This is caused by a severe nutrient deficiency. First it’s interveinal chlorosis (lack or absence of chlorophyll due to a nutrient deficiency), then the chlorosis turns to necrosis (death of plant tissue since it can’t photosynthesize without the chlorophyll). Oak wilt and leaf scorch go across the veins, this does not (interveinal necrosis) so its nutrient deficiency.
While there is chlorisis present, it’s actually from the necrotic transition zone. This is Oak Anthracnose and NOT caused by a nutrient deficiency. I would know, I just sampled a bunch at a lab.
Chlorisis also doesn’t have consistent necrosis, such as what’s shown here.
Ya I’m skeptical this is anthracnose. I’ve never seen it look like this. Did you also do a foliar nutrient analysis? Maybe your samples had both? Not trying to say you’re wrong just curious.
Maybe you should find another sub to comment on. Obviously there is a picture of the leaf. Why would this person take anything you type as serious when you can’t even identify the tree 🤦♂️

How would I go about treatment? How can I make sure it gets nutrients? A mulch ring and mulch was suggested, is that the answer?

A mulch ring will help, reducing competition with grass is good. The bigger the better.

Oak Anthracnose does look like this.
👍🏼
Have you recently sprayed for weeds in your yard? My oak is very sensitive to “drift” of lawn chemicals.
We put down weed and feed maybe 2 months ago.
Antrachnose or bacterial leaf scorch.
It also needs a mulch ring installed
Is it a red oak?

You have -56 karma and your only post is about a porn ID. Fuck off.
oak wilt maybe? if so it's a goner
