I love the color on my 2 Johnson's Blue geraniums, and am used to them flopping after bloom. This year they are flopping before they bloom! The flower heads are there but only 1 or 2 have opened yet. Is there any way I can stop them from doing this? They are covering adjacent plants. Obviously I can't shear them now. Last year I sort of pushed them together with stakes but it didn't look very nice. There are peony cages but they are too wide and tall for these.
