Hello. I have posted before about this but got no response and my question has now moved on a bit.
Both my french and runner beans grown in a raised bed got rust this year. I believe it started with the french beans which i bought in a local garden centre. Its the second year I've grown beans in this bed having enriched the soil in spring. My crop was reduced and ive pulled them up now but what I'm wondering is how long should I leave it before growing beans in that area again? Is it always going to be a no-go zone for beans?
If its relevant the bed is only raised about 15cms, is south-facing and sheltered by a greenhouse and summer house and fence behind. I have a strawberry bed and a 1m x 1m bed (Ive grown onions and beetroot and carrots in) in front of this larger bed.
I imagine the spores from the rust will be all over this area too.
