I have a large NG impatien plant. It gets full sun until about noon.
I've always had this type of plant in this spot and they have always
thrived.

The plant is in a large pot. Up until two days ago it looked great.
Lots of flowers, dark green leaves and plenty of buds. Then I noticed
that the leaves started to point upward - almost like they were
folding in prayer. Many of the flowers have faded, although there are
still some and still buds that look OK so far. I put my glasses on
and took a close look. I don't see any signs of insects or fungus.

I water it thoroughly every morning, just as I've done for all my
plants for the past 10 years with success. This is the first one to
show signs of stress.

Clearly this plant is in the early stages of some problem.

Can someone help?

Thanks.

Jane
