Pinotage has an inherent adaptability and the capacity to produce high grape yields under ideal cultivation conditions. There is now an established knowledge base on how to grow Pinotage vines successfully, and as such, the Pinotage producer is fortunate to have various options when choosing alternative cultivation practices, with yield control measures that will ensure an optimal crop.

CHOICE OF ROOTSTOCK
As far as is known, Pinotage has no affinity problems with any of the well-known rootstock varieties. The choice of rootstock variety will therefore mainly be dependent on the soil type and the availability of water. Rootstock varieties that include moderate balanced vigour under supplementary irrigation or dry land conditions should enjoy preference.
Rootstock varieties that include lush growth, e.g. Ramsey, should be avoided.
Under dry land conditions preference should be given to R99, R110, Paulsen 1103, 8-7USVlT and 140 Ruggeri. Under supplementary irrigation conditions rootstock varieties such as R110, 101-14Mgt and 8-7USVlT can be considered.
