Considerations
Primary buds start to die near -8°F. Cold-tender; wants a mild winter or protected site.
Needs roughly 3050 growing degree-days to ripen, a mid-season variety (Winkler III). Wants a long, warm season; marginal in cool regions.
Foliar-disease pressure is heavy for this variety, a intensive spray program in a humid climate. A full, well-timed fungicide schedule is the management it asks for.
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.
High heat tolerance. Holds up to a hot, sunny season.
Moderate water demand. Average moisture needs for a wine grape.
Prefers soil pH between 6.0 and 7.0. Outside the band, lime or sulfur brings it in range.
Phylloxera-susceptible: plant grafted onto resistant rootstock.
These are intrinsic to the grape. On a real property, Folia scores each against your site; here they're shown on their own.
