Black Rot? #878635
Asked July 24, 2024, 5:28 PM EDT
It’s my first time growing cauliflower and I purchased the seedlings from Burpee. I’m nervous that they’re infected with black rot and if so, what do I do? They’re in a bed with a few cucumber plants and I don’t want to risk those.

I can't say for sure that it is black rot, but it could be:https://extension.umn.edu/disease-management/organic-management-black-rot
I'd rogue out these plants and not plant a Brassica (broccoli, cauliflower, kale, cabbage, etc.) in the same location for a few years. I'd also buy plants locally (or start your cauliflower from seed).
Black rot is a disease of the genus Brassica. Cucumbers are cucurbits, a different plant family. So they won't be affected by black rot (if that is what this is).
