Starting up on a new house project this spring… yes building, moving… not far, just down the road a bit.
But I want to take my Early McIntosh apple with me. I planted it 20 years ago, got it from Starks, not sure what the root stock was… but the tree is 15’ tall and 16’ wide. I will post a picture of it shortly… below. I am sure I just took what ever root stock they offered… knew nothing about that at that time.
When I planted that Early Mc 20 years ago I also planted a Red Delicious… which died 3-4 years later of Fire Blight… and I planted a Fuji next… which died 3-4 years later of FB…
I tried starting several varieties of Pears during that too… all died of FB.
The Early Mc (cross of McIntosh and Yellow Transparent) never showed any signs of FB, and is only minimally affected by CAR. The only pollinator I have had for it for many years now is a crab, but it still produces some very nice apples.
I like the size and (how disease free) this Early Mc has been, and love the fruit. Wish I knew what kind of root stock it was on, so I could use the same to get it established at my new location. I would graft scion wood to that same root stock if I knew what it was.
I have a OGW catalog that list a few root stocks that they use… bud 9, geneva 935, M-7, M-26, M-111 and Antonovka (which is full size 25-35 ft).
It only mentions two of those as being FB Resistant (Bud 9) which is 30-40% standard size and M-7 which is 65% of standard size.
A full size tree is something like 25-30 ft… so a bud 9 tree would be quite small 7-9 ft… a M-7 could be in the range of 13-19 ft.
It seems like my Early Mc might be on M-7 ? Size wise it is 15 ft tall, which is about right for that. It seems to be too tall to be a bud 9. There may not be any way to find out for sure…
I like a 12-15 ft tree, NEED Fire Blight, CAR resistance… M-7 is also listed as being well anchored, widely adapted, winter hardy, resistant to FB, CAR, powdery mildew, and root collar rot. Per OGW.
A google search revealed that there are other root stocks known to be FB resistant, like G16 G30 G202 G41…
I would really like to take a piece of this Early Mc with me, and graft it on to a good rootstock to establish it at my new place.
I am sure some of you folks are very familiar with apple rootstocks - what do you think of M-7 ? and do you know of others that you think would be better.
FYI… I am in southern middle Tennessee, zone 7a. It has to work in the South East.
