I am particularly interested in your aphid control because I think my
Drosera's currently have an aphid infestation. It's also moving onto
the U. longifolia. I'm looking at tiny whitish-yellow 'dandruff' on the
flower scapes and leaf petioles, and they don't move. They must be
aphids, even though they aren't the fat, fleshy looking things I
recognize. (Augh! See what will happen when you neglect them
during one of those intense 5 week winter session courses!)

Did you try immersing the D. capensis in a bucket of water for a few
days? Did it work? I was going to try this approach this weekend.

Can someone dig out the soap/oil mixture in water recipe or suggest
other methods of control?
