I’m having trouble with my rosemary plant. It’s planted outside and is repeatedly attacked by some kind of blight that turns the leaves brown and gray. It eventually kills the entire plant. Anyone know what it might be?

It could be leaf blight caused by fungal growth in wet areas and high humidity. A commercial fungicide treats fungus. I’m not sure the toxicity impacts on an edible plant.

I’ve had the same thing happening. It started to get a white fungus first that was attracting ants. I spray it with Neem now which got rid of the white fungus but now the plant looks like yours so I suspect something else is going on. I’m still spraying it with neem to see if it lives.

Un pot it check soil if white fungi looking stuff is in there repot it make sure not to fertilize much and don’t water the actual stem/plants too much

Are you using tap water or rain water. I had a similar issue and my tap water had increased chlorine which cause my plants to suffer
