A range of vine and vineyard management tools is often used to compensate for excessive growth. Vine and canopy management options include:
- Shoot hedging
- Lateral shoot removal
- Leaf removal
- Modified training systems
- Use of size-limiting rootstocks
- Root pruning
- Aggressive use of cover crops
- Regulated deficit irrigation
The experiment consisted of root restricted versus non-root restricted vines on three different rootstocks, Riparia Gloire (Riparia) (Vitis riparia), 420A (V. berlandieri x V. riparia), and 101-14 (V. riparia x V. rupestris) undergoing either under trellis cover crops (UTCC) or herbicide treatments. The following graphical summary shows that regardless of root restriction or rootstock, the under trellis cover crops (UTCC) was much better at controlling canopy density when compared with herbicide treatment. We will definitely be putting in a cover crop after we plant our vineyard to control canopy density and vine vigor which is one of the problems associated with eastern viticulture.
