3,236. Produce That Must Be Tithed, Which Got Mixed With Produce That Need Not Be Tithed

Terumos 2:12

Let’s say that someone declares standing grain ownerless, he acquires it, and then he acts counter to the law by taking terumah from it. In such a case, it is terumah. However, if he declared sheaves ownerless, acquired them, and then acted counter to the law by taking terumah from them, they are not terumah. Similarly, if one takes terumah from produce that need not be tithed, it’s not terumah. Produce that people don’t normally plant in their gardens and fields, but which one can assume grew ownerless, is exempt from terumos and maaseros. Such produce includes very strong species of garlic and onions, Kilkilian beans, Egyptian lentils, et al.

Terumos 2:13

Let’s say that produce from which terumah must be taken got mixed with produce that is exempt from tithes; for example, olives gathered by the needy got mixed with the harvested olives, or undergrown grape clusters got mixed with the harvested grapes. If the owner has more of this species, he separates from that the appropriate measures of terumah for all the produce that is so obligated. If this is all of this produce that he has, then he takes terumah and terumas maaser for the whole mixture as if it were all obligated in terumah. He then separates first tithe and second tithe in the appropriate measures for the produce that is so obligated.
