Learning about Japanese White Pine
« on: September 12, 2010, 09:45 PM »
Fellow bonsai enthusiasts, 

I'm relatively new to the bonsai world and I just joined bonsaistudygroup today. Since pines are my favorite bonsai subject(especially JWP), I started growing four 3" JWP seedlings, and purchased on-line one species(on its own roots). I'm relatively new to the bonsai world and since I hear JWP can be difficult, I'm scared that I'll kill it! Also, the information I find on the internet regarding this pine tends to be contradictory, or mainly applying to those living in warmer areas where JWP cultivation is more challenging. I live in New York City area(suburbs), the local climate is very similar to JWP's native habitat(central and southern Japan).
Is it safe to assume that JWP would feel at home in this area? 

Should I leave the pine exposed to full or partial sun? 

How often should I water it? 

What soil mix and fertilizer can you recommend? 

How does one care for JWP seedlings from their first year onward? 

Looking forward to reading everyone's comments! (will post photos after the tree arrives in several days)

Any photos?  From where was it purchased?

It might be worthwhile to update your profile with your location.

Also, welcome to Bonsai Study Group.

Thanks John for the first comment and the welcome!

Here are different angles of the Japanese White Pine. I the photo I took outside is depicts the needle color more accurately. I think this tree has nebari potential.

I purchased it from an online catalog (wavecrest nursery in Michigan). It was the only place where I could find JWP for a student-friendly price. The manager is fantastic and she said since many of their customers are "bonsai people", she knew what I was looking for. The tree arrived 2 weeks ago(Sept 15th) with its root ball wrapped in plastic. It's a beautiful and healthy tree, with lots of small buds all along the branches and lower trunk, and many white tips on the roots. roughly 18 inches tall, 1.5" trunk, about 11 years old.

I know early spring is the time to repot, but I had no choice but to pot it that day. What I'm mainly concerned about is the roots. I removed about 25% of the root mass, mostly large dead roots, and took out roughly 50% of the old nursery soil.

It's been in a cool shady spot for 2 weeks now, in a 3 gallon nursery pot. I'm using a mixture of 75% course turface, 20% regular bonsai mix (gravel, akadama, grit, turface, bark bits, and ecto/endo mycorrhizae spores), 5% decomposed Japanese White Pine needles with some extra white spongy mycorrhizal fungus that I collected under large Eastern White Pines in my yard.

My local New York climate is very similar to Japanese White Pine's native habitat (central Japan).
I'm hoping the tree will naturally acclimatize.

I love this tree and I hope it can recover quickly!!!

I would think repotting now it should be fine, so no problem there, though you might want to move into full sun.  Your soil mix sounds a little complex, and the needles and added fungus is rather unnecessary.  Native beneficial fungus will find you, with good soil, water, and fertilizer.  Also, I would think it would fine for winter in your area, with some protection.

How new are you to bonsai?  Any local clubs?

Thanks for the comment John, that's what I thought too! You've given me a little more confidence in my decisions thus far.

Yea, I thought I might have over done it for the soil. It's a mixture of having read too many articles and blogs, while acting in desperation to save my precious tree!! I've been in touch with a few bonsai pros (Brent Walston, Julian Adams to name a few) and all of them said that fall repotting for JWP is "the kiss of death". One of them even told me to literally "go to church and say your prayers."

If you call putting a $9 juniper purchased at a nursery into a bonsai pot and covering it with backyard soil and moss, then I started bonsai technically last fall.

I'm planning to join a bonsai club in New York called: Yamaki Bonsai. But I haven't been to any meetings yet.

All of my plants aren't even close to pre-bonsai quality. Ideally, I would like to have several trees at very different stages to work on (from seedling to near finished bonsai), but I'm on a student budget. This JWP is my first real investment.

What other steps should I take in helping my JWP back to health?

Put in full sun, water when dry, repot in spring after you start going to you Bonsai Club. Lots of folks ( look for Mike Pollack), look at their trees before you take their advice.
