Title: fall repotting
Post by: Dirk on September 08, 2012, 02:14 PM
Last summer I got a small new JBP.
Its was grown in a pond basket for at least a couple of years.
Its growing in black, organic soil, which stays very wet a long time after watering.

If now is the time for fall re potting, I'd like to have a go at this one.
I would like to remove as much off the black soil as as possible, using tweezers and chopsticks.

I have a history of killing these trees, I don't want that to happen again. But I don't like the idea of leaving this tree all winter in its wet soil.

The summershoots are not yet fully grown.

Please advise me in this??

It looks healthy, I would leave it alone until spring. In the Bay Area we repot Back Pines starting in January- just need to do 1/2 of the root ball at a time. Might try Boon.

Thanks John.

I'm very sorry I'm not in the Bay area. When you are repotting your trees we are suffering severe colds and snowstorms. Last winter we had severe frosts till deep in march.

Our growing season is barely long enough for JBP.
Your refer to Boon's DVD's?
Do you know if the Boon DVD's are digitally available? Shipping to Europe seems to cost a Small fortune.
Stone Lanterns book on Juniper sold for $ 16,00. Shipping was $ 24,00!

You should check with Hans van Meer ( I am sure he is aware of your climate since he lives in the Netherlands too. He isn't a member of this board, but I do know that he is a member of the Internet Bonsai Club forum. Please note that I am NOT telling you to go away - just trying to be helpful.

Dick, sorry I had you placed in So. Cal, sorry about that, must be due to work brain..... Hans is a great guy and a quality artist, I think he is like most northern tier Europeans in staying away from JBP unless they have really good winter storage. Even more reason to protect the tree, repot when it starts to look like it is going to move in the spring and take in and out of storage as the spring progresses to protect from freezing.

I'm also sorry not to be in California! Its seems it never rains?...
I know Hans van Meer from his website, seen some of his beautiful hawthorns in shows. Seen him a couple of times but never had the chance to talk with him.

I'll just wait until April or even May before repotting.

Good timing is just as the buds begin to stir.

how sekibonsai always listen to the tree it will tell you when it time to repot and living in such a short growing season or severe winter maybe you should grow larch and the take quite the abuse
