When it comes to starting a vineyard, picking the right grape variety gets a lot of attention—but what about the rootstock? Think of it as the foundation of your vines, playing a huge role in how they grow, handle stress, and ultimately, produce fruit. Whether you’re planting your first vineyard or fine-tuning an established one, choosing the right rootstock can set you up for success. We offer a variety of rootstocks suited for different vineyard conditions, and we’re here to help you figure out what works best for your site.
Factors to Consider When Choosing a Rootstock
Before selecting a rootstock, it’s important to assess:
Soil Type & Drainage – Some rootstocks thrive in well-drained soils, while others tolerate heavier, wetter conditions.
Vine Vigor – Do you need a rootstock that encourages moderate growth or something that boosts vine vigor?
Disease Resistance – Certain rootstocks offer resistance to soil-borne pests like phylloxera and nematodes.
Cold Hardiness – In cooler climates like the Finger Lakes, rootstock selection can impact winter survival.
Drought Tolerance – Some sites benefit from rootstocks with deeper root systems to withstand dry conditions.
