Keep doing what you've been doing to the other trees, but if you cange certain bonsai's location too quickly, it won't certainly like it so it'll drop it's leaves. If it's gone over two weeks with no new growth, it's probably died. Then you can collect one later in the fall. Do you have a pic?

I suspect that if you have regularly collected these at this time of year and have had good success in the past it has been because the trees have been in ideal health before you collected it. If you have had a spring and summer like I have here in Chicago it has been extremely hot and dry. Mature trees here are have been turning early for over a month and I suspect alot of our trees are going into a stress induced dormancy.

Your tree probably has the odds stacked against it for survivability. I say that with reserve though.

This past spring my club did a very nice presentation on collecting and while it is not uncommon to have trees survive being collected in the fall it may be more ideal to collect in the spring because as the tree emmerges from it's winter slumber both roots and buds are programmed to start growing and you really don't have to wait out a whole season or two to see if the work you have done has paid off.

Good luck to you. -G

Mrgreengenes, what kind of trees do you grow?

Chris,
Hi. Must be kind of funny for some one to come in throwing advise around and not doing any of the normal social nicietites that might help people gauge his creditablilty.... LOL.

I got into bonsai about three years ago while studying ornamental horticulture at a local community college in suburban Chicagoland.

I started off with ficus' because because the bonsai fascination hit in winter when nothing here is growing green. I still have the ficus'.

I then started reading and jumping into online conversations and showing my lack of experience in places like here about 2 years ago. Again lol. I try to limit my involvement still.

But about that same time almost miraculously I was able to pick up on some good advise and listened to some people about getting involved with some local bonsai clubs. And about two years ago I started looking for trees to collect out the landscape. Some are pretty cool. Others I'm not sure but I think probably continue to care for because you never know...

But The list of what I got is as follows:

Buckthorn-I took to the club last night and was so encouraged by someone I trust with experience and talent as ready for nice drum in spring!

Pin oak-I also took to the club last night for show and tell and recieved more encouragment for it's very real potential to be a very good bonsai in the coming future!

Boxwood-Large collected this spring and cut back hard but not hard enough. In a two person grow box some potential probably but I will probably need advise soon as to when I can cut it back hard again I'm guessing a couple of years to recover from the last cut.

Tropical hibiscus'- Tougher to work on then I initially thought. Mostly because the tree seems to put most of it's energy into flowering and I want vegatative growth. I spend alot of time pinching flower buds!

Caragana arborensence- A large collected tree that I hope to see become something. It will be a long long time before it is though. So for now it more for novelty.

Green ash- A larger collected tree. But again A long time before being any thing if it ever will be. It never quite got on to growing after I put it in a pot. But it is still alive. I would like to see it become a formal upright since it has some pretty good taper and basal flare but because of the size of the twigs.... Time will tell

I've got some others as well but all in about the same stages of development.

I won't go into the various tree's I have started from seed. They are long away from anything but my enjoy pure enjoyment of growing them keeps me doing it.
I also have a section of garden devoted to growing miniature herbacious plants for future kusamono.

I gotta go for now work is calling but I hope to get to know you more as well. -G
