A plum rootstock used for peaches, nectarines, apricots and almonds. This is a German Prunus domestica clone seedling rootstock, a patented selection is known as 'Weiwa®'. Most other plum rootstocks are based upon Prunus Instititia. This is very resistant to rootstock "apricot and plum decline" and is tolerant to Phytoplasma disease. Trees grafted with this rootstock grow to approx 3 to 4 m tall which is 20-30% less than myrobalan 29C which can grow to 6m tall.
