Hello. I'm completely new to this topic but read in one of Paul Wheaton's articles that food grade DE is a good ant deterrant around plants and potted plants. Here's my question. The article said that the DE only works when dry. How does one apply the DE to the base plate of a pot and not have it get wet? I assume that after each watering, the water drips down through the pot and onto the plate, ruining the DE.
Would someone please explain the usage of DE with a potted plant. Thanks!
