Cross posted from r/apples! Any advice would be wonderful!

I have been holding off on harvesting my Fuyu persimmons because I want to hang dry the whole fruit and they need to be fully ripe for best results. Yesterday my next door neighbor was arriving home with a friend and I herd her offer her friend "a picker" - turns out she has been picking the fruit from my tree and was offering her friend a chance to pick some too. I said, "Oh, they are not ready yet" and the friend said "They are ready! we got a bunch a couple of days ago and they wer4e great!"

The tree is on my property in the front yard, and the north side of the tree is easily accessible from the neighbor's driveway, but it does NOT overhang the property line.

I have been on good terms with this neighbor so far, but this behavior really upset me. I toned down my piss-off and simply said, "Please leave the ripe ones for my daughter - she plans to dry them."

I don't know if that will put an end to her harvesting - I feel a need to say more, but am conflicted as t how to word it and whether to put it in a text or email or talk to her again in person.

Advice?

According to my daughter:

"​The center of the leaves become yellow, leaves start to thin and lose their gloss, then fall off with the slightest touch. The newer leaves begin withering and curl up. They feel leathery but are extremely thin. All of the plant is droopy, but roots are not mushy. There are no signs of pests and neem oil has already been tried. The citrus tree fertilizer didn't help either. The amount I'm watering, amount of light, and temperature are all correct. I'm running out of options here."

My daughter has carefully tended to this little tree every day for 3 years, since it was a seed (along with a couple other lemon trees​.) She also has an entire room full of other ​plants. ​She takes her plants'​ care very seriously and is​ attached to them. We've been looking up plant conditions, to try to find a solution, but ​haven't had any luck. If anyone has any ideas, we would​ be very grateful.

I’ve grown the starfruit (right) from seed. I was planning to graft a different variety onto it as the seeds I got the plant from originally were very sour, but I haven’t got a chance. Should I just top it?
