Their leaves are so curl. I think they are ill. I tried the chili and garlic spray without luck.
Can anybody can save them or I should give up to prevent the diseases from spread.
I also find this rust like stuff on the non-curl leaves.
the back indicates a sucking bug.. aphids.. mites.. i cant see..
and they may be long gone... since you already sprayed ...
as they suck the juice out of a plant cell.. it can make them grow curly ...
you might want to check the backsides of the leaves of every plant in the group ....
I found a spittlebug on some basil that looked like that. Any "suds" on the stems or petioles?
