Cold weather and pecans
Back in 1989, temperatures in late December dropped to -27 F (-33 C). At those low temperatures, most trees suffered cold damage. During the fall of 1990, we harvested only 120 Lbs/acre (10% of normal) from our native pecan plots. Of all the cultivars we had under test at that time, Major, Peruque, and Colby were the only trees to produce a decent crop. Most cultivars and many native trees showed some terminal dieback while the more southern cultivars, such as Maramec and Mohawk, had major limb loss or were frozen all the way back to the ground.
