Pecan pollination season well underway
In looking over your trees, remember that the color of the stigma does not indicate receptivity for pollination. Pecan stigmas can vary in color from green to yellow to orange to deep red. Look for the presence of stigmatal fluid on the flower. A sticky stigmatal surface means the flower is fully ready for pollination. Once the flower is pollinated the stigmatal fluid will disappear and the tips of the stigma will begin to brown.
