With winter in full swing, and my trees sleeping under a blanket of snow, my mind wanders to my tropicals and semi-tropicals sitting inside under T5's. I picked up a Bilobed Grewia (atleast that's what the tag said) at a local nursery here back in the fall. I nearly lost it to some form of leaf spot early on, but after a minor trim, defoliation and treatment with Nilnat (suggested by a fellow grower) it slowly bounced back, regained about 50% of it's foliage and started flowering... I'm assuming that it's a good sign.

The tree is in need of a repot. There's some old wire coming out from the base of the tree that was left behind from the original nursery. I tried pulling it out, but it's lodged, probably entangled in the roots. I plan on repotting it in the spring before it heads outside, and barring any unforeseen events, keep it there for atleast two seasons. It also requires some wiring and pruning, which will get done this spring/summer as well. After that, water, sun, fertilizer and Desmond Decker.

First of all, no one I know has any experience growing any species of Grewia, hence the post here. What kind of soil mixture would people recommend for it. I've heard anything from a simple black organic mix with pearlite will do, to full well draining inorganic. I'm assuming that a Bilobed Grewia is a Grewia Biloba. It has small 1/8" to 1/2" leaves with pale white flowers. Anyone know how much root pruning it will tolerate? Its in a nursery 4"x4"x"4" pot. I nudged it out when it was dry to see how the roots look back in November, and it wasn't severely root bound, but by the time spring rolls around it will definitely benefit from a trim.

Secondly, I'm not overly sure on style and front. I've been staring at it since I got it, and haven't done much to it, except remove a couple of branches that were disproportionately thick, and were crowding the crown. Turned them into cuttings. One rooted. One didn't. I want to keep the tree as a shohin. Any suggestions on front and style? I've attached a couple of images.

Thanks in advance for your input and constructive criticism. I've been reading posts as of late and some people have been getting overly sensitive. Don't worry I won't... I don't even think Smoke can make me wince. ;) although those shorts.. damn.

btw. I'm new here. So hi!

Cheers,

Mike.

Hey Mike.

I like 4 for a front.
Nice start.

Thanks Sorce. I'm torn between 2 and 4. Atleast with 4 the wire bite marks don't show. I don't know how long it would take, if at all, to have the tree grow those marks out. 4 also has the tree leaning towards the viewer... I was even thinking of pulling 4 down to the left a bit. The trunk seems fairly flexible and forgiving. I could probably even wire it into a semi cascade of sorts without any raffia/tape and not worry of it snapping. 2 on the other hand offers somewhat of an illusion? of taper but the top is leaning away to the back. And those wire marks. Decisions decisions. Luckily still a few months left before anything is done.
 
Even now that I see those wire marks, they don't bother me.
The pinched part right before the branching kills 2 for me.
It's less noticeable in 4.

Seems not all those trunks/roots? Would bend together without binding em. I kinda like the trunk movement as it is now anyway. Graceful, and putting the canopy in the right spot.

My first thought was taking the left branches down, with a little more movement. And getting rid of that rather "straight for a while" interior subtrunk.

Other than that, and chopping the whole crown back to about a 1\7. Ah yes ! A seventh! I like the broomish (touched to save!) style this is in!

I understand you're just gettin it back to good health.
If it we're mine, I'd wire it soon and take all the subtrunks back to a good branch or bud midsummer. 1/7ish.

I really like the odd flow of the roots, though getting the crown to follow the flow may be a challenge!

Yes they are just indeed roots that have been exposed for a while. My thoughts exactly on the "straight for a while" subtrunk. And chop down 1/7'th of the canopy or leave 1/7th? .. ... I'm assuming by cutting down each subtrunk to one good branch or bud, you mean I'd be left with 1/7th?

I see what you mean about the pinch as well..

Any thoughts on soil?

Thanks for the advice.

Mike.
 
The leaves on that looks a lot like Chinese Elm. You say it flowers so its not, but man it sure looks like an Elm leaf.

Hi @f1pt4 ; might you have any updates on this tree? I just picked one up myself and am curious whether you settled on anything in particular for the soil mix and, more generally, what your watering habits are like for it.

I showed it for the first time at a show. tbh, it was supposed to be in the "In Training" section, but it ended up on the shohin stand.

Soil is akadama, pumice, lava, fir bark, activated charcoal. Water normally. Do not let dry out completely. I've had dieback, quite severe actually because I forgot to water it for 3 days in the early summer. lost some critical branches.

Likes fertilizer. In the cold months i keep it under lights. spring/summer/early fall, outside all day.
 
If it's like Grewia occidentalis (lavender starflower) it likes fairly acidic conditions (5.5 or so) and if leaves wilt you will lose that branch. Well-draining soil and lots of light.

That's the one I had in the landscape, eventually succumbed to a fungus that is running rampant in the gardens.
 
It is a beauty little tree! As always, it looks much better in person. Tiny little leaves!
