Ἡ δὲ γεωργία, δυοῖν ὄντων ἐξ ὧν αἱ τροφαὶ καὶ εὐσθένειαι τῆς τε γῆς (καὶ τοῦ ἀέρος, τὴν ἀπὸ τῆς γῆς) παρασκευάζει βοήθειαν· τὸν ἀέρα γὰρ οὐκ ἐπ' αὐτῇ ποιόν τινα ποιεῖν ἀλλὰ δεῖ πρὸς τὰς μεταβολὰς τὰς κατὰ τὰς ὥρας γινομένας αὐτὰ τὰ δένδρα καὶ τὴν χώραν διακεῖσθαί πως ἵνα τε ἀπολαύῃ τῆς πρὸς αὔξησιν τροφῆς καὶ μὴ πάσχῃ μηδὲν ὑπὸ τῶν ἐναντίων· δεῖ γὰρ καὶ πρὸς ταῦτα φυλακῆς, λέγω δ' οἷον τομάς τε καὶ διακαθάρσεις καὶ βλαστολογίας καὶ κοπρίσεις καὶ σκαπάνην καὶ ὅσα ἄλλα πραγματεύονται.
