AusBonsai

Good evening everyone,
I have a Corylus avellana 'Contorta' which I have just potted up. I also have the oppotunity to pick up a largish one tomorrow. There doesn't seem to be a lot of information on them as bonsai. Unless I'm doing something wrong (possible) there doesn't seem to be much on here either. I am just wondering who on here has them. How hard can you root prune them. I have treated mine like I do all my other deciduous trees and so far so good. I've not really seen a really nice as a bonsai yet as people seem to just let the branches grow wherever they want to with no real shaping. I think with the right training they could make nice bonsai but will take a lot of work to get branch placement right.
Anyone have any issues with disease of any kind.

Thanks in advance
Josh

Only found these two worth a look ...

think we need some pics of yours I think a large one would be great (depending on cost)

Hi Josh,

I've researched on this species, Corylus Avellana for sometimes as I thought it could turn into bonsai. It has lots of different names, Deciduous shrub type, slow growing, branches break easily, hard to train, and die without any reason.

Is your tree grafted or grow on its own roots? I have one bush and grown on its own roots. I’m thinking of forest style.

It has no serious insect or disease problems, however watch out for Eastern Filbert Blight.
Lots of info you can find from US website. Search for Harry Lauder’s Walking stick

Cheers Ryan, some nice trees there. I'd seen the bonsai4me info but those other trees were nice. Unfortunately when I got there today I the large one I was after had been potted up into a terracotta pot and they wanted 3 times as much as it was worth. I ended up getting 3 smaller ones to play with. I'll plant one in the ground to grow on and put the others into grow boxes. My reasoning for the grow boxes is the trees I bought seem to have very large roots where as the one I had in a pot seemed to have have finer roots so I'll see the difference I get in growth between grow boxes to the ground and the difference in roots.
Here is my little tree. I haven't wired any branches yet. Some need to come up and others need to go down more. Here is how it started Here are the 3 I got today. I will start a thread on these when I pot them up and take some proper photos. I plan to split one in half and take air layers off the others later on to grow some more.

These are all grown on their own roots so all good there. I find the branches are ok to bend when young, haven't tried thick ones yet so will see when I eed to. As far as I know we do not have Eastern Filbert Blight here, I believe it's restricted to America.
Taken from here

Eastern filbert blight, Ansiogramma anomala is the most destructive disease of the
European Hazelnut and occurs only in North America. The disease became
commercially important in 1970, and is a major threat to the industry in Oregon.
Expanding cankers result in canopy die back, and death in mature trees. This disease
would have a major impact on the Australian industry, requiring expensive chemical
control. Cultivars range in their susceptibility to Eastern filbert blight, with Daviana
and Ennis being highly susceptible. Barcelona, Willamette and Lewis are moderately
tolerant, while the new release Santiam, is resistant.

Crop damage caused by pest birds, is a significant problem for many hazelnut
producers in Australia, and growers seek advice on how to address the problem.
Growing practices are changing, values for nut products are increasing, and the
geographical range of production is expanding. These changes often result in
expanding range and impact of pest birds

Also from the same site
The key disease in Australia is Bacterial blight Xanthomonas arboricola which causes
dieback of young twigs and branches.
This may explain the sudden dieing off.

Looks like I'll be playing with these and update info as I go.
