Hi, one of my atemoya trees, the leaves has yellowing around the edges. Too much, too little water? Missing nutrients?
I used a moisture tester, and it looks good.

Hey
I can’t see any close up of the leaves, take a look at this resource and then another look at your leaves to see if you can diagnose the problem, it may be just needing a mineral supplement to rebalance despite inherent soil condition http://era.daf.qld.gov.au/id/eprint/1653/6/5probcus.pdf (http://era.daf.qld.gov.au/id/eprint/1653/6/5probcus.pdf)
I found this resource a while back on this forum and saved it, think it’s something every Annona grower should keep in their personal library.

Thanks for the info. I think it maybe be lacking potassium. I don't think it baron toxicity. I am getting some potash in the mail soon. Will try .

If you are irrigating with municipal water, do consider the high pH that your soil will soon have. Potash will exacerbate this and cause a suite of micronutrient deficiencies. I would start by testing your soil pH before applying potash, and if above 8, I would strongly consider acidifying sources of potassium.

True. I am using municipal water...hhmm. The atemoya tree next to this one looks good.

My trees are dropping old leaves like yours.
There is nothing wrong with your tree.

That's a relief. Thanks. I enjoy planting and collecting tropical fruit trees, even gardening. But man, it's very stressful.

One of my trees with fruits is showing severe problem.
Most likely potassium deficiency.
Have you added potassium? How are those leaves looking?

I add some Potash. Not alot. It looks the same. I think it's just natural dropping some leaves. My fruits are drying up, and dropping also. I think it's just natural thinning since I only put it in the ground 6 months ago. I am just hoping for the best. Doesn't look sad my new planted longon tree.
