I'm looking to purchase 100-200 rootstocks for Peaches, Nectarines, Apricots, Plums, & Pluots, but I'm having trouble finding good rootstock for my specific conditions. I've been told to order super early, otherwise places will run out and cancel your order.
I live near the Willamette Valley in Oregon. We have 50-60 inches of rain a year which falls mostly in the winter and drought during the summer. The soil is very acidic before amendments (pH of 5 or so) and is a heavy silty-clay soil. The drainage is relatively good, but when it rains for 2 weeks straight, certain areas can get a bit waterlogged until it stops raining for a couple days.
After much researching, the rootstock that shows the most promise seems to be Krymsk 86 for many reasons including the fact that it works well with all stone fruit. Other candidates for my area/soil that are good for some stone fruit but not necessarily ideal for all include Krymsk 1, St Julien "A", Lovell, Marianna 26-24, Myrobalan (seedling), and Myrobalan 29C.
So far, the only place that I've found that definitely sells Krymsk 86 is Upper Canada Growers . They are currently out of stock, but I assume they will have more in the future, but who knows. Since they're in Canada, I wonder if that would be an issue.
Willamette Nurseries in Oregon has Krymsk 1, Myrobalan (seedling), Myrobalan 29C, Marianna 26-24, and Lovell. However, I've heard that there's no guarantee that you'll get what you order with this company if you're only buying a small amount (100 pieces is considered small) of rootstock.
Cummins Nursery in New York has Myrobalan, and Lovell and mention Krymsk (although I'm not sure which Krymsk they will be carrying (if any) once winter rolls in).
Dave Wilson Nursery lists Lovell, Citation, Marianna 26-24, Myrobalan 29C (though I'm not sure Dave Wilson Nursery actually sells rootstock, they may just list them as a reference for their pre-grafted trees).
Fowler Nursery Inc, or Sierra Gold Nurseries are both places that may be worth checking out. I'm not sure if they have them in stock, or their reputations as businesses; however, at least it's two more places that carry Krymsk 86 rootstock.
Personally for your situation, I would use the Krymsk 86 rootstock only, even if I had to wait an extra year or two.
Worst case senario, special order it from Cummins Nursery. Cummings Nursery is worth calling up, and finding out if they can order it in. From my understanding they will take custom orders, if the order is 1000 custom grafts or rootstocks. Since thats more then you need, see if you can do a co-op type buy, with several people buying together. You can advertise on local or regional classifieds like Craigslist or Permies to see if thats an option through networking.
Since you would be buying in bulk wholesale for a custom order, you could also sell some rootstocks retail, or do some custom grafting of disease resistant varieties, known to do well in the Willamette Valley region.
Those are my best suggestions.
