Title: Collecting Amur Maples
Post by: Michael T on March 12, 2011, 12:59 AM
While rummaging through a landscape nursery, I ran across these two Amur Maples.  They had been tossed aside and took root where they were left.  They were about 15 to 20 feet tall at the time of collection.  It took several hours to dig them out.  I needed a tractor to lift them into my trailer. The rootballs were several hundred pounds at the time of collection.

The first two pics were taken right after collection.

Pics of the nebari at the soil surface.  I will eventually expose more of the nebari as finer feeder roots begin to fill in.

You'll see why in a moment.

I left them alone (for the most part) during the first season.  Amurs grow like weeds.  But, I also left them in their collected soil, so I knew I needed to repot them this season.  John Calloway was kind enough to help me out.  It took both of us just to slide the pots over to a clear working space. 

Pic right before repotting.

Bare rooted.

I thought I built the boxes too big!  They are 30 x 24 x 12 inches and the stumps barely fit in them.

The finished product.  Planted in one hundred percent turface.  They'll be left alone for a couple of seasons.  Hopefully they'll develop the fine feeder roots I need to bring the nebari in closer to the trunks.  Will eventually reduce the trunks as well.  BUt, for now.  It's feed, feed, feed, water, water, water.

It's Callaway, and my chiropractor thanks you. :)

I'm excited to see how these two develop.  Lots of potential for some great, big trees there, I think.

What a tree.  What a find.  I just love amurs.  Lucky you.

Wow.  I think I got a hernia just thinking about getting them out of their old soil.   Looks like wonderful material though.

Bare rooted.

nice trunk and nebari.  2 most important qualities to have .  it can be really good bonsai.

but that is not bare rooted.  hosing root ball with water, it does not get rid off the material in the core under the base of the tree.
 you still have a lot mountain soil around the core.  it will become problem in the future.

do not cut off too much at one time.  it does not bud like trident maple.
have fun,
Boon

We got all the way to the base on bottom.  Next repotting we'll get the rest of the field soil out.  It will also be a chance to break out the reciprocating saw!  :)

Thanks Boon,

The nebari is actually pretty flat.  Well compared to where we started. Nearly all of the old soil is out, but there is still some that is going to have to come out the next go around.  

They need to develop more feeder roots closer to the soil surface and in between the larger surface roots.  I'll be picking on Callaway again in a couple of years hopefully to complete the rough work on the root mass.

I actually have a third one that I collected a year earlier and that is very similar. I personally think its nebari is better over all as its radial spread has no gaps.  It was harder to get out of the ground.  Needed a fork lift for that one.  I'll be repotting it some time this week.  I'll try to post pics of that process too.

Growing like a weed.  Some shoots had extended three to four feet and its still April.  I pruned the longest ones back.  Slow release fertilizer and liquid feed once a week.  They are planted in pure turface.  Nothing else.

I pruned the longest ones back.


Why?
Title: Re: Collecting Amur Maples
Post by: Michael T on April 24, 2011, 05:53 PM
Mainly because because the longest ones I decided to prune were suckers growing out of the base.

Awesome tree.  Have you given any thought to how you are going to style it?

Well,  I think about it,  but that's about as far as I've gotten.  All the growth you see now will likely be cut off sometime next year.  It gives a rough idea of a future look,  but I have several looks in mind.  For instance I really don't think the current apex is the right line.  I actually think lower one is.  Either way,  those decisions are still a long way off.  I'm really just watering picking weeds and feeding.  Mostly.

Here's the second one.  Seems to be a bit less vigorous than the other.  Also had a couple of trunks die back, but still growing pretty aggressively.  Haven't pruned anything off of this one.
