Some boxes only have one variety, so just label one piece of tape and lay on top of moss.

A consideration when putting multiple varieties in the same box in layers: They all most likely will not root at the same time. If you go in to retrieve the rooted ones, it's easy to damage those which may need more time. Not saying you can't do it, just be careful. The same can be said  when rooting just one variety and you have a mixture of week tip cuttings and nice fat hardened cuttings, or for that matter cuttings from different trees. I just finished my first round of cuttings and potted out of some boxes (mixed varieties) 3 times over a period of two weeks. Running about 95% rooting. Appears that I am losing a few of the thinner tip cuttings (purchased ones) in the SIPs. Did another head count today and looks like I will still achieve around 90%.
