What is this growth?

[cornfed]

It's a Chinese elm. Seigen if it matters.

Damn that’s freaky looking! Does it move?

It doesn't. It's kind of sticky.

It’s a scale insect.

It’s a scale insect.

A guy from my local club suggested insect as well. I'm going to spray some neem oil on the trees.

You can also remove it physically, and ladybugs prey on them.

Third the scale insect

a Chinese elm. Seigen

What does an Ulmus parviflora 'seigen' look like? Never heard of this variety

 

[rorror]

Perhaps also spidermites?

I horribly mispelled... It's "Seiju." https://www.gardenia.net/plant/ulmus-parvifolia-seiju

Not mine


Mine.​

All I know is what I was told from the club member who sold me the cutting. It's a dwarf variety of Chinese Elm that is somewhat hard to find. Very small leaves. I plan to make cuttings out of most of the branches higher than five inches or so.

I haven't added it to my "Cornfed Edition" bench on the Nut here yet. I have several more to make threads on when I have time.

Sidenote: He also sold me a Kashima Maple cutting, that's the middle tree in the photo above.

Neem oil as well? The label said to do it in the morning or evening, so I was going to spray all my trees this evening. Some other ones have small bites in the leaves and such.

No need to spray neem oil. Just remove it by hand or tweezers.

Do y’all find the dish soap water concoction to be effective?

It is what I use as first line of defence (Well, second, garlic poweder in the soil is nr 1).
If they break through I might use poison.

I mix a spoon of soap with a shot of alcohol in a litre (1/4 gallon) mister and soak the affected areas.
