Trees on the Fereley rootstock are characterized by semi-vigorous growth, reaching 60–70% of the vigor of standard vigorous rootstocks. The rootstock ensures high and stable yields, as well as early onset of fruiting.
The plant possesses good tolerance to drought and temporary soil waterlogging. Low susceptibility to the sharka virus is noted, although sensitivity to bacterial infections at frost crack sites is possible. A distinctive feature is the extremely low formation of root suckers.
