Reference for Kilayim 4:7
הַנּוֹטֵעַ שׁוּרָה אַחַת בְּתוֹךְ שֶׁלּוֹ, וְשׁוּרָה אַחַת בְּתוֹךְ שֶׁל חֲבֵרוֹ, וְדֶרֶךְ הַיָּחִיד וְדֶרֶךְ הָרַבִּים בָּאֶמְצַע, וְגָדֵר שֶׁהוּא נָמוּךְ מֵעֲשָׂרָה טְפָחִים, הֲרֵי אֵלּוּ מִצְטָרְפוֹת. גָּבוֹהַּ מֵעֲשָׂרָה טְפָחִים, אֵינָן מִצְטָרְפוֹת. רַבִּי יְהוּדָה אוֹמֵר, אִם עֵרְסָן מִלְמַעְלָה, הֲרֵי אֵלּוּ מִצְטָרְפוֹת:
If one plants one row [of vines] on his land and one row on his neighbor's [adjoining land], and [even if] a private path or a public path is in the middle [between he two row], or a fence that is lower than ten handbreadths high, they combine. [If the fence is] higher that ten handbreadths high they do not combine. Rabbi Yehudah says, If he intertwines them [the vines] above [the fence] they combine [even if the fence is higher that ten handbreadths].
