Mishnah/Seder Zeraim/Tractate Orlah/Chapter 1/6
What happens when roots get mixed up?
נטיעה של עורלה ושל כלאי הכרם, שנתערבו בנטיעות--הרי זה לא ילקוט; ואם לקט--יעלו באחד ומאתיים, ובלבד שלא יתכוון וילקוט. רבי יוסי אומר, אף יתכוון וילקוט, ויעלו באחד ומאתיים.
If a shoot of orlah or a shoot of kilayim became mixed up [in the case of kilayim the example would be, where he placed a perforated planting pot under a vine, thus both the vine, and now this new plant, are drawing nourishment from the same ground; subsequently, he removed the pot and doesn't remember from where], he must not gather them [since plants while still attached to the ground have no neutralization]. However, if he did gather them, it becomes neutralized in [a mixture of] two hundred and one, provided that he did not gather them with this purpose in mind [since the Rabbis prohibit doing so intentionally]. Rabbi Yose says: Even if he gathered them deliberately [in order to neutralize them] it becomes neutralized in two hundred and one [because the Rabbis did not institute precautionary measures in uncommon cases such as these].
