Vine characteristics
Vigor and soil context
Plantgrape describes Barbera as vigorous, capable of high yields if vigor is not managed, adapted to dry, not very fertile clay-limestone soils, and in certain circumstances sensitive to potassium deficiency. These are attributed observations, not a fertilizer or water prescription.
Regional research context
Plantgrape notes high sensitivity to grey and sour rot, frequent grapevine leafroll-associated virus and, in California, Pierce's disease. These reference notes are not disease-management advice.
