Hey Ryan,
Cool to hear that you are thinking about an espalier project. Personally I think it’s a great way to go for a backyard (or frontyard) orchard.
If you haven’t checked out @HollyGates excellent threads on his espaliers, I’d definitely encourage you to do so. Like you, he has an engineer’s mind and approach to things, and his project is much better thought out than mine. (I would probably be the first little pig in the story, but the wolf hasn’t come to blow everything down yet, so…)
Personally, I’ve been really happy with the espalier approach. We have a fairly small yard that’s partly shaded by our house and large city street trees, so making the most of space and sun is a big thing, and I also feel like espalier makes the trees easier to take care of overall. I especially like the Belgian fence setup, because the individual trees are much easier to manage than a multi-tier espalier would be, but the cumulative effect is still equally striking. (And we get a lot of positive comments on the more visible fence in our front yard.)
In terms of updates, it looks like my oldest trees are now heading into their fifth year since bench grafting. We have not yet gotten fruit, though a couple of trees did have a few blossoms last year (Blue Pearmain, Hunt Russet, Wheeler’s Golden Russet, and Reine des Reinettes are the ones I remember). Reine des Reinettes started to form fruit but they didn’t mature. More of the trees do seem to be starting to form spurs, though, so I’m optimistic that we’ll start to get there soon - should know more in a couple of months.
I’ve also had better results on grafting since the first year (where I shot myself in the foot by storing my bench grafts in pots that drained poorly). Grafting in-ground rootstock works better for me, I think.
Here’s my current variety list with a few notes (again, no fruit yet). In keeping with the theme of the thread, I’ve noted the ones with MA/New England connections):
Adams Pearmain: On the less vigorous side but pretty well behaved.
American Beauty (MA): Has grown pretty nicely.
Ashmead’s Kernel: Declined after being transplanted out of the nursery and eventually died. Attempting a new graft this year.
Black Oxford x2 (ME): One of the stronger growers. Pretty striking tree: kind of like the fruit, the bark has a really dark purplish color. Have had a little trouble training it as a Belgian fence because it really wants to form a central leader.
Belle de Boskoop: Grafted last year, seems vigorous.
Blenheim Orange: Grafted last year, seems very vigorous.
Blue Pearmain (NE): I really didn’t think this one was going to make it the first year, but it recovered from its early struggles and is now a pretty strong-growing tree. Distinctive bark color, similar to Black Oxford but not quite as dark.
Bramley’s Seedling: Grafted last year, runaway freight train. Both Blenheim and Bramley are supposed to tend pretty strongly toward tip-bearing, so the plan is to grow them as freestanding trees and graft other, less vigorous tip bearers onto them.
Claygate Pearmain: Finally succeeded in grafting this one last year. Time to transplant it into the lineup.
Cornish Aromatic: Grew well initially but had a roughish year recovering from transplantation (I’ve ended up moving things around more than was good for them - one of those lessons learned)
Court Pendu Plat: Grafted a couple years ago. Not terribly vigorous. (This is one that I suspect I may rethink down the road, but I was in a “why not?” mood at the time.)
Edward VII: Grafted a couple years ago, and seems to grow pretty nicely. Pollination partner with CPP (both are supposed to bloom very late).
Fall Russet: Seems to grow pretty well but tends to get some kind of leaf spot towards the end of the season. (Not scab, I’m pretty sure - I think it’s Glomerella?)
Gray Pearmain (ME): Grows well, nice sturdy tree so far.
Hoople’s Antique Gold: Decent grower, generally healthy, but seems to be subject to the same late season leaf issues as Fall Russet. I know you were looking for this one - I believe I got the scion from Singing Tree, and there are other places that have it.
Hubbardston Nonesuch (MA): Botched the graft on this one a couple years ago and it’s struggled as a result. If it doesn’t come on stronger this year I will probably try to regraft it.
Hunt Russet (MA): One of my stronger growing trees.
Kerry Pippin: Grafted last year.
Kidd’s Orange Red: Grows well, healthy, seems to take well to espalier.
Mother (MA): In the middle with vigor, but healthy.
Old Nonpareil: In the middle with vigor, but very healthy.
Orleans Reinette: Another moderately vigorous but healthy tree. This is one that seems to respond to heavier heading cuts by bushing out into a lot of twiggy growth. One reason I have come to prefer notching as a much more reliable way to stimulate secondary branching. I’ve had an Orleans Reinette that was one of the best apples I’ve ever eaten. So good that I’m planning to graft another tree this year.
Pitmaston Pineapple: Very good grower, espaliers well.
Pomme Gris: Grafted a couple of years ago, transplanted last year, seems to be doing ok.
Pumpkin Russet (NE): This one has really struggled for me, partly because it got moved a couple of years in a row. Taking a wait and see approach on this one.
Reine des Reinettes: Another moderately vigorous but generally quite healthy tree.
Roxbury Russet x2 (MA): Kind of a tale of two trees here. One barely made it out of the first year, and while it’s survived, it’s been outstripped by the tree I grafted a couple years later, which has been a good solid grower. Out of the antique apples that we’ve tried, this was probably my wife’s favorite, and one of mine as well, right up there with Orleans Reinette.
Westfield Seek No Further x2 (MA): Local hero from Western Mass. Seems to grow well.
Wheeler’s Golden Russet (MA): Probably my rarest variety. According to Burford, apparently a sport of Golden Russet from nearby us here in Western Mass. Strong growing, very healthy. Had a couple of flowers last year if I remember correctly.
This year I’m planning to graft:
Ashmead’s Kernel (replacing the tree that died)
Orleans Reinette (adding another tree from my own scion)
St. Edmund’s Pippin
Windham Russet (NE)
Also growing some pears, but they’re not as far along. Current varieties:
Beurre Superfin
Comtesse Clara Frijs
Dana Hovey (MA)
Harvest Queen
Harrow Sweet
Honeysweet
Korean Giant
Magness
Tyson
Des Urbanistes
Winter Nelis
But a bunch of the pears got mauled by rabbits (snow was high enough to expose unprotected scaffolds - another lesson learned), so we’ll see what shakes out there.
This year I’m planning to graft:
Beurre Clairgeau
Cabot of Vermont (VT)
Louise Bonne de Jersey
Kind of second-guessing myself already on BC and LBdJ, but we’ll see how it turns out.
In general, I have had much more trouble with pears than I have with apples, partly due to pear psylla and partly due to the challenges involved in getting OHxF rootstock to establish itself. (In my experience, it does NOT like being transplanted.)
And we have one peach tree, Madison.
