Hello all!

I bought some field grown larch earlier this season and I'm having some issues. Theyve been slow to open thanks to our weather and late summer here in Toronto.

Now that they are showing some vigor, I am seeing some buds give out. I've had 3 or 4 buds turn a brown/yellow and die. You can see some needles also turning colour on some new growth that otherwise looks healthy.

Any info would be appreciated!

I had the same thing happening. At first everything seemed fine. Now it's dead.
In my case a major root disturbance killed it.
I should have kept it in the shade.

Not sure about yours, but it might be the same thing and you still have a week or so to take measures.

I haven't done anything major root wise. But I will keep it in a shared area for sure. Do you have any experience identifying needle cast?

Keep it in full sun, well watered. All day sun, or else.

Last repot was 2 years ago when they were pulled from the field

Where do you live ? What kind of larch is it ?

Those buds dying are not a good sign, on my Larix-x-eurolepis they're usually a symtom of root rot and most of the time, the whole branch dies. Since Larch resent being repotted when they're in full leaves, there's nothing much to do except watch carefully when and how much you water them.

My 2 €cents worth...

PS: and on your second photo, I think that the wire is too big...

Keep it in full sun,
Once again, what kind of larch is it?

From my experience, not all larch fare well in full sun in any environment.

My Dunkeld larch like 4-5 hours of full sun, not more. They suffer from sun scorch when in full sun and lose more lower branches than those in semi-shade : I don't live in the mountains where it is their natural environment, that's probably one of the reasons why.

It is a Larix Larcinia or American Larch

Then, I'll leave it to others to give you advice.

I know that some don't care a fig about scientific names, but what's a "cedar"? I mean, there are some common names in the US or elsewhere that don't mean a thing, like "my tree is sick, help me please". ;)

.....when did you wire it.....
Just as it started to open up for the season. I noticed its beginning to dig in slightly

Ya thanks for pointing that out. Advice without all the knowledge is really just a shot in the dark.

Sorry, my Tamaracks like full sun. And they live in swampy areas, too. You can have yours, I'll keep mine...

Did it by any chance get exposed to a late freeze? Nigel Saunders had that happen to some of his larch near you and had some buds die off. The tree has however put out some new buds and recovered. He showed that in a video a couple weeks ago.

Can we see a photo of the area it's growing in that receives "full sun"? I understand you use a "heavy" organic mix, but I was curious about the amount of sun exposure your suggesting.

Tamarack is the Algonquian word that means, "tree that makes snowshoes"
Very poetic in a way, thanks for the info.

I don't know anyone growing Tamaracks in France, or even in Europe : the few ones cultivated as bonsaï must be grown from seeds, that are available online.

Northern Michigan is lousy with 'em, but their southern limit is about 100 north of me. They do not like hot, humid summers. It is one of the most common bonsai forest subjects hereabouts, and the public loves them, too!.Tf FMG 2019_0325Meijer20190004.JPG
