I think I got aphids on my mint and lemon balm.
They are about 2mm or just bigger than a pin head green looking things the have been at my lemon balm and that looks like it about to die.
it is also at my mint plant but the two are approx 3 miles apart.
anyway I was wondering can you use castile soap onion and garlic to kill them I see on net you use onion garlic and cayenne pepper but I would rather ask those who may have had and dealt with the problem...
thanks in advance
PS - I can ask loads questions but this first time I took up gardening so I got a lot to learn I am sorry if I bit of a bug lol
