How to Manage Pests

Pests in Gardens and Landscapes

Fruit doubling and spurs

Fruit is doubled when two fruits are fused together; when only one of the fused fruits is developed, the fruit is spurred. This disorder is caused by poor flower development as a result of late summer water stress during the previous year or of excessive shade.


Some varieties may be more susceptible to doubling and spurs than others.
