Hi Bobbie,
I really appreciate your link and suggestions. I did try the lady bug method. Unfortunatley, although some of them did eat, most left. I timed released them into 2 phases. By the time all of them left, there were still some aphids left and as you know, they multiply more until they are all gone.
So we decided to trash the whole plant before the rest of them gets infected. I think the next option I would like to try is a garlic and water spray and aluminum foil. They sound more natural to my veggie garden and would like to try should the aphids come back.
