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).
One Green World has St Julien, Marianna 26-24, and Lovell
Raintree Nursery has Lovell, and Marianna 26-24
Copenhaven Farms has Myrobalan
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).
Fruitwood Nursery has Marianna 26-24
Burnt Ridge Nursery has Lovell, Marianna 26-24, and Myrobalan (seedling)
I would not recommend ordering from Rich Farm Garden Supply!
they get bad reviews
I will try to contact my local agricultural state university extension (Oregon State University (OSU)) to ask them if they have any recommendations on where to find specific rootstock like Krymsk 86.
Can anyone list some other resources on where to find stone fruit rootstock for Pacific Northwest (heavy clay soils with some drought tolerance and wet soil tolerance)?
Where can I find Krymsk 86?
Thanks :-)
