Why Choose Gravesac?
Gravesac is a well-balanced rootstock valued for its combination of vigour, production consistency, and adaptability.
It is often selected by growers seeking more vigour than 3309 C while maintaining balanced vine growth and reliable production.
Its excellent graft compatibility helps promote uniform vineyard establishment and long-term performance.
Adaptation to Canadian Conditions
Gravesac can be particularly well suited to Canadian vineyard sites where spring moisture may slow vine establishment and early-season growth.
Its moderate to high vigour can help support vine development in sites where lower-vigour rootstocks may limit growth.
In Canadian vineyards, Gravesac is often considered when growers want additional vigour compared with 3309 C while maintaining good vegetative balance.
Soil Pest Resistance
- Very high tolerance to root phylloxera
- Susceptible to Meloidogyne incognita and Meloidogyne arenaria nematodes
When Should You Consider Another Rootstock?
Another rootstock may be a better choice if your vineyard has:
- Very dry sites or soils exposed to prolonged drought conditions
- Low water-holding capacity
- Significant nematode pressure where greater resistance is required
Gravesac is generally best suited to sites where balanced vigour, consistent production, and adaptation to acidic or well-drained soils are desired.
