Considerations
Primary buds start to die near -5°F. Cold-tender; wants a mild winter or protected site.
Needs roughly 3500 growing degree-days to ripen, a late-season variety (Winkler IV-V). 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. Plan on a full, well-timed fungicide schedule.
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.
Drought Adapted water demand. Does well on dry, well-drained ground without irrigation.
Prefers soil pH between 5.5 and 7.5. 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.
