Yup ! Same here! Those that I couldn't get to, or forgot, didn't just 'dry up" ,as they normally do, but started to rot! Also, any 'spent" leaves, the ones at the outside of the fan, that yellow a bit and sag to the ground, also open up an area that traps water . Normal years, they just dry up and fall off, but this year, they are rotting off, and taking the next leaf ,or two, with them!...Arlyn
