New eucalyptus tree has strange leaf markings

[OranaGardener]

Hello, I bought a small eucalypt last year and it's grown quite quickly but its new leaves have this red blotchiness. It is very smooth, no bumps or spores. Do you know what it could be please?

Hello @OranaGardener 

Welcome to the Bunnings Workshop community. It's sensational to have you join us, and thanks for sharing your question about your eucalyptus tree.

It's possible that the tree is not getting enough water due to the brown ridges appearing on the edge of the leaf. Have you changed your watering habits lately? I'm a bit hesitant to diagnose it as a fungal infection as the leaf appears to be intact with no bumps, bruises or spores. 

Let me call on our experienced members @Noelle and @mich1972 for their recommendation.  

If you have any other questions we can help with, please let us know.

Thanks, Eric. I'm fairly sure it's not lack of water. In fact I was wondering whether it could be from over-watering?

Good morning @OranaGardener @EricL The red spots looks like a fungal / bacterial infection . Does your soil get really wet ? Too wet maybe ? I want to wait until @Noelle has a chance to look at this.

Hi Mich,

The soil is not naturally water-logged or even damp but I may have over-watered it by hand. It doesn't seem like a fungal infection as the leaf is very smooth. This morning I noticed that the newest tiny leaves are dying.

Hi @OranaGardener,

Do you have any photos of the actual tree? Are there other things that don't seem normal with the tree? On the branches or the trunk?

Can you take a photo of one of the older leaves next to a red one?

Do you know what species your eucalyptus tree is? 

Any more information you can provide will help diagnose the issue.

Hi Jacob,

My tree is a Corymbia - Flowering Gum, and is just over a metre tall. It's been in the ground for 11 months and has more than doubled in size in that time.

Here are a couple of photos of it in situ and a couple of it's leaves.

All of the new leaves are affected.
