspaper or crumpled bubble wrap(not wrapped around so plants can still breath) as padding. When I think I have it packed good, I close the box and give a good shake. If anything moves, I add more padding.
The FAQ also says to use Priority mail which is true. Regular boxes can take forever to arrive! Also, I always get a Delivery Confirmation #. Packages seem to arrive at their destination better that way, and no one can say it didn't arrive.
I hope this helps: )
