There are a few last spots of color to greet the cooling air and longer nights. Mums and asters continue their show with a rainbow of colors. Asters tend to come in cooler colors – purples, blues and pinks. Mums pick up the warmer spectrum – orange, burgundy, yellow, red and white. I have a purple aster and a burgundy mum.
My aster has gotten a disease I’m afraid, the leaves are turning yellow and rusty with some black spots and the flowers are mangled looking. I believe it is either a rust or fungus of sorts. A quick Googling of this has made me decide it is not “aster yellows” which tends to change the color of the flowers and can affect more than just asters, like coneflowers. I’ll have to watch it and make a point to check margins, veining and where on the plant it stops or starts.
My mum is has pretty blooms on top but is quite scraggly toward the bottom. To keep perennial mugs in better shape I should have cut them back mid-summer. This causes the plant to keep a more compact and less floppy shape. Of course I’m on the shoulda-coulda-woulda side of things so I’ll make a note for next year. For now, I’ll just cut a few for a cute arrangement on my desk.
