Pecan nuts rapidly expanding
At the start of nut enlargement, the seed inside the nut is small and heart shaped (like the Maramec nut pictured above). As the kernel expands, the seed coat expands downward towards the base of the nut and you can see two kernel halves start to develop (Osage nut above). Cutting nuts open at this time of year can give you a pretty good idea when nuts will ripen in the Fall (at least in comparison to other pecan cultivars). In the photo above, I've arranged the four cultivars in order of ripening. Osage ripens earliest, followed by Kanza, then Greenriver, and finally Maramec.
We may be suffering through the dog days of summer, but cutting open pecans in mid-July only makes me optimistic for a good pecan crop this fall.
