Each Pecan Tree Is Unique

Pecan trees should be selected on the basis of nut production, nut quality, pecan scab resistance and susceptibility to phylloxera. Some trees remain in the orchard for years without producing. Other trees consistently harbor pecan scab and the pecans never fill well. The strength of the foliage is important but does not always indicate the productivity of the trees. Certain trees within an orchard are infested with phylloxera year after year. A special spray program may be required to make them productive. If other trees will fill the spaces, phylloxera-infested trees should be selected for removal over otherwise comparable trees.
