One who plants terumah flax -- [if he discovers it] before it has grown a third [of its full size], he must overturn the soil, but if it has grown a third [or more], he lets it remain, the words of Rabbi Meir. Rabbi Yehuda says, if [he had planted it] unwittingly, before it has grown [a third], he overturns the soil, but if it has grown a third [or more], he lets it remain, but if [he had planted it] intentionally, whether less than a third or a third, he overturns the soil.
