Toney, not sure what your weather conditons are like right now? Aphids usually aren't a problem for semps. I don't see any on the lovely Maria Laach in your above photo.
Once the lady bugs move in the aphids will disappear. Be sure to check any new plants you bring home for pests before adding them to your garden.

I was having a lot of trouble with fungus gnats and mealy bug. No problems this winter. I used it on everything, tender succulents, begonia, tropical hibiscus and adeniums.
I don't use one that has fertilizer in it. I found it online.
