Celery Leaf - Rust...?
I have been growing for a couple of years with varied success but i need some help to identify some problems, so i have taken a pic of some leaves.
I hope someone here can help - the US site has so much more info than the Aussie sites!
This is a celery leaf. I have never had issues with my celery before it's always been great performer, but now, the leaves develop these blotches, and die back, causing the stem they are on to die off too.
I have cut all stems affected and sperayed with a copper spray but it is coming back.
Any tips are very much appreciated.
