I always thought mint was good at repelling pests, not attracting them. I know some plants can play a sacrificial role but I didn't think mint was one of them... yet year after year, mint comes back in the same place in a raised bed in my garden. It always looks very healthy until about late May when the leaves start to get infested with aphids (I think).
They suck all the juice out of the mint, leaving the leaves speckled and papery. The lower leaves go yellow / brown. It's usable for cooking but I probably wouldn't fancy using them in a salad (or mojito).
Any tips? I tried putting some marigolds nearby. I also try and blast the bugs off with the hose but there seem to be loads of them.
