White Pine Bonsai Discussion / Re: New JWP help needed please..
« Last post by oli14 on July 20, 2017, 06:05 PM »
First post on here..

I've received a young JWP bonsai, it is about 20cm tall and is semi trained (pics will follow tomorrow)

Basically it's has come in a small plastic pot and is planted in what looks like standard planting soil and not a proper bonsai mix..

My question is, would repotting into an akadama mix at this time of year be detrimental to the tree? 

Thanks,

Oli

General Bonsai Discussion / First ever Pruning of first ever Bonsai
« Last post by GingerPunk2 on July 16, 2017, 01:24 PM »
Hey there lovely people.

My wife recently decided to buy a bonsai. And I've kinda taken over after reading and watching many many videos on the YouTubes.

We grabbed a larch pseudolarox amabilis from a local garden center. I've since been watering and fertilizing the plant. And it showed great growth over the last couple of weeks. As its early summer here in UK. I read on countless threads about the importance of pruning and shaping and to do it early on. So I ordered some tools and gave it a haircut this afternoon.

It was a little nerve wracking to be honest. And I was daunted about doing anything that may damage the tree.

I also found that it was difficult to try and see the shape of tree that I wanted etc.

So I really took my time and removed a lot of branches that were either crossing over others or ones that seemed to make the tree look cluttered.

So I am posting some before and after pictures here in the hope of some more seasoned folks opinions and thoughts.

Did I cut off too much? Etc. I have some wire arriving in the next couple of days and will begin to try and shape the tree for a bit more style. So again advice on anything that you peeps may think would work or look great would be heavily appreciated.

Thanks all

I like were this is going. As usual, I'm away for the summer and only have occasional internet service.
ut I had too put in my 2 cents.....coming along nicely for sure.

I repotted it again this spring and finished replacing the old soil. It seemed healthy enough to decandle and needle pluck so that's what it got. I'm still not thrilled by its vigor, so I'll keep chasing after that.

(I tweaked a few branches this morning upon seeing it in better light. )

General Bonsai Discussion / Boxwood blight
« Last post by snipologist on June 30, 2017, 04:55 AM »
Boxwood blight is an uncurable and fatal fungal disease that affects many types of boxwood.  It has been detected in several states and has now entered the north eastern part of Illinois.  Due to this serious threat The Chicago Botanic Garden and Morton Arboretum have banned boxwood bonsai from being shown in bonsai shows held in these locations.  Vendors may also not bring boxwood to sell at the shows. 

It would be good for all to check for this disease on any boxwood in their collections.  Here is a link for more information on the disease.    http://www.midwestbonsai.org/boxwoodblight

Deciduous Bonsai Discussion / Corylus avellana contorta
« Last post by msudholt on May 13, 2017, 09:10 PM »
Have a Corylus avellana contorta rubra.  Developing nicely into a semi-cascade but the leaves are large.  Does anyone have experience reducing leaf size in this species?  Does it respond well to defoliation?

Japanese Black Pine Bonsai Discussion / Re: Dothistroma & blight
« Last post by 0soyoung on May 05, 2017, 06:43 PM »
My view is that you should remove all the older needles, even ones that seem unaffected, keeping only the needles from this season's growth. Pine needle fungi are inside the affected needles - that is why there are visible effects. Keeping them only invites the formation of fruiting bodies and the release of spores to infect anything nearby. The objective of spraying is to kill the spores, IMHO.

I have been fortunate to have never had a serious needle blight type of issue. However, I spray a peroxide solution anytime I see anything I suspect to be a fungal issue on any of my trees. I prefer to leave Daconyl and the like as the nuclear options. Consider trying 2 tablespoons of 3% hyrdrogen peroxide in a quart of water. It is an effective broad-spectrum fungicide as well as anti-bacterial AND is very eco-friendly (H2O2 --> O + H2O; the reactive oxygen does all the work) ... periodic spraying at fruiting times.

Bwaynef, thank you for your reply!

I am pretty sure it is one of the blights -  Dothistroma has caused many problems with commercial pine growers here in SA and it is listed as the main culprit (along with cast) causing trees to suffer/die.  They don't really spray or treat in commercial growing because of high cost.  They rather chop the trees and let the ground/soil recover by not planting for a few years. But copper fungicides is what they list as treatment.

Not touching needles and start spraying in spring...this is what I have done last year! Didn't touch the tress but had a rigorous spraying program in place starting in winter  (lime sulphur, Chlorothalonil, copper fungicides) all the way through to autumn... no success. 

My thinking was to rather stress the trees now (autumn) and to eliminate fruiting bodies infecting current year needles.  Have the winter dormancy for recovering and (hopefully) no or very little spores in spring... in theory!!!

I did read on a well respected bonsai website that blight/Dothistroma can NOT be cured but rather managed by removing infected needles as soon these show signs of infection - hence reducing the likelihood for the pathogens to spread.  BUT if once infected you will not be able to get rid of it.  Can anyone confirm this???

For now my plan is to use higher concentrations of the copper fungicides and spray in shorter intervals. 
Well, I guess this is the only choice I have...
