The Karls favorite is an excellent pollinator for warren. Many people have told me the difficulties that they have with this pear. Like most pears it is very easy to grow if we follow the rules and grow it with Karls favorite aka ewart as a pollinator. This one has callery for a rootstock. When you say it looks good that is a huge compliment coming from a fellow pear enthusiast. We collectively grow more pears than many research programs. There was a time when Nick Botner would have been on that list. A group has been desperately trying to save his collection. I’ve been reducing my collection from hundreds to around 50 - 100 types now. Im focusing in on fireblight resistant or ultra rare types of pears. @Fusion_power is rapidly expanding his pear collection. @scottfsmith like me i think is reducing his collection to his favorites and the ultra rare. He actually grows Champion a pear that often makes people wait 20 years on a pear. Im hoping to see many of these rare pears show up in the threads this year like champion. Many pears like champion aka Shannon literally have dissapeared from every source where information could once be found.
