Establishing early-ripening cultivars is critical for successful pecan growing along the northern edge of the pecan tree's native range. Over the past couple of months, I've photographed many cultivars adapted to northern pecan culture as they ripened this fall (25 Sept. 2013, 30 Sept. 2013, 9 Oct. 2013, and 21 Oct. 2013). However, ripening date is not the only characteristic that is important for assessing the adaptability of a cultivar for northern pecan production.
Today, I photographed a Stuart tree growing next to a Greenriver tree. As you can see in the photo above, the Greenriver tree has developed a nice yellow fall color while the Stuart tree is mostly still green with a touch of fall browning. Greenriver, like most northern pecan cultivars, starts to shut down earlier in the fall than southern cultivars, such as Stuart. This earlier entrance into winter dormancy means that Greenriver would be far more prepared to withstand a sudden blast of winter cold than the ill prepared Stuart tree.
