Theophrastus, Enquiry into Plants 3.1.6
A little bit of agricultural advice.
ἁπλῶς γὰρ τὸ μέγιστον (ὥσπερ πολλάκις εἴρηται) τὸ λαβεῖν οἰκείαν ἀέρα καὶ τόπον· ἐκ τούτων γὰρ ἡ εὐθένεια καὶ εὐκαρπία. ταῦτα δὲ ἐναντία φαίνεται τοῖς παρὰ φύσιν ἡμερουμένοις.
In a word, the thing of greatest importance (as has often been said) is that a plant should receive its proper air and location; from these things come abundance and fruitfulness. But they [i.e. air and location] seem to work in the opposite way for plants cultivated contrary to their nature.
