I have some catkins already yellowing that have not popped out anthers. The last 2 years one tree did this, but not the hybrid behind the barn, lots of pollen there.
Another board mentioned lack of calcium as a possible reason…does that ring a bell? All the trees with catkins on the pure species are at about the same stage of catkin elongation,
but one tree has them already yellowing, and the rest are still good and green…3 other genotypes. 2 of those genotypes are the same seedlot as the non shedding tree.
Got any ideas?
