Growing Tips
Pecans are alternate-bearing (heavy crop one year, light the next); thinning clusters in heavy years can reduce this cycle.
Zinc deficiency is the most common nutritional problem in pecans — apply foliar zinc sulfate sprays 3-4 times during the growing season.
Plant at least two varieties for cross-pollination; pecans are wind-pollinated with protandrous/protogynous flower timing.
