OTHER INFORMATION: This rootstock avoids drought because of its deep root system and does not do well on shallow, dry soils. It is a high vigor rootstock with low-yield:pruning weight ratios. Use of St. George should be avoided with small-clustered or loose-clustered varieties on fertile soils. Susceptible to nematodes and supports high populations of phylloxera. However, there are no examples of failure to phylloxera in the field. St. George leaves fold flat on themselves, shiny green and bean-shaped.
