I really like banyan style tropicals so in March 2023 I decided to give it a try. I bought two of these Dwarf Schefflera in 1 gallon nursery pots from the local bonsai nursery. I'm going to focus on the one I've done more work on since I have two of these. I haven't taken a lot of pictures until lately, and I'm basically learning from doing, and anything I can find on the internet. Any advice is appreciated, & opinions good or bad.

Picture from when I first got them.

I put the plant into a big clear plastic bag to trap the humidity so Aerial roots (AR) could form, I keep them under lights & take it out of the bag every 4-5 days to check on it, and let it breath. The AR began to form in a week and, then the weeks long growth process to reach the soil.

Here's a pic of the AR that made it to the soil in April of 2023 about 5-6 weeks from forming. You can also see some that dried up & died.

A week later I decided to direct these AR to were I wanted them with plastic straws (see below), using some moss inside the straws. I removed the straws once the AR hardened off.

I didn't take any pictures of it during the spring/summer while it was outside, but below is a picture in early September 2023 with the roots fully formed. I also completed defoliated it in late May of 2023, and that was a real nail bitter for me, hoping the defoliation wasn't going to kill it.

I just let it do it thing for the rest of they fall, trimming when needed. Fast forward to December 2023 I put it in a clear humidity tent that I could vent more easily, for more AR to form, but this time I misted the trunk and all the branches until I saw the AR forming. I now see the misting is the key. :) Below is a picture from February 4th 2023.

I just let them grow wild instead of using the straws to direct them like last year. Seeing all of these AR I cut the ones I didn't want off and let the rest harden off.

Below is a picture of it today with the AR hardened off, I now have a grow tent with fans and proper ventilation, so I don't worry about mold and fungus as much. My next step is to see which/how many of these AR survive, and to place them where I want when I repot this year.

I mentioned that I have two of these Schefflera, and this is just one of them. At some point, (not quite sure when) I want to plant both of them together to form a wider Banyan Tree. The second one is currently in the grow tent and instead of letting the AR grow wild I'm going to be more selective & direct more to the ground with straws.

The final goal is a smaller version of this.

Subject #2 today. Five weeks later most of the aerial roots (AR) have made it to the soil. Waiting for the AR to harden off so I can trim off the roots that are growing sideways off the main AR.

Still trying to figure out what causes the AR to grow like a tripod. I'll cut the two roots on the right off and just leave the one growing down once it hardens off. And you can see another root growing off downward one.

An example of the AR growing on green not brown wood.

I also found some weird growth on a few of the leaves. Nothing weird underneath the leaf. Might create a separate thread to ask the community what this could be.

1711222583248.png

I did find & remove some scale bugs a few months ago, and was wondering if these may be eggs, afterbirth, or feces, just speculation on my part. Trying to scratch it off just ripped the leaf. It's not sticky and doesn't smell, and nobody wanted to try tasting it.

I'm planning on repotting both Dwarf Schefflera together into a home made grow box in early summer.
 
This is awesome I just started to get into bonsai choosing a Dwarf Schefflera as my first project. Cant wait to these when you repot them.
Thanks! Welcome aboard. Glad I could be your first post. :) I'm fairly new so I'm either going to have a really cool house plant, or a maybe a decent bonsai in 10 years. I have a smaller one that I experiment on and it's a pretty tough species. Scale bugs love it.

I actually was planning on repotting it this weekend I need to deicide what kind of soil I want to use. Three weeks ago I decided on a front and chopped some branches off (no pictures of that) to make the look work in the container I'm going to use for a pot. It's going to be ugly in the beginning, right now I'm focusing on the aerial roots and keeping it healthy, I'll work on the branches a bit, but I'm going to hold off on defoliating it till next summer, although if it's doing well I may do a partial defoliation in early august. Plus it gives me something to do in the winter. :)
 
I repotted both of these in the same container today, took over four hours. Decided to skip the grow box and use a bus tub instead, to develop it in (idea stolen from Canjun Rider) . I used organic soil, as these prefer well-draining soil that's rich in organic matter and has a slightly acidic to neutral ph. I went with coco coir, perlite, & chicken Charlie's compost. Coco coir is soaking in a bucket (not pictured),

Bus tub last longer & has handles, I drilled holes and covered with screen.

Subject #2 went first. Plenty of circling roots.
1717364756577.png

I worked it pretty hard, it had a big tap root of sorts that I removed half of. Once it was ready, I planted it into one side of the pot before I started on the next one.

1717364830059.png

Subject #1 was next, root hook was a life saver as the rake got tangled too much, and chop stick seemed to take forever.

1717365322616.png

Crazy root hook killer strikes again, news at 11. :)

1717365465639.png

And now the adventure enters chapter two. If it lives I'm going to go in and clean up the branches, way to many of them and the crossing ones

All the aerial roots should thicken up this summer, and may make it nicer to look at. TBH I don't really like the way it looks now, but maybe in five years It'll look decent. 🤷‍♂️
I moved quite a few of the aerial roots and removed a few. Once again I'll see if it lives and go from there. :)

Some times things need to get messy before they get nice. 😆
Really nice job with this Progression by the way!
I agree & Thank you. Trying to create what I want changes constantly, second guessing everything because this is my first attempt...experience & knowledge with this species is coming first hand. Not to mention exposing myself by posting my attempt is the blind leading the naked. I have pants on. :)
 
Close to three weeks later and it hasn't skipped a beat, looks really healthy & I'm in the "I didn't kill it yet zone". Worst part would be if one side died and the other didn't.

The Bonsai Nursery I go to has an excellent Schefflera banyan tree that I admire. They repotted it last weekend, and I stopped by to ask silly questions & take pics. :) I didn't stick around for the final product but this is the before pic of it.

Just absorbing some experience and inspiration from the visit, & thought I'd share.
 
Tomorrow will be one month since the repot, and it's doing well. Looks like only one aerial root (AR) died, the shriveled up one on the far left.

PXL_20240629_225547907.jpg

It's getting new growth on the branches I chopped to make the two trees fit together.

1719703862667.png

So, it's alive and growing, and I noticed all the AR got a tiny bit thicker. I haven't fertilized it since the repot and with all the new soil I'm not sure if I should. What would I be putting in the soil that it doesn't already have? I suppose some fish emulsion wouldn't hurt it.

For now I'll let it grow while I decide my next plan of attack. Work the branches or partial defoliation?

I’m a fan! Really cool how they hang down and go into soil. Kind of spooky 👻

I use fish emulsion twice per month on all 60+ of my trees. It usually ends up being partial foliar feed since the foliage and apexes are quite dense at this stage in development, and of course it drips into the soil. All conifers responding beautifully to that plus the BioGold. I would assume deciduous like it too (?)

Thanks! :) I like the really big Banyan trees in nature where the aerial roots end up looking like different tree trunks of the same tree. Like this one.

1719707853368.png

This schefflera is tropical & I'm hoping not to turn it into a deciduous tree. :) I was just questioning the need for fertilizer so soon after a repot because I used coco coir & chicken Charlie's compost. Which makes me think the plant should have all the nutrients it needs for awhile. I almost tossed in some slow release BioGold but thought It'd be overwhelming the tree so soon after a repot.

Wow where is that group of trees?? 😮😮😮

Oh, I understand now, they’re tropical. 🧐 I know nothing about them. What you have looks awesome so far. Keep up the work!

That's in Maui it's the Lahaina Banyan tree lit up for the holidays. It's only one tree, not a group. :) The Lahaina Banyan Tree in Maui, Hawaii is 60 feet (18 meters) tall and covers 1.94 acres (0.78 hectares), roughly the size of a city block. The tree has 16 major trunks, in addition to its main trunk, and its canopy covers about 0.66 acres

its making a good recovery too!
 
Cambrian sensors? Nice. Tree looks rough & they took 40% off, but alive and growing is good. Wife & I were sitting under that tree in Feb 2022, crazy to see the photos now, & to know of all the homes, people, & small business around that area. :(
 
This Schefflera has been really heathy & the first Saturday of every month is free instruction day at Green Witch Gardens so, I took this up there this morning and got some free advice & instruction. It was awesome as I was the only student for about an hour so I had his full attention. I ended up trimming it into a dome shape canopy, & removing leaves in the interior. I didn't get a true before picture but here's a during shot.

The aerial roots are thickening up nicely.

This project progression is great! Very helpful for beginners with tropicals. I have 3 ficus cuttings picked up in May. Just strengthening the roots and focusing on growth for now.
This is very educational; thanks for this thread!

Thanks. It's been a good learning experience for me as well. :)
