Similar to JJ--whack the leaves. Actually, I've gone even more drastic--last fall had an aphid infestation on my D. capensis that did not repond to my frequent drownings (guess I didn't leave it submerged for long enough to get the next generation of aphids). Finally had enough and whacked the whole plant down to soil level. It came back bigger, better, stronger from the roots. * I pulled a few of the non-affected leaves dropped them in distilled water and sprouted 6 new little guys... * *Hang in there--and drown and whack away! * * Mike
