Problems with tree nuts
I moved to a house that has three pecan trees, but the nuts turn black and fall out on their own.
Is there a solution to fix the problem?
Can I fix by myself or I need to contact an expert?

You don’t say anything about whether leaves are involved, so I wonder if it is pecan scab. Could also be anthracnose (looks less likely from the descriptions). Both are fungal and would require treatment by an expert. Below are 2 articles that you may find helpful:
The 2nd one is generally about pecans; you’ll need to scroll down to the bottom to find the diseases. If you can get this under control, you’ll also see a section on pest management (non-chemical) ways to prevent its return. Unfortunately, when you have hot (& lately) wet summers, fungal issues impact a lot of our plants.
Hope this is helpful.
