Considerations
Primary buds start to die near -30°F. Shrugs off hard continental winters.
Needs roughly 2550 growing degree-days to ripen, a mid-season variety (Winkler I-II). A mid-length season carries it most years.
Foliar-disease pressure is moderate for this variety, a regular spray program in a humid climate. Regular cover sprays through the wet months.
Susceptible to Pierce's disease. Only a threat in the warm, humid South and parts of California; cold-winter regions cure it naturally.
High vigor. Wants leaner ground and active canopy management, or fruit hides in shade.
Low heat tolerance. Bakes and loses acid on hot sites; favors cooler ground.
High water demand. Wants steady moisture; struggles on droughty soils.
Prefers soil pH between 6.0 and 7.0. Outside the band, lime or sulfur brings it in range.
Phylloxera-tolerant: own-rooted vines are fine.
These are intrinsic to the grape. On a real property, Folia scores each against your site; here they're shown on their own.
