General Comments:
99 Richter is suited to a wide range of soil types, but not wet, poorly drained situations. Scion varieties grafted to this rootstock may develop slowly but will deliver consistently good crops. Drought tolerant but moderate sensitivity to soil salinity. Performed well at Wahgunyah, Victoria and in the Barossa Valley.
