My daughter and I bought our geraniums from the same market,red white and pink.They were magnificent. Now mine are all full of rust , hers are clear.I live near Wembley she lives near Heathrow.will I have to destroy all of mine and the compost. I usually like to keep some each year to over winter, in the cold green house.
What will I do? I never had 30 geraniums with rust (on the under leaves) in 50 years of gardening,please advise

But why are my geraniums so badly affected and my daughters clear when we bought them from the same market trader, same day same batch.
Many thanks

Rust spores are carried in the wind, so it is a matter of luck if your plants get it or not, so nothing to do where you bought them.

I looked at the RHS site and I'm afraid their advice is to destroy the plants if they're badly affected. What a shame. :-(
