Yes, I had really bad rot on my Euros this year, only the late ones gave good fruit. Thats one of the main reasons I got the Indar. I also removed several trees to give the ones left some better air circulation. Generally all Euro plums taste great if you can get them to ripen, so I don’t feel like I need a ton of varieties, just a couple reliable ones. I removed Reine Claude de Moissac, it was not as good as the other Gages. I also removed Purple Gage after waiting a dozen years for it to fruit (it is known to do that). Pearl may also need to go; it is similar to Golden Transparent Gage but the latter is more reliable for me. All the Mirabelles are going, they have never done well for me. Don’t worry, I still have 10 or so varieties left 
When I saw your Purple gage comment, it reminded me of a note I found last night when researching the July Green Gage:
Sounds like it has a lot going against it, if it won’t fruit for more than 10 years, or ripen any outside of a greenhouse.
Thanks Bob, I need all the rationalization I can get
I think Pearl is also going. I read up on it and it is known to be unreliable (as I have seen myself). Jefferson is another plum well-known to be stingy in fruiting, it has not even bloomed in ten years and its in a really sunny spot. Reine des Mirabelles blooms like crazy and then all the fruit drop on it. These two plums are “on deck” for chopping but get a few more years.
I really like ‘Sierra.’ It is quite sweet for an Asian plum (close to Agen) and has a unique flavor. It’s an Inca x Santa Rosa cross and, in my opinion, has some of the flavor traits of ‘Superior’. I doubt that it will make you tear out a Flavor King or Flavor Supreme but, for me, it was an easy choice to add it.
Thanks very much.Still have one? Brady
Oh man, don’t tell me that. Jefferson is one of my few single-variety trees that I grafted myself. I’m 5 years in hoping for fruit each year 
(on St. Julien)
The Yakima right next to it hasn’t fruited yet either, but a branch of it on a peach tree grafted later has.
There is hope. Ztom posted in the Plums of Maine thread that he got Jefferson to fruit (1 fruit) in year #3:
This is one I had near the top of my list, so I’ve been watching for mentions of it.
At the moment, I have a couple going into their second leaf after choosing to graft over a whole tree to the variety a couple years ago rather than just a branch. If the trees are big enough to take scion from, I’ll offer it on the scion exchange later in the year.
I was about to order a tree from the arboreum company, but due to security reasons, my virus protection would not even let me visit that page.
Is anyone having the same issues?
In the place where your web addresses are put in,type arboreumco.com.That should go to the site. Brady
Try a different browser. For me Safari doesn’t work but Chrome does.
Hey y’all,
I’m new here, but I figured I’d share my comments about the Arboreum Company. I am doing high density planting and they do have great, really vigorous trees. I ordered 2 pears (Packham’s Pride, Passe Crassane), 3 Asian plums (Inca, Elephant Heart, Mariposa), and 2 European plums (Pearl and Reine des Mirabelle, which they were so passionate about, they actually threw in on my order). They are very helpful and knowledgeable. Also, the trees are extremely vigorous. However…my peeve with them is the the website says all of their Asian plums are on Citation rootstock. But when I got them, turns out they’re actually on Myro 29C. I emailed them about this, but it doesn’t seem like they were interested in changing the information on the site. In our initial emals, they mentioned how no one had ordered any Mariposa plums this year…but the website said there weren’t any and this is one reason why I ordered one.
So let the buyer beware. Or email them to confirm. In the long run, it’s probably not a big deal, but I didn’t want to mix Myro 29C and Citation in the same hole. And as a newbie, I wanted to set myself up for success.
I will say that I’m really interested in ordering Howard’s Miracle and Golden Nectar for next year. I’m also sad to see the above comment about Pearl’s stinginess in fruit production.
One other comment about the Gnomes at Arboreum, since I’m about 30 miles from their nursery, they delivered to me at my house. I know they essentially do this as a charity to propagate “forgotten” varieties, and I think it was the very brusque Todd who handed off the trees to me, both times. I did get a small smile from him after the second drop off when I admitted I might have a small problem when all of my trees start to actually produce. Nice folks, but if rootstock is a concern for you, make sure you verify.
Hey Josh, good news on Pearl… I think it heard how its head was on the block and it has a mother lode on it this year! Jefferson is also finally producing. I’m glad I gave them a year or two more.
Well, I hope that means good things for me. They write pretty well and the Pearl sounds really delicious (even though I don’t have a lot of experience with European plums). After I read your comment, I was worried that the information about Reine des Mirabelle about “each fruit being a jewel” actually meant that there were so few fruits that they actually WERE jewels. Glad to hear you got a good set…I hope I don’t have to wait that long.
haha 
I should have mentioned that one above as well - it also set more this year. Its not quite yet to the point where I can fully see how it did but spot checks find fruit all over (most flowers are dropping but it makes zillions of them, only 5% are needed to stick).
Note that you will also have fewer problems with set being in California, plums set much better there.
Yes, plums, citrus, figs, and apricots seem to be the standard in my area. I am trying for a couple of peaches and nectarines, but mostly plums and pluots. Also, since I’m close enough to the Arboreum folks that Todd actually hand delivers to me, I’d hope I get similar results that they do. But this is the land of microclimates.
Josh, if grafting is your thing,check for wood here in the Winter.I may have some Howard Miracle next year.Brady
Oh, I think grafting is farther than I’m willing to go, for now. That’s a little too intense…for now…
