I have not had any fb trouble with it but have only 2 trees.
I have a Ubileen that I planted about 17 years ago. I live in the PNW zone 8b
My experience…
Very disease resistant
Prolific some years…some not so…seems to depend on timing for early bees and warm enough for them to fly…
Ripen around third week in August and finished by about third week in Sept.
Yes to core rot. Taken me a long time to figure out timing for picking.
Pick when lifted and break away on branch.
Slightly green and soft to the touch at stem. If full yellow…rotten in center.
Best and highest use…dehydrated…sugar concentrates and results are like candy.
Jam and sauce excellent but again catching before core rot problematic… A bit of yellow and ripening on the tree is good.
They are not fast producers but everyone remarks the quality is good.
If you had to choose between adding Harrow Sweet or Ubileen, which would people choose?
I have a small tree I’m going to convert. Watching Nick Kasko’s videos, I noticed his young trees had quite a bit of rust, and asked which pear he’d recommend that is resistant. That’s where I heard about Ubileen.
I had Harrow Sweet penciled in for the location up until then. Perhaps I’ll find a spot for both, but which should I give preference to and why?
Currently fruiting I have Taylor’s Gold, Bell di Guigno, Seckel, and Thornley. With Golden Russet Bosc, Shroyer’s Sunset, and Abate Fetel down the road.
Current favorite from my yard is Thornley.
HS taste more or less like Bartlett. It fruits super fast and really has not had any problems for me (yet). I have Ubileen also. Has not fruited yet, but others have said it’s really hard to pick at the right time and the taste is good, but nothing special. Fruiting HS is a somewhat later variety while Ubileen is in the very early bracket.
I give high bonus points to a variety that is forgiving on picking time and keeps well. Plus plus if it can also ripen on the tree without rotting like Seckel and some others.
I think our neighbors have Bartlett, going by taste, and they are super bland. Grocery store Bartletts, and of course Jelly Bellies, are much better.
Bell di Guigno is early too. In fact, I think I usually miss picking them because they ripen in a window I’m not checking. I’ve mostly grafted over with Shroyer’s Sunset but left a little bit of wood for the pollen if nothing else.
In stonefruit season its hard for me to get too excited about summer pears.
