Gartenmeister flower buds dropping
I've got a question for the pros:
I have a container planting with a Gartenmeister in it. It gets morning sun and is on a drip waterer, but sits under an overhang so it doesn't get much water on the leaves. It looks really healthy but I realized today that it doesn't have any blooms! It looks like the buds have been dropping off before they get any bigger than maybe a quarter inch. It was blooming for a while before this started.... it's got such nicely colored foliage that I totally missed the lack of flowers until today.
Should I look for something? Do you think it's some kind of mite? It's been hot, but not the 100 degree weather others are dealing with!
