I have an old orchard dating back to the 1880s. About 40 of the original 150 full size trees are still alive but we are losing a few every year. I had great plans to replant the orchard until I discovered apple replant disease.
Specific replant disease - Wikipedia, the free encyclopedia
Anything I plant is stunted. I am not the type to treat the soil with chemicals and I have heard of a few rootstocks that are resistant but I don't know if they are available to the backyard hobbyist. They are also not full size as the original trees were.

The original trees I have were planted by ancestors and would have traveled by covered wagon. I have been able to save many of the varieties onto new rootstock and planted the graftings at various spots on my property but want to get the orchard itself replanted for family history purposes. Anyone with experience in this field?
