Cedar-Apple Rust : Invasion of Alien-looking Fruiting Bodies

Cedar-Apple Rust

Yesterday we went out to check on ginseng seedlings and found the cedar trees blooming with Cedar-Apple Rust fruiting bodies. It’s caused by a fungus and alternates each year on cedars or apple trees. If there aren’t any apple trees around, or maybe even if there are apple trees, it also chooses hawthorne or crab-apple trees here in the Ozarks for hosting the alternate years.

On the alternate years it appears as small round rust colored circles on the leaves of the host plants. When it gets to the cedar year, it “blooms” with the otherworldly things you see in the photo above.

If you’re growing apples, it pays to grow varieties resistant to this fungus because controlling it or eliminating it is an exercise in futility. The second link is from the University of Arkansas Extension and it lists a whole lot of varieties and their corresponding resistance ability. “VR” means “very resistant”.

About Wild Ozark
Wild Ozark is a nature farm. Mostly we grow rocks. I use those rocks and some of the herbs to make earth pigments and watercolor paints. We also grow native clay that I use for paint and various other things. And then there are the trees. We grow lots of trees. My husband uses some for his woodworking and some for our Burnt Kettle Shagbark Hickory Syrup, but for the most part they stand around creating good air, shade, & habitat for the ginseng nursery.

Follow me on Instagram to keep up with paints, art, and random nature pictures I make in real time.

My art and paints are available on Etsy! But if you're interested in owning a Madison Woods original, follow me on Instagram or FB because sometimes they go out the door as soon as I make the final post to say they're done.

About the voice behind this blog, Madison Woods
I'm a creative old soul living way off the beaten path with my husband in the wild Ozark Mountains. You can find my art on display and for sale at the Kingston Square Arts shop in Kingston, Arkansas. It's a tiny little town and a bit off the path to anywhere at all, but a wonderful ride out to a most beautiful part of our state. Besides homesteading, growing plants & making arts & crafty things, I write books and stories. My rural fantasy fiction, written under the pen name, Ima Erthwitch, usually takes place in a much altered Ozarks.
