Pecan 'Oconee' problems — and how to fix them
Pecan 'Oconee' (Carya illinoinensis 'Oconee') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Pecan scab
The major disease in the humid Southeast, scab spots nuts and leaves and ruins crops in wet years. 'Oconee' has moderate tolerance, but airflow and fungicide programmes may still be needed.
Needs a pollinator partner
Pecans are dichogamous, shedding pollen and receiving it at different times. Plant a compatible cultivar of the opposite type nearby so flowers are pollinated and nuts set.
Alternate (biennial) bearing
Heavy crop years often follow with light ones. Thinning, balanced nutrition and consistent water help even out yields over time.
Zinc deficiency
Pecans are prone to zinc deficiency, seen as small, rosetted, distorted leaves. Apply zinc to soil or as foliar sprays where leaf tests show a shortfall.
