Cardinal grapes are typically harvested in late summer to early fall, depending on the climate. They are characterized by their thick skins, which contribute to a longer shelf life and resilience during handling. However, they are susceptible to certain diseases and require regular phytosanitary treatments, such as those based on copper and sulfur, to maintain healthy crops. In the Philippines, particularly in the Ilocos region, Cardinal grapes were introduced in the 1970s and have been cultivated for both local consumption and export.
