Select varieties that are resistant to pecan scab. New varieties of pecan trees were introduced when the practice of grafting together two trees with superior characteristics gained popularity in the 1800s. The pecan tree is native to North America, and most pecan tree varieties grow well from Illinois down to Florida and across the south to Texas. Pecan tree varieties known for stronger branches are more desirable for planting in a landscape because they require less maintenance. Most such hybrids are unproductive.
