on advice of someone directly in hopes of ending the aphids i have soaked all my pots with a Merit based insecticide (Bayer Tree and Shrub) - 1 tsp per 1 quart, is this too strong a solution? the aphids came with Oxalis callosa and O. obtuse - i tried Daconal which scorched the Oxalis leaves under the T-5 lights so i used the insect soap which does very little.
