can my peony fungus spread to other species of plants?

maxineheather(z5 MA)July 26, 2005

I have a peony that came with my house with some kind of nasty fungus- it causes curly leaves, brown spots on the leaves and stem- but the flowers still bloom beautifully, and although the fungus was there last year too, the plant still came back as big and with as many nice blooms. I don't have any other peonies, but I was wondering if the fungus can spread to my other flowers, trees, or vegetables? If so I'll dig it out.

When it comes to the late-season nastiness of peony leaves, not as far as I know.

Some peonies seem to come by the fungus more easily than others. It should not spread to your other plants. You should do two things.

This fall after frost cut the stems down. I leave about three inches of stem above ground as it seems to prevent root rot. The idea as I understand it is a stem cut off close to the root will act as a wick for moisture to enter the plant.

Try and give the plants more air. Keep the surrounding plants low or away from base of the leaves. Less stagnate air less moisture collects on the stems and leaves which provides a better place for the fungus to grow.
