Yesterday, I tried a new way to feed my D. Capensis and D. Binata
plants.  I opened my Smith and Hawken garden waste composter and
put them inside, amidst a swarm of tiny gnats and fruit flies.
I left them inside for 15 minutes.  Then, I took them out and put
them back in the greenhouse.  Their leaves had a moderate quantity
of gnats, flies, and a few mosquitos on them.  That was the easiest
feeding I've ever tried.  Totally trouble free.  Taking the plants
to the insects really makes things simple.
