Those of you considering
variety and rootstock selection for apples might get a kick out of some
numbers from our three-year-old apple espaliers. These trees were all
grafted by me in April 2014, then they
were set out into their forever homes that fall. Here's the data:
Based on this data, I
suspect that M7 rootstock isn't quite cold hardy enough for our farm,
at least not if I plant up against the hillside where very little
winter sun hits. On the other hand, I wouldn't be surprised if the M7
Winesap is an early bloomer because of its rootstock (as opposed to the
Early Harvest, which is noted for precocious bearing).
Honeycrisp, if I recall
correctly, was hit hard by cedar
apple rust last summer. I think I meant to pull the tree out,
actually, but it was granted a stay of execution until this year.
That's a variety problem not a rootstock problem, and despite how much
Mark loves the apples, I wouldn't plant a Honeycrisp again in a
no-spray orchard.
The other varieties seem
vigorous and happy. Maybe next year, even those on MM111 will bloom!
Nice! Have you had any problems with Cedar Apple Rust? I've had tons and someone suggested getting pears instead. Then the extension service said pears get rust as well. I put in two pears, two plums and, based on one of your online references got a combination red and golden Delicious. The last doesn't appear to be doing as well as the others as it's just now starting to leaf out, but it is early in the season.
Which one of your experiments do you think you'll continue and which do you think you'll kill other than the ones that are already dead?
