![]() I noticed this spotting on my glui kai a few days ago. It had been in the shade and I moved it to an open, sunny spot. So is this sunburn, or a disease?
Thanks!

![]() The necrosis on the 10 o'clock leaf looks like sunburn and given your description of the situation that is probably the issue.

![]() Has your weather been dramatically cooler lately? Mine do that in the fall in Indiana sometimes after a cooldown in the weather.

When you say "mine do that in the fall..." do you mean glui kai in particular? None of my other new plants in pots look like this, they were all potted then moved out into the sun weeks later (and exposure to cold) at the same time. Nicolas, you are correct that there is sun damage - brown patches - but I've never seen sun damage show up as black spots. Russell |

![]() I learned, many years ago, what the sun can do. I had some Gros Michel that had been kept in a store. One day I took some to a flea market, that was held on the asphalt parking lot of a shopping center. There was no shade at all. Within a few hours, the leaves turned white. The white areas eventually dried up and turned brown, but I've nerver seen any black marks or specks caused by sun.

![]() There are some fungal diseases that do cause black spots maybe Deightoniella torulosa which is called speckle. I'm sure that someone at Auburn Extension would be willing to help you identify it.

![]() I moved some small basjoo out into the sun this summer, and they got identical looking small spots. They started to go away once they got back to partial shade.
I'm sure your problem is sunburn.

![]() Thanks everyone.
Thirteen nights in a row of 20 degree weather "cured" the black spots! Russell |
