Thanks for the info and feedback
Marc replied today. He has only a single, large Foemina available right now (Foemina!).
I'll wait and see if Don replies. I'm also waiting for Todd Schlafer to let me know which of his RM junipers will be available after dormancy. I've been planning to write to Brett, too, as I had a great experience dealing him in the past. I saw a tree on his website, I emailed, it was available, I bought it. Todd does a great job of updating his available material, I will say.
Anyway, I can see why it's tough to keep up with inquiries... Not the primary source of income, other professional responsibilities, life gets in the way, etc... I do get it, honestly.
Beyond those factors, I can also see, putting myself in the position of such a vendor (specifically those who rarely update their website presenting what is actually available), that receiving an inquire like the one I presented ("Dear XXX, I am intersted in sourcing some quality juniper material, either relatively well-developed stock (but not styled) or finished trees....") I suppose I would groan and let it slide down the list of priorities.
Basically, as I see it now (especially after Adair made it clear that I can be vague when writing) answering an email like mine is opening the door to be pestered by requests to take a bunch of pictures of a potentially a large number of trees.
That could turn into a major time-suck, being asked to dig through the stock and take pictures, when in the end the vendor is only entertaining the interests of a "potential" customer.
I suppose if I ask for something very specific (Shimpaku, single trunk, twisted, live vein/deadwood, 2-3 jins, 18" tall, 3-4" base, 6-8" nebari) then it would be simpler.
But, honestly, right now, I am simply looking for "quality" material (i.e. material with very good foundations and potential).
I didn't know how else to phrase it when I reached out to these guys. I have no idea if they have 2 trees or 220 trees that they might regard as "quality juniper material, either relatively well-developed stock (but not styled) or finished trees."
Maybe you all (who deal regularly with Don, Brett, et al.) can help me more effectively interact with a potential vendor, because clearly I'm not sure how to source really good, high-quality stock material... When nothing appears on their websites.
Maybe, in the end, I should just take Adair's advice and buy some green mound from Brussel's!
