i wouldnt be treating anything this time of year.. in z5 MI ...

look for buds down near the ground ... next years buds ... they should look like little cabbages ... brussel sprouts ....

if this is that type.. and they are all fat an happy .. i would just cut the plant back for the season.. dispose of the cuttings ... and put a big stick there.. so you dont step on the rest ..

if anything harmed this plant.. is was too much water ...i havent watered my pink version in 10 years... and i have had 2.5 years of drought ... rhiz said something a while back about cells bursting in too much rain ...

ken

ps: i think they root rather freely ... i might put some rank cuttings in a pot.. isolate them.. and wouldnt be surprised to find them rooted in spring ... after being buried under 50 feet of snow ... lol ...

Thanks, Ken. I brought a leaf in to a nursery yesterday and the horticulturist advised me to do exactly as you said. She said it is a fungus, especially given our weather this year. She said I could use something natural, like neem or sulphur, but that at this point it wouldn't do much. I did put a little neem on it because I would like to enjoy its blooms, but I will cut it down later this fall. I usually leave my sedums up because I like the way they look in the winter, but I'll get rid of these. They're so little, I'm sure they'll quickly be buried with snow anyway. Good idea on rooting the cuttings, though. I wouldn't have thought to do that, and there is certainly nothing to lose by trying! Thanks again for your time.
