Grapes

In the cool maritime climate of the Pacific Northwest, grafting grapes onto rootstock promotes can promote earlier ripening, sometimes as much as a week or 10 days earlier than vines on their own roots. Own root grapes are hardier once established as they can regrow from winter damaged vines.

Grape Rootstocks

3309

Our most commonly used rootstock. 3309 has a wide soil tolerance and lends early ripening to most varieties. Best performance on deep, well drained soils, 3309 also has low to moderate drought tolerance and relatively high tolerance for wet feet.

101-14

Performs well on heavy soils, has moderate drought tolerance and relatively high tolerance for wet feet. Good rootstock for low vigor varieties.

RIPARIA GLOIRE

Prefers deep, fertile soils, with low drought tolerance and relatively high tolerance for wet feet. The lowest vigor rootstock, giving the most compact vines.

SCHWARZMANN 01

A low vigor rootstock that prefers deep, fertile soils. Moderate drought resistance, moderate tolerance of winter wet. Good resistance to soil nematodes.
