But in addition to being physically separated, the male and female flowers do not mature at the same time, which is called dichogamous flowering. Proc. Forkert’s pollen shed occurs well after the Kanza and Caddo nutlets are receptive. Pecan trees are not precocious, and it requires at least 5–10 years after a cross is made until the resultant hybrid can be evaluated (Madden 1968). If you prefer delayed billing please call (800) 733-0324 and place your order. In an orchard situation, having a few odd trees as pollinators will greatly improve yield.
