The Story

The mighty Pecan is an American tree that has nourished both humans and wildlife here for thousands of years. It’s found primarily in the midsection of the country, where it follows the Mississippi and Ohio Rivers. In these moist, fertile lands, it flourishes, growing more quickly than other Hickory Trees (Pecan is a type of Hickory). Thomas Jefferson was a fan of Pecans. He planted several at Monticello, and he convinced his friend, George Washington, to plant some at Mt. Vernon as well. Uncommon on the East Coast, Pecans were known as “Illinois Nuts” to Jefferson.

The Details

Oswego is a newer cultivar that is grafted from the Greenriver Pecan and is also scab resistant. Unlike Grrenriver, Oswego has more of a rounded shape that can be seen when viewing a cross-section of the pecan. Maturing in late September, early October, Oswego will produce nuts with attractive shells and delectable nuts.

How to Grow

Just as Oswego Pecan appreciates low, fertile plains in the wild, it favors deep, rich, moist soil in the home landscape, too. It will undoubtedly survive in drier sites, but it will grow more slowly there. Plant it in full sun and give it lots of room. Pecan Trees can get quite large, and they live a long time—200 to 300 years! This is a hardy tree, tolerating winter temperatures to -20ºF, though it produces its largest crops in the southern states, where the growing season is long and warm.
