Good points Tree Spud. It seems to me that nurseries that have really good trees, are not that great a marketing. And nurseries that are really good at marketing, have trees that are not really that great. Cummins falls into the first category.
That said, I called Cummins last week and spoke with the person answering the phone (Alice). She sent me pdf list of trees/rootstocks for 2021. I called today and placed an order for what I wanted, finding that one of the five was sold out, so the list I received was not exactly current. Also, the list does not show what grades are available, so I had to select when placing my order on the phone. In my opinion Cummins has great trees, nice people, but marketing acumen… there might be room for improvement. Attached is the list I was working from as of Friday 12/4. (Yellow highlights are my preferred rootstocks, added by me, not them). Also, 2021 price schedule.
