The growths of terumah are terumah. And the growths of those growths are chullin.  But tevel, maaser rishon, after-growths of the she-mittah year, terumah from outside the Land [of Israel], meduma, and bikkurim — their growths are chullin.  The growths of hekdesh and maaser sheni are chullin, and he redeems them at the time of their seed.

[If there were] a hundred rows of terumah and one of chullin, they are all permitted in [the case of] something whose seed decomposes; but in [the case of] something whose seed does not decompose, even [if there were] one hundred of chullin and one of terumah, they are all forbidden.

With tevel, its growths are permitted in something whose seed decomposes; but with something whose seed does not de-compose, [even] the growths of growths are forbidden. Which is a thing whose seed does not decompose? For example, luf, garlic and onions. R' Yehudah says: Garlic is like barley.

One who weeds with a gentile among the pungent bulbs, even though his produce is tevel, one may eat from it casually. Sets of terumah that became tamei, if one plants them, they become cleared of [their] capacity to convey tumah, but they are forbid-den for eating until he trims the food. R' Yehudah says: Until he trims and repeats.
