I'm in the process of trading a rooted cutting and came up with this packaging. The roots are not established enough for any bare-rooting, and it's not possible to wait for the cutting to become more established which would be ideal. I have been unable to find any directions for sending such rooted cuttings, so came up with this. If there is a better way, I'd love to know.

The basic box I'm intending to use is one of those $5 'anywhere, any weight' priority mail boxes which will not hold a standard plant band of 2.5 inches wide in which the cutting had been growing.

To make sure the cutting will be as safe as possible, I want to send its roots in a rigid container. For this, I've cut down a 2 quart milk container as shown in the pictures and transplanted the rooted cutting. I've also added drainage holes. It's currently in a humidity chamber while it further stabilizes this recent transplanting.

Construction-wise, I used scissors to cut the 'milk' carton, and pruning sheers to cut through the bottom very thick part. Make sure your final width will not exceed the depth of the shipping box - it's not cut exactly in half - that would be too big - about a half inch or inch band is removed. The shipping box is just under 1.75 inches deep, so the cut carton will need to be a touch narrower.

Put in the drainage/air holes at any time before you put in the plant to prevent crushing/disturbing of the roots. You can hold the two box halves together with a rubberband if that makes it easier. Then use packing tape to wrap the whole thing near the top to hold it all together, not covering the drain holes (or recutting those you do). I also clipped off a corner to make sure drainage could be complete. Then carefully tranplant your plant disturbing the roots as little as possible - though some disturbance will happen when moving into a smaller container. The one in the photo was transplanted several days ago and seems fine.

When time to ship, pack up/stabilize the young plant in the same way you'd send a more mature plant. It's not time for that yet, so there are no photos.

The most important two things are 1) making sure that cutting and soil mix do not come out of the pot (milk carton or whatever) and 2) that the weighty part, the pot and soil, does NOT move around inside the box during shipping.

Earlier in the year I had ordered some small figs from EL and marveled at how well they had been packed. I will do something similar - hold the soil in place with tape and perhaps some padding. And use stakes/sticks to keep the 'pot' in place. But I will tape the stakes to the outside of the 'pot' ('floor to ceiling'), and probably also tape the 'pot' into the box. The recipient will have to cut it out of the mailing box -- but it won't move. :)

When it's time to send, I hope to add some pictures of how I secured it in the box.

I have received some exceptionally well-packed plants from Bass and Jon.  I defer to what they recommend.

So would I, but I couldn't find any directions for packaging anywhere. Do you have a link?

I don't.  I'm hoping they'll provide details, and I'm kicking myself for not taking pictures ;)

Sounds like you've done as well as can be done with the sticks and tape.  That's how I send things.
