Just to be on the safe side should I spray my Swan Hill Olive® with Olive Stop or other chemicals to prevent fruiting?
The Swan Hill Olive® is rendered fruitless by a genetic anomaly unique to this olive variety. It has been observed that the Swan Hill Olive® is highly sensitive to spraying with Olive Stop, Maintain®, Ethereal®, and other similar products. Leaf deformation, yellowing and overall stunting can result from using the recommended rates for the European Olive and other trees. If you own Swan Hill Olives® and live in an area where olives are routinely sprayed for fruit and flower control, advise you landscape maintenance or pest control operator to NOT spray your Swan Hill Olives®.
