Control of Aphids
I have some tarragon and greek basil which are covered in either whitefly or greenfly. I did have them indoors, but I have read on the blogs that washing them keeps their numbers down so I have just put them outside (its raining), and put them with the other herbs (I've read different herb scents given off act as a biological deterrent).
I bought these plants to eat organically so could anyone provide some futher biological control tips please?
also one stem of the greek basil is withered and brown (see photo). Green Aphids can be seen walking all over it (again see photo). Have they caused this as well. how can I improve/cure it?
