JBP do not grow well, because it is not warm enough and the vegetation period is too short. But we have the native Austrian black pine, Pinus nigra. And we don't have collected raw material from JBP anyway.
many mediterranean trees don't grow well and overwintering is a pain: olives, Olea europea, Phillirea latifolia, Juniperus phoeniciana.
Californian junipers, fig trees.
Pemphis acidula and other Indonesian species.
and many other tropical and semi-tropical trees and trees of hot semi-deserts.
But we have many that thrive, just look at my gallery. I am not really complaining. I have too many anyways.
And I can grow very well: Ponderosa pines, Pinus ponderosa; Rocky Mountain Juniper, Juniperus scopulorum; lodgepole pine, Pinus contorta; all American spruces, and many others. It is a myth that these trees don't do well in most parts of America. After we have changed a few things. ponderosa and RMJ are doing very well in Harrsiburg, PA.
RMJ, Ponderosa and a few more:
1) very well draining modern substrate
2) water EVERY day, on hot days water twice, water VERY much, make everything including the trunk and the foliage dripping wet, use normal pipe water, can be very hard, as long as you dog drinks it.
3) feed every week to every two weeks throughout the vegetation period, feed much stronger than we learned, feed MUCH nitrogen, feed organic and chemical, forget totally about silly cakes, get your feed form the farmer supply or garden store, feed MORE than the prescription says, not less.
4) leave trees in full sun throughout the summer. Do NOT protect from rain.
5) place in the half shade or shade in winter, outside is fine, freezing of root ball is fine.
the needles get short when the tree has many more buds. Only a very healthy pine gets more buds. The more fertilized and watered the more buds. The more buds the shorter the needles eventually.
In the end only one thing counts: who has the densest ponderosas with short needles.
Look at my ponderosas.
Walter all those years of practicing bonsai has given you some fine , and healthy trees .
I would say that you are doing something right.
Not sure if you know it Harry but Walter has a fine collection here in the States too, don't know where though. But by the description of how to handle them, it should work anywere.
Two ponderosa pines normal size, the third one is shohin size. All watered and fed aggressively since years. So who is right?
I never questioned whether you were right or not, I don't have the experience you do. I was just questioning growing periods and if your fertilizing regiment will work in my longer growing season. I love the normal size trees, but the shohin doesn't do it for me. Wrong species for shohin no matter where you live, unless you cut the needles.
keep it green,
That shohin is an amazing one of a kind native american pine.....that trunk on that is beyond super fat!! That tree is amazing. Cutting needles on ponderosa is fine, many jbp needles get cut too....its just the name of the game when it comes to pines in development.
I will give Walter's advice a try for one season and see what happens. My advice to Walter for JBP won't work for him, too short a growing season, like he said.
keep it green,
Harry I think your commitment will need to a bit longer than one season to appreciate the effect.
Walter , could you confirm if the shown Ponderosas reside in your garden in Germany. If so can you give us a peek at the ones in Harrisburg?
LOL...say it ain't so!!!! ........ Congrats on the acquisition, should have told me I could have gotten ya a discount
We worked out a mutual agreement ! Nothing worth a crap is cheap and never will be.....
I will have to work on the Ponderosa's myself, Marco doesn't like them.
keep it green,
the trees that I showed are indeed in Germany.
Here you can see just a few of the trees that I have in Harrisburg; PA: http://walter-pall.de/American_Pines.jpg.dir/.
Since I am only there once a year they cannot look as good as the ones in my garden. From April 22 to 27 I will be at Nature's Way Nursery again to work on my trees together with students. There are still some openings. I will have lots of new trees then again.
