How to save the orange tree?
Is this water log or wrong fertilizer or something else? Help me to save my orange tree and lemon too as they lose their leaves and vitality.

Re: How to save the orange tree?
Hi @John57 . I'm afraid I don't know what's causing the problems with your leaves.
Is the ground waterlogged? When plants are stuck in waterlogged soil their roots can drown and begin to rot and this can begin to show as damage in the leaves.
How much fertiliser have you given the trees, and what sort? Too much fertiliser can cause "fertiliser burn" on leaves, but again I don't know what's actually happening with your trees. If you can give us some more information it might help one of our garden gurus to pin it down.

Re: How to save the orange tree?
Hi @John57 . I don't think that that fertiliser would have hurt the trees. I wonder if it's cold damage.
Just doing some reading online now, it looks as though young citrus trees can be particularly vulnerable to cold damage. This article from an American citrus industry magazine says it's best not to prune, fertilise or heavily water any cold-damaged citrus trees until they have put on a fair bit of new growth in the spring.
This story from the ABC's Gardening Australia looks at using "citrus tents" to protect young citrus trees in winter.
I'm still guessing here, but cold damage could be a possibility. Have you had any frost or near-freezing temperatures recently?

We are also not sure of the reason and may have to wait until this cold spell is over to determine the cause and effect.
Thanks for your feedback.

Re: How to save the orange tree?
Hi @John57,
I'm interested to know what fertiliser you're using. I note you applied "1-cup citrus fert". A cup of Richgro Organics Food would be fine, but a cup of Scotts Osmocote Controlled Release Fertiliser could cause issues.
How saturated is the soil in the area? If you stick a finger in the soil, is it damp for a long period after rain and how long until the soil dries out?

Re: How to save the orange tree?
Mitch
Fertilizer was Richgro
Soil moisture is visible wet on finger. Odd as it is on a small mound rise. The neighboring trees are not so wet.
We are considering drainage across this area. See the slope downwards towards camera and towards the back fence. See the agi drain outlet from the retaining wall garden beds. But I suspect it’s just overall shallow soil 6-12” then clay; across this whole area. Can we remove this orange into a large pot or will the shock seal it’s fate?

Re: How to save the orange tree?
The shock could seal its fate @John57, though it's not looking particularly crash hot at the moment and could be on its way out if nothing drastic changes.
If you were to lift it, you'd want to take all the root ball with it and place it in the largest pot possible. The key is not disturbing the roots at all.
