We have recently found that a type of kernel rot, not associated with a mold or insect, is found in about 30% of the nuts from ‘Colossal’ trees when those trees are pollinized by Chinese chestnut....we strongly suggest keep Chinese cultivars from pollinizing ‘Colossal’. At this time we are not sure if this affliction will show up in all European/Japanese hybrids and if all Chinese chestnuts cause it. To be safe we suggest keeping European/Japanese hybrid and Korean (Japanese) cultivars 500 to 1000 feet away from sources of Chinese chestnut.
