I was thinking about how to keep track of the trees I now have, and any new additions in the future, including trees from air-layer, cuttings, etc.  Is there a prescribed method of indexing nursery stock and keeping track of who's strain they are, and how old each tree is?  What are the data points of a tree that should be tracked?

I hope I'm not asking too many questions, but I really want to do this right.  Thanks.

Udaman, the way I track mine is to give each tree or group of cuttings from the same source a number. If I receive others of the same variety from a different source, they get a different number. These number are put on the baggies or pots along with their names. Tree tags also bear the number and the name. I then keep a file of all my trees by number and name. I use Excel to make a sheet for each tree where I keep track of name, the source, the date, notes about, and a picture or two of the fruit and leaf. I also have that info in a note book just in case. I hope this helps.

I have each tree numbered with a brass tag. I keep all the info about name, source, etc. in a MS Word "table" on my computer. I also have a map that shows where all the in-ground trees are, and which is which.

Thanks for the input.  I'm organizing a numbering system that will relate each cutting to a family and keep that family separate from another within the same variety.  Your comments will help me simplify the process.

all i do is put a tag on each tree... what it is and who i got it from.  otherwise, there's really not much else you can know.  you buy/trade figs, and you are taking the person who is selling/trading with you's word for it, and unless there are substantial differences, like a supposedly gold fig tree giving you purple figs, you'd really have no way to ever know any differently.
