I won't put any negative ones ... Here are the positives:
I have been pleased with RollingRiver and RainTree. I'll email RollingRiver and get a response back within a few days (I do realize a nursery must be busy). RainTree has nice variety.
and think Ive gotten a couple items from OneGreenWorld, BurntRidge.
People have recommended England's Orchard & Nursery to me as well.

There is another garden site that has nursery reviews by customers called garden watchdog ....check it out (can't put web name here in GW it will block it)

For large trees stick to your source and graft on the varieties you want if you like them so much. Just hope they're selling you as much root as top.

I don't fault a nursery for selling only one root stock. Small nurseries have to come up with a business model that works for them and you choose the model that suits you.

I'm with Harvest. They can't carry everything. Even the big guys can have a limited to supply of certain things. I notice ACN sells out of a lot of trees even this early.

You can look at:
Raintree
BurntRidge
St Lawrence Nurseries
Cummins
ACN
Jungs
Millers
Starks Bros

I'll second RollingRiver- it's the place I check first. Though I don't think they have a variety of rootstocks. For that, Cummins is hard to beat. I had mixed results with Raintree (good berry bushes with huge root systems, but a couple of the apple trees didn't leaf out), but they were good about a replacement/credit and I'll be trying them again.

Check out the trees that Big Horse Creek Farm has currently - 4 rootstock choices and 350+ varieties. Great folks - I've ordered from them since 1999. If you can't find what you're looking for give me a shout, I do custom bench grafting every spring.

I was not faulting them for only one rootstock. I just needed to know what rootsotck they used and thought that their communication was kinda rude.

It turns out that I want a more dwarfing root than the M111 anyway.

Yes, I'll have to see how the trees that I bought turn out.
They sure are pretty. They are about 5-6 ft tall, but they are in pretty big containers, called "rootmaker/roottrapper" bags.

Thanks for all of the suggestions. I will buy some from my local but I want a Cortland and they do not have one.

Have had really good luck with my trees from Starkbros as well as some berries. Have had good luck with Raintree as well. The Cherry tree I purchased from Starkbros grew almost 5 feet the first year. Significantly better than our local nurseries.

AB which cherry did u purchase?

I went to our local very fancy nursery to check out their trees last summer, bought an Elberta Peach. It looked just fine at the nursery, got it home and planted it immediately. Within a week it was riddled with borers. It survived but I think for a while it was living a toxic waste dump of chemicals, to kill all the insects. It came with more pests than you can imagine, that were not visible to the naked eye at time of purchase. Also the tree was marked with a tag that said 'semi-dwarf' (as are all my trees) but no name of rootstock. I stick with Raintree. They have never let me down. They always confirm their rootstock and they have a great variety for a small orchard or large. They will replace trees if they are one year old or younger. Basically a one year guarantee. My orchard is small only fifteen trees but every Raintree tree has grown beautifully and fast. Good luck, Mrs. G

I've had great luck with Maple Valley Orchards and Nursery. They are a small mom and pop nursery but have hundreds of varieties of heirloom apples. It looks like they only use B9 and M26. I've ordered scionwood, rootstocks, bareroot apple trees and supplies from them for years. It's best to call and make sure they have what you want. Remember, they are a mom and pop shop :).
