It’s pretty straightforward: no citrus scions or budwood (this includes curry leaf) plus no plants still under patent. And of course nothing that is sick or bug infested.
A shout-out to Martin Kou, Chair of Foothill for spreading the word and to the Orange County chapter for locating the list of current patents. Note that the spreadsheet shows some varieties highlighted in green which are now okay to exchange.
If you can’t open an Excel file, please let us know and we can send you a .pdf which is unfortunately much more difficult to read.
