Grapevine (Vitis vinifera)
In Cadogno, agriculture and the cultivation of vineyards prevailed since pre-Roman times, traces of which can still be found in the street directory and in the rare undeveloped land. Maple trees (rump), planted in rows, were used to support it. This technique allowed the use of the land for hay and crops along the rows (i foss). The Bondola grape variety was predominantly grown, but from 1897 onwards, in order to combat phylloxera, firstly the Americana took over and then the Merlot, a variety of noble origin, which was grafted onto the base of the Americana vines. In the Campidoglio park, Stefano Haldemann, a winemaker from Minusio, planted rare grape varieties, leaving a significant historical legacy still used for educational trails.
