Help! Treating this Siberian elm.

[Eckhoffw]

The Siberian elm started to get blotchy about six weeks ago so far I’ve just treated it with a mild fungicide (Citric acid based).
I was thinking it was brown spot.

Any ideas/treatments?
Thanks!!!

Does it not do that every fall?

Looks like autumn to me. End of summer, leaves are worn out. Up that way, the middle of September has near peak autumn color in some places in your state.

I’m not sure if this is autumn’s color.
It could be.
This is the second year I’ve owned it I don’t remember it looking like this last year.
I hope that’s all it is.

If it's not fall color, your tree is most likely dead, as what ever it might be would seem to have a pretty good hold on it.

It's fall, nothing more though.

You guys are probably right though
I guess the rust colored leafs alarmed me. There is newer growth that is deep green.
Just weird that none of my American elms are showing anything like this. But they are a different species,… so yeah. Thanks!

Hope this one takes off this spring!

Seems a total ph thing……. that is a complete volcanic substrate you’re using pH is everything as much as people say it’s not it is……. I get identical situations that look just like that when I forget to calibrate my pH meter every week I’ll look at the pH and it’s actually lower than I think it is……… it needs 5.5 to 6.5 …..no questions when using stones for dirt……..I’m a hydroponic professional.
It gets big-time cases of magnesium deficiency among other metal ions that are not able to absorb.

It’s always a surprise when this happens and I’m like darn?

I’ve lost entire crops to this negligence of mine.


Yellow blotches with green veins is magnesium, I believe.
I always use the deficiency link below, looks identical to potassium and magnesium deficient.

This makes sense. I’ve recently learned that in this region of Minnesota, we are on High concentrations of limestone. The tapwater I’m Using can’t be helping the situation.
I think I need to feed my plants better. Next year I hope to have my rain barrel set up.

Be sure to use fertilizer every watering with rain…………unless going organic cakes or something when using the volcanic aggregate.
The pure water will draw the nutrient right out of the roots……ph issues will speed the deficiencies in verry little time.

A ph meter and some ph up& down is perfect.

This one seems to be waking up fine.
I’m going to be watching the pH in the soil, in addition to using rainwater instead of our alkaline tapwater.



Thanks for everyone’s help!

This year……. Not waking up.
It showed a few green buds up top about a month ago. Those have dried up.


Today.
It was easy to pull out of the plastic pot. Lots of circling roots, but I wouldn’t say pot bound.
I broke the top branch & scratched a root to see if there was life. Branches are still very flexible.
Any thoughts or recommendations?

Siberian Elms are pretty tough. I would let
It ride. I would just leave it in the pot and see what happens later in the summer.
I trunk chopped this one down to about 2 inches in March and now(last week) it’s pushing five or six branches that have grown 3 inches in the past week

I recall another member saying that siberian elms hate to be pot bound and need a good working of the roots with each repot. Perhaps overdue?

Sorry about your elm man! Hard to tell from just a photo, but it looks like the soil is very dry. Also it’s a pretty large particle size for a relatively small pot which also leads me to think it just got too dry over winter. I had a Siberian elm for awhile and it was a water hog.

Fingers crossed that it buds out!

I had a Chinese elm take until July once to leaf out. I should have known a Florida grown tree would not appreciate Wisconsin winters the first year.

Thanks for your help!
Yeah, the particles are big. 1/4”+

It’s funny cuz thru the winter and early spring,
It seemed to stay very wet on top but possible was dried out below.

Luckily, there’s no shortage of Siberian elms around, so I will replace it next year.
