We’ve had lots of leaves dropping off pecan trees. This is brought in many residential calls associated with this also. Its an environmental effect of rain following a period of dry weather. We started out this season much like last season in terms of rain, and it shut off around June and through the Fourth of July. Recent rains have saturated the soils essentially drowning some of the pecan roots. In residential situations, leaves dropping is also a result of scab disease pressure. There is nothing that can be done about either.
