Rootstocks & Grafting

Rootstock

High soil salinity can occur through irrigation water, a high salty water table, or through extended use of potassium fertilizers. Vines in drought conditions will also have little access to water and thus suffer similar consequences as salty soils. Rootstocks that contain rupestris or berlandieri heritage are generally best suited to high saline soils as they take up little chloride, and they are also well suited to drought conditionbecause their roots dig deep in search of water. Josh Jensen of Calera Winery in Mt. Harlan, California, uses 110 R and 1103 Paulsen on his limestone and drought-affected vineyards. Barbara Widmer of Brancaia Winery in Tuscany uses 110 R in her driest vineyards in the Maremma.
