Cold overnight temperatures slow pecan tree development
Cold overnight temperatures this spring have really slowed pecan leaf burst. At this point, I'm pretty sure our grafting season is going to be significantly later than normal. How late will depend on when we finally start getting warm overnight temperatures.
Kanza is a protogynous cultivar. Pistillate flowers on protogynous cultivars develop early in the polination season becoming receptive to pollen well before late developing catkins begin to release pollen. In the photo above, I've pointed out a Kanza catkin that is only now emerging. Most of the active new growth on this Kanza stem is developing vegetative shoots. Pistillate flowers will develop at the ends of these new shoots.
