(For a specific recommendation it is advised that the grower consult the nursery providing the vine). In general; all of the following rootstocks perform well under a variety of circumstances: C-3309 – (Reduces vigor & can enhance winter hardiness due to early ripening. Well adapted to wet soils.) SO4 – (Does well in shallow, poorly drained, wet soils. Offers good resistance to nematodes as well as drought.) 101-14 MGT – (Well adapted to wet soils.) 5C – (Well adapted to clay soils, offers very good resistance to nematodes.) 1616E – (Exceptionally resistant to drought.) 18-815 – (aka 1899 Castel -very little research available.) 5BB – (Well adapted to wet soils, low relative vigor and above average resistance to nematodes.)
