Sue - I am still waiting to have some active rust on my plants to send some leaves to the University. Been a weird summer.
Tina - I didn't even consider the weather or the amount of rain we've had this year. Which makes me think of something else. I water my plants with well water. I don't know how acidic it is. But rain water has a lot of acidity in it. I wonder if that could play a part in the presence or not of rust?
