Adcocks dwarf Jwp pinus?

[Adair M]

Maybe colander growing on the ground is a superior way to grow out trees?

Actually, no.

The purpose of the colander is to prevent long downward roots, and encourage a more compact fiborous root system by forcing the roots to backbud rather than extend. Allowing the roots to escape and extend defeats the purpose.

That is correct. My purpose was to see what I could get away with.

I reduced the trees down to about 24" tall and I repotted them all and sold one of them. I did this in late August and early September.

This likely can also be done in my special NW Pacific climate.

I have a 'large' Aoi on thunbergii that I twisted down last year, but I only half bare rooted late this past winter. It is vigorously pushing new growth and I'm planning to finish the removal of the bark laden nursery soil this coming Aug/Sep. BTW, it is in a pond basket set (upon two pieces of 4x4 cut on the diagonal) so the bottom is open to free air just like the sides.

Are your trees on their own roots or grafted? Onto p.thunbergii stock or p.sylvestris maybe?

Not completely if a decent fine root mass is retained in the colander while allowing a few roots to extend in the ground. It could work well. Just lift the tree up every year maybe. I dont think the tree would abandon all the roots in the colander in favor of the roots extending into the ground.


But I dont know anything for sure. Just an idea.


Brent does something similar except he uses standard nursery pots instead.

These JWP's are grafted and poorly, thus the affordable cost and my willingness to take chances with them. All of them are doing fine, not even a hint of shock.

Root stock species is not identifiable?

Root stock species is not identifiable?

I can only guess, but they might be Scots. The stocks don't seem grey enough for JBP's and they are a kind of tan like Scots.

I have a question pertaining to needle plucking/ candle pinching. Should I doing any needle plucking now? I think I understand how to balance the trees vigor by plucking more needles on the top and less towards the bottom. Some advice on how to keep this tree small and add ramification. I haven't really done anything this season except a few cuts. I would love any advice on proceeding with this tree. Here are some pics. You can see there are 2 potential leaders as well. Maybe one should be a branch or remove the bigger one al together?​

 

[Adair M]

This is not the season for doing any needle work ot wiring on JWP.

Wiring JWP is a September project as

 

[Adair M]

Don't pull JWP needles. If you need to reduce needles, cut them off very short with sharp scissors.

Thanks for responding Adair. Should I just leave previous years needles alone? ( I was reading Harry harringtons site and it was talking about needle plucking JWP. I'm glad I asked.)

 

[Adair M]

Usually with JWP, the old needles turn yellow and fall off on their own in Fall.

JWP is much slower growing than other pines. Generally speaking they need all their needles to get the strength to grow.

JWP are also notoriously difficult to make backbud. Yours, however, appears to be backbudding for you, which is great! Even needle buds, it appears. If you pluck needles, it destroys the buds!

It looks like your tree was cut back pretty hard. At this point, it just needs to grow.

This fall, around September, you could wire it. Until then, leave it alone.

 

[LeonardB]

Here is my remaining Adcox. I sold the others. There is a lot that needs to be done. I just started throwing some wire on it this morning. I don't know when I will get it done, I am faced with some problems here at home that require my attention.

Vance,
I would love to learn more about this Adcock of yours and whether we could talk about a potential long term lesson on its care and development ( perhaps I could take over some of the work for you? ) .
I am currently a member of the Four Seasons club and would welcome more discussions on the subject with you.
Regards,
Leonard

I would not do anything to the roots this time of year. It wouldn't hurt to pull weeds and remove debris off the surface. If water just sits on the surface when you water, just poke a few holes with a large screw driver a wiggle it around. This helps loosen the rootball just enough for water and air to get thru.

Don't slip pot it. Especially if you use good bonsai soil. You see, good bonsai soil is very open. Lots of air spaces. But, left alone, roots won't grow in because it's so different. Once in, however they grow great!

So, wait until next spring and do a proper "half bare root" repot.

Adair,
Thanks for the input. Spring will give me more time to learn how to care for it properly. I am hoping Vance will help me out at club meetings as well.
My only silver lining is that off everything done this year, none has resulted in dead trees.
Have to be thankful for that.

 

[Vance Wood]

I will be glad to help you if I can. The fact that I have kept mine alive as long as I have is miraculous even to me, they seem to be pretty tough. We can talk and maybe I can get determined to do more with the tree.

Thanks Vance.
I was even thinking about asking if you would consider selling it to me some time down the road.

Annual show in a few weeks!
Hope to see you there.

I may bring it in for the next meeting and let you take a look at it.

I look forward to it.

Mike,
Same here, I will be in my favorite Harley shirt as ID. I think we even met at last years show.
See you then.
