Techniques for Managing High-Vigor Vineyards
The bountiful natural terroir of Oregon has left many vineyards with excessive vegetative growth. High vigor can lead to a host of deleterious effects on grape and wine quality. Many grapegrowers annually employ intensive remedial canopy management techniques in response to high-vigor issues. The speakers in this session will address perennial vigor management strategies. From New Mexico State University, Dr. Gill Giese will share results from a long-term study of complete vineyard floor cover cropping and root pruning. From the University of Georgia, Dr. Cain Hickey will discuss results from research on the use of root restriction and rootstocks as a vigor management tool.
