Hellppp!!!! Yesterday it was fine!

[markyscott]

The soil was sifted with particles down to about 1/8 inch, but it may still be too water-retentive

Based on the pictures, it appears as though something is off a bit with your soil prep. I’m seeing a lot of fines on the soil surface that I’m not used to seeing with this kind of mix.

retentive. I have also only been using Peroxide/Daconil for about 3 weeks. Should I wait longer to see if it works, or should I have seen obvious improvement by now?

You’ll never cure the old leaves. That damage is done. But if it’s working, the new growth should be unaffected. But I suspect a root problem.

Based on the pictures

Are you referring to RileyJFDB13's pictures (the original tree in question? Or my tree in post #17? I did have some sphagnum moss in top of the soil, and some of the affected, fallen leaves on top of the soil as well. Last night, I removed as much of the affected leaves from the branches and cleaned the top of the soil as well as I could, removing all the moss and leaves. The newer growth currently seems healthy, but I will keep treating it to prevent the fungus from spreading. The root ball is very compact and I used a skewer to poke holes in it as much as I could. Next year it will go into a larger grow box with larger grained soil. I think I was also watering a bit too much, so watering will be reduced.

Sorry to hijack the tread. How did you treat your tree @RileyJFDB13, and is it looking healthy?

I may have gotten trees and posters mixed up. I’m referring to the original tree in post #1. This tree:


has surface soil that looks like this:


Which appears to have a much larger fraction of fine grained material than I’m used to seeing.


So I suspect it’s staying wet.

@RileyJFDB13, any updates on this elm? It is your only elm and if not, do any of the others have this problem? I have had something similar with all of my Ulmus parviflora the last 2 years. Last year I thought it was a nutrient deficiency, but the wierd mottled nature of the leaves didn’t point to the usual suspects. This year I noticed small black spots on some of the leaves and same discoloration. I’ve been applying spray fungicides and it seems to slowed it considerably. I’ll treat with a granular systemic fungicide and then fall/spring treatments before and during bud push to see if I can stop it next year. I’m still not entirely convinced that it’s not a fungus and deficiency. Here some pics from the last 2 years:

So I suspect it’s staying wet.

I have a "siberian" elm that has taken sifted 8822 and with Sphag, dirt, and winter turned it into a similair surface ratios...

I believe it is ALSO shedding water.

Which makes it double the funky.

I haven't done anything to mine.
Just observing.
Considering a repot.
And poker aeration.

Leaves look fine on yours, but the tree looks very weak.

Observing what? It's last summer?

How hot is it getting there @hemmy . It has been up to 120 here so far and I have got a few leaves that look like yours. My guess is the extreme heat in direct sunlight for me. The tree is growing like mad and is healthy just gets burnt leaves which I think is understandable.

Did you accidentally over fertilize? Those leaves look like what half my deciduous trees looked like two summers ago. All but a plum survived thankfully. If it doesn’t completely kill them they rebound well.

I don’t think heat is my problem, we average 70degF most of the year. Our unbearable heatwave this weekend saw high coastal temps of 88degF. I’m sure much hotter for Riley. I’ll post mine to a separate thread if hey get better or much worse.
