So I am working on this trident maple that was field grown. It is around 6 years old. towards the back of the tree there is a large space where a root should obviously be. I have heard of people drilling a small hole and inserting a root to fill up space, but I am new to everything other than keeping them alive. ha. What would you guys suggest?

Better pics of tree would help,i would ground layer the tree and say goodbye to that ugly base
I have never ground layered. Since the tree is still young I guess that would make the most sense. I am still very green to the Bonsai world. I have read tons and tons about everything from trunk splitting to air layering to organic vs inorganic soils. Even though I have read all that I don't feel any better at actually doing any of it to one of my trees. Really looking for advice from people that have experience with it. Thank you for the advice. I think that is probably my best course of action.

I'll have hundreds of bare root liners in Feb if you need thread graft doners.

I might take you up on it. Even though I have many years to go, the thought of killing any tree that is over 5 years old to make it prettier still irks me. Wouldn't thread grafting be safer than ground layering or am I backwards?
 
It depends. Root grafting will not kill the tree, but it will take years of drilling. Layering is faster and might give better result and you can shorten the tree. If the tree is vigorous layering would be my choice.
 
Tridents layer easily. A ground layer is easier than an air layer!

The key is make sure you cut deep enough when you remove the bark, so that it doesn’t just heal over.

Ground layering that tree would double its value!

You got time. If you don't feel comfortable doing it wait.
You could do other things until you build confidence. You can leave the layer for the last thing you do before it's ready for a bonsai pot.
I know they say get your roots and base in order first but it isn't graven in stone. A good layer almost guarantees roots all the way around the base. They can fatten up in the pot.

Reading is like watching a shower on tv, it looks and sounds good but you are still smelly. Stick to easy techniques at the beginning.

Try taking young seedlings, cut a small groove in the base where you want a root. Staple the seedling and wait.

Later, you can ground layer it.
 
Looks like a ground layer gone wrong once before.

Grafting is used to improve a nebari.
Not create one.
That's a mess.

You should put your location in your profile.


When it's time to layer...
Cut your new baseline at an angle that works best with the branching....taking care to avoid or include whatever is hiding in the back of this thing. (High root?) More scar tissue from old layer gone wrong?

Strip your bark and cambium as red.

Apply a cinch as black.

And the most important part.

Apply a RadialDisk. I used an eighth in rather ridged piece of shower liner...it could be a tile, an ice cream bucket lid, anything you can cut to shape to put at or just below the cinch, to keep your new roots growing outward.

Put the whole thing in the ground so that RadialDisk is just above soil. Then craft your pond basket, or colander around it with just an inch or so of soil, with a layer of sphagnum topper.

When the roots come out the side, you will know it is ready.
Heavy roots can be cut, thin roots can be directed into soil.

That way it's even when you dig it.

Successful use of this system on a previously potted elm.
Done as you will.

See the roots?

Now come spring....

All I gotta do is dig an inch down under the RadialDisk....
Wrap my $2 Baer Grills wire saw around there and get to pulling ....

Eff squeezing lemons!

So the cinch which is just tight wire or something is done above the stripped bark? For some reason I was thinking that roots would grow above the cinch. Thank-you for the clarification.
 
The goal is to completely remove the cambium layer which forces the tree to produce an entire new root system.

Check out this thread. I used a die grinder to make the layer...it was deep enough but should probably should have been a bit wider.

Just below the stripped part...

@ColinFraser has a good pic somewhere.

That red (stripped bark) above the black (cinch) in that picture is intentional.

I still think your making a mistake.
Not yet. I haven't decided what to do yet. I imagine Im going to practice on some younger saplings that won't hurt my feelings if they don't make it. It is quite overwhelming to see you guys with years of experience doing all these things and making them look so easy. I have always been able to pick things up very quickly and become proficient in a short amount of time. Bonsai is not like that for me. I am beginning to find out that after water, soil, and light....patience is the most important thing!

Try grafting seedlings into the base. It simple and will not kill the tree.
 
Fwiw, I've done scores of air layers and ground layers over the years... I read how to do them from a Bonsai Today magazine with pictures and went for it.... never killed a tree doing it and most of the layers were successful. Twisted trees is correct in saying that root grafting is safer to the tree, but in my experience, it's actually harder to do then the layer (meaning the graft might not take) and the results won't be nearly as beneficial to the tree in the long run. Personally, I don't consider layering to be an advanced technique at all, and it should be something even a newcomer shouldn't be afraid to apply to an appropriate piece of stock... not looking to get into a fight, just my 0.02. Good luck with whatever you decide to do.
