powdery mildew ?? do those leaves stay wet and out of the sun for a long time?
It certainly looks like it very well could be! And after reading up on the symptoms, it sounds very likely too.
The plant is in a spot where it receives morning sun up until about lunch, then is heavily protected from the afternoon sun. And the only time the leaves get wet is when it rains (when I water, it's strictly around the base, not on the upper leaves where the mildew is occurring).
However, I'm guessing the temperatures here ATM are playing a big part in it.
"It occurs following warm days and cool nights often being seen in the fall and spring." (http://www.missouribotanicalgarden.org/gardens-gardening/your-garden/help-for-the-home-gardener/advice-tips-resources/pests-and-problems/diseases/powdery-mildew/powdery-mildew-outdoors.aspx)
We've had plenty of warm (humid) days/cool nights here recently. Hell, I'm still sleeping with my doona on... which is just nuts for this time of the year!
First off, i would pinch them...
Second off...is that plant tagged as Halloween???? lol
Yeah, I think a pinching is definitely in order! That is seriously the earliest I have ever had a plant bud.
And yeah, it is tagged as Halloween. NuMex Halloween.
