You reached out privately, but I’ll fill you in on Meehan’s here for the benefit of all.
They have a ton of everything, and much of it is beginner to intermediate stock. The San Jose they have there are worth a 7 hour drive. If I didn’t want to focus on deciduous, I’d buy up most of them.
There are some larger trees they don’t bring to shows that are worth looking at, and every year they dig up a few species from the growing area.
Having worked with them for about 7 years now, I’d say they have the cleanest tropical stock you can get. This matters. They are also doing this full time, and don’t focus on finishing trees.
What if more of us in the industry specialized? Perhaps better bonsai shall be created?
