Any of you guys that operate a home built dehumidifier kiln have any experience in trying to dry
Persimmon. Any do or dont’s advice gladly appreciated. I know this is tricky wood.

I tried to once and it all turned a horrible blue color.I was told that persimmon has a high sugar content and needs to harvest at the right time of the year.
I was also advised to spray the wood with Lysol to help control the Bactria that will trun the wood blue.
I failed.
I didn’t have a lot invested it was only 5 or 6 trees.
Good luck with yours.

The blue/gray color is from a chemical reaction that involves oxidation of the sugars in the wood in the presence of higher temps and high humidity. Spraying the wood does not affect the chemical reaction assuming that the logs are sawn fresh. If the logs are allowed to lay on the ground for an extended length of time like several months in the summer heat, you will get both the gray stain chemical reaction and you will get some blue staining of the wood from the blue stain fungus. Small logs have a lot of tension in them and will be difficult to dry the boards without bow and twist. Larger logs, i.e. 16” in diameter and larger, behave better, but most persimmon logs are smaller than that.

Thanks Danny for sharing your experience.
Sounds like I never had a chance.
I’ll never mess with persimmon again.
I’ve had very good luck with Leyland Cypress so I’ll stick to that.
