Reference for Orlah 1:3
אִילָן שֶׁנֶּעֱקַר וְהַסֶּלַע עִמּוֹ, שְׁטָפוֹ נָהָר וְהַסֶּלַע עִמּוֹ, אִם יָכוֹל לִחְיוֹת, פָּטוּר, וְאִם לָאו, חַיָּב. נֶעֱקַר הַסֶּלַע מִצִּדּוֹ, אוֹ שֶׁזִּעְזְעַתּוּ הַמַּחֲרֵשָׁה, אוֹ שֶׁזִּעְזְעוֹ וַעֲשָׂאוֹ כְעָפָר, אִם יָכוֹל לִחְיוֹת, פָּטוּר, וְאִם לָאו, חַיָּב:
A tree that was uprooted together with its rock-soil [the hard soil which is wrapped around the roots], [or] was swept away in a flood by a river together with its rock-soil, [and one added more soil and it started growing again], if it could have lived [just from the rock-soil] it is exempt; if not, it is subject. Rock-soil that became detached from one side, or that a plow shook it off, or that he shook it off until it [the rock soil] turned into loose soil, [and one added more soil and it started growing again], if it could have lived it is exempt; if not, it is subject.
