Very interesting, thanks for posting the link. Now I have to pick up all the fallen leaves… and prune my roses all the way down to the soil level to prevent overwintering spores to re-infect my roses!

I haven’t read it all yet… but wasn’t there also research done to show you don’t need to pick up al the dead leaves?

“We are indebted to a scientific study done at the University of California at Berkeley in recent years. It showed that while green leaves can harbor fungal spores, once the leaves die, the fungi die on them.”
