recent purchase-some elm cuttings

[Dave E]

so after ditching the home depot jwp i decided to get these elm cuttings.
they're small but from the growth i've seen from my elm seedlings in one year-they won't be small for long.

i got 2 seiju, 1 corticosa and 1 yatsubusa they didn't come labeled if anyone can tell them apart i'd appreciate it.

my son spotted what he said is mold on one of them(i'm color blind and don't pick up on these things easily)
should i be worried about this?what should i do about it?

If I had to guess, I would say the middle 2 are seiju, but not sure about the other 2. Number 3 is definitely seiju. Get rid of the mold before winter storage, or it will spread to other plants. You can use a fungicide like Daconil or Copper.

As an aside, I like to treat all plants when I first get them for both fungus and pests, including in the soil, so they don't infect my other plants. I think it is just a good practice.

dilute lime sulphur is good now too.

From Facebook yes? Mark?

None of those look like corticosa to me....it is not a dwarf and should have much larger leaves. In my experience yatsubusa has a narrower leaf than seiju...but can still be difficult to distinguish from seiju.

yes

The first single plant pic looks like yatsubusa. The leaf has a peculiar shape compared to other elms.

thanks for the help-the 2 mids do seemed similar to me right away so i think stan may be right that they are seiju.

i just did a search on yatsu's and i see what you mean about the leaves.

so i'm guessing # 4 is corticosa
