Am using these for the first time this year. Had always thought they need at least partial shade to thrive, but the tag on this variety says full sun - 8+ hours a day - is fine. Even though I was skeptical about that, I decided to try them for a full-sun planter.

No sooner than I got them in, the leaves started showing these spots. (Not the yellow central color; that's normal for this variety. I mean the bleached areas with tan edges and a few holes.) I immediately thought "sun scald", although I guess it might be some kind of disease. If it's sun scald, I'll just move them somewhere more sheltered. If it's a disease, guess I'll have to pull them and cut my losses... ?

Anyone know what it is?

I know the regular Impatiens has a disease this year but I hadn't heard about the New Guinea ones. In fact, my condo has them planted all over our development. Maybe you just got a couple of bad ones. I would cut off the leaves and see what happens.

Did you check for slugs. I found 3 huge ones eating my petunias. Never thought I had them.

that actually looks like sun scald to me, but then, I'm no expert either.

I passed up buying some because they literally looked sick..just all puny and wilted looking, yet the soil was damp, so I know they had been watered.

For the benefit of anyone who has this problem in the future, I've figured out that it's some kind of disease - probably fungal - that isn't killing the plants, but is disfiguring to the ornamental foliage. As of now, the spots are small and ringed in red. The brown, crusty-looking spots are gone - Must have been a result of cool spring with frequent rains. From a distance you only notice the blooms, so I'm leaving them in for this season, but probably won't use them again.

I used google images to find sun scald on impatiens, and it doesn't look at all like this.
