I have 2 branches that look weird like they are loosing their color. The rest of the tree looks just fine. Should I just trim it off or is the tree telling me it needs something? At first I thought water but the leafs feel nice and wet so I think we are good with water.

It's good, no big deal.

The leaves are showing classic symptoms of overwatering: green veins with yellow panels.

I was wondering what the physiological basis of the yellow panels. Could it be an indication of some sort of osmotic imbalance?

Richard

Due to overwatering, the roots are unable to uptake nitrogen. Servicing of the leaf panels is the first to suffer. The symptom is often referred to as chlorosis -- a lack of chlorophyll in the leaves. An inexperienced or greedy nursery will sell you an iron supplement to "fix" the problem. Iron chlorosis is a serious problem in alkaline soils and certainly I sell a lot of iron supplements to gardeners in the Great Basin region of the U.S. For this peach though, the problem appears to be over damp roots.

That's not what I expect, LoL
With the soil misters the soil is dry to the touch, I'm worried if I back off on the water that some of the other plants on the same zone might start to suffer. I forget the peach does not like as much water as some of the other plants. But on a good note, I think this means the Bananas will be just fine of this type of system.

Thank you

I agree with Richard on this . In some local nurseries here the first words out of their mouth is IRON .... But if you stick you finger into the soil it comes up wet . Then they add that its hot and plants need water ! People buy Iron and load the plants down "wammo its green" Still wet and slow growing until someone just leave it alone. Not to many peach trees in Florida but citrus does same thing.
I like to put iron on my lawn so it gets that deep green color

Looks pretty healthy to me. I have peach trees and am going through a fungal infection called leaf curl right now. Ugh!

I wonder why they would suggest iron. IIRC chlorophyll has magnesium and not iron as part of its structure, although there are a lot of important compounds that do use iron. I am not trained in plant physiology which is why I was asking. I know gardeners like to use iron and suggest putting down a rusty piece of metal to supply iron or other metals. I have not asked our county extension office, but due to the presence of iron containing stone and also red clay within our acid soil I assumed that there was enough iron locally for us.

Richard

It's needed in the bio-chemistry (electrolytic in particular) of the plant.

Now the reason they suggest it is generally here-say.

Not such a great practice, plants can suffer from iron toxicity when too much is present. Further, too much iron can inhibit the uptake of other minerals.

Exactly.
