Japanese Black Pine longitudinal study; Collaborators needed

[Elmar]

Yep,

all good hear on a PC with windows 8 Grant

Good,

I will find out when I email out or PM who has Apple and who has other.

Grant

G'day Grant we have a Mac and usually have no problems sending PDFs.
If I may, try this:
Hold the "Command" key and press the letter "P".
In te drop-down window, at the bottom left is a button labelled "PDF".


If you click on it, you can then save as a PDF or Mail PDF (there are other options, but I don't use them).

Hopefully I haven't tried to teach you how to suck-eggs ... If I have, my apologies.



Cheers

Hi Grant, like to help out, don't have many JBP's because the growing conditions here on the Tropic of Capricorn (Rockhampton Qld) are somewhat challenging with the humidity and heat of summer and next to no winter. but will do what I can to help.

some of our pines

How long did you have hem for...We are at almost the same longtitude...I would love to see how yours will do, and have done up to now.
I keep mine in the shade...30% net...how do you keep yours?

Hi all,

Those of you who are helping with the JBPTrial and coming to Bonsai By The Harbour should say Hi on the day at BBTH and we could all have a quick get together on the balcony to say Hi to each other.

grant

see you there

I have visited Rockhampton once and it was beautiful and hot and humid.

I will also be interested to see how pines there and in Cairns perform. I am told JBP do grow in Cairns so I imagine with the correct techniques and precautions JBP should do well in Rocky.

Lots to learn from this study Grant...I know there are some people growing pines in Florida...but very few and in isolated areas of colder weather. Yesterday some of my trees went into a deep freezer for dormancy. The white pines and few deciduous.

Do you, like Bill Valavanis of Rochester New York, keep them at around -2 degrees?

He doesn't need a freezer; he heats to -2 degrees and it could be - 10, or -15, or -20 outside.

It is an old freezer so it does not freeze too much...plus I leave it little bit open on one side. I am trying to keep them cold so they get the dormancy they require. I keep them for 3 month at around +-3C.
Palmatum Umemodoki, and few other trees,does not do well here...so I rotate them every other year I give them dormancy...Some I give dormancy in summer...in the same manner.
I noticed some trees realize it is spring here...some dont. so I have to do it according to how they behave. Some are behaving as if spring has just started here...those I plan to make dormant when they start behaving as if it is autumn...or at least those are my plans.
I shall just have to see how it will be...I have more thanone tree per variety so I can experiment with that.

Hi all,

First reminder.

For those of you participating in the trial and have selected 2 pines and labelled them no 1 and no 2; If you did the first fertilising on Pine no 1 around the 1st of June; it is now time to do the second fertilising..

If you are about to experience days of rain(forecast for Canberra) it is probably best to delay until the rainy period is over; so I will fertilise; according to the weather forecast; either Sunday or Monday. This way the fertiliser is not flushed out of the system immediately.

A few days variation here or there won't affect the trial.

In 2 weeks time I will ask if there is any observable differences between pines no 1 and 2.

Cheers.

Rain forecast for Wollongong over the weekend as well so I will wait until Monday as well

Grant I fertilize every week with half strength. Is that bad? Should I change?

[Grant Bowie]

Grant I fertilize every week with half strength. Is that bad? Should I change?

It depends on half strength what?

Half strength 4% NPK = 2%
Half strength 10% NPK = 5%
Half strength 18% NPK = 9%

if you see what I mean.

What do you use and at what strength?

Grant

[Neli]

I use one week manure water with kelp extract and another week 20 20 20. at low dosage.

So half strength 20 NPK?

If so that should be OK.

Just re read your climate info and you probably would benefit from frequent ferts over a longer season; so you should be fine.

You might consider higher levels of ferts in spring to build up vigour for the new growth ; then back off again after full candle removal.

JUST A SIDE NOTE>

Last weekend at Bonsai By The Harbour during my Pine workshop I asked the audience who does full spring candle removal (at all).

Only about 25% or 30% said they do so; so there is still along way to go for Pine techniques in Australia.

However i think it is getting better and this trial/study should help.
