Question: My vet recommended that I use Frontline as a flea preventive for
my puppy. What is your opinion of this product?
Answer: I am very much opposed to "one spot on the back" products. Anything
powerful enough to kill fleas for a prolonged time with one drop is far too

Bathe the puppy with mild herbal shampoos, spray or clean your house with
orange oil products and apply beneficial nematodes to the lawn and garden.
This program will control other pests, too.
Question: I have serious thatch in my St. Augustine grass. I went to a store
that specializes in organic materials, and the employees recommended
cornmeal. I notice that you recommend sugar and dried molasses on your Web
Answer: That's right. Cornmeal is a good tool, but it is used more as a
disease control than a thatch remover. Organic gardeners don't have thatch
because the rich biological activity breaks down the organic material into
organic matter or humus, which is nature's fertilizer.
Question: Are household cornmeal and horticultural cornmeal the same?
J.H., Cedar Hill
Answer: No. Horticultural cornmeal is the outside of the corn kernel
including the germ and bran. Regular cornmeal, used for cooking, is mainly
the starchy endosperm of the kernel.

Question: Is there a difference between food-grade diatomaceous earth and
the kind used to control insects in the garden? I want to use it for my
horses and am not sure what to purchase.
Answer: There are various kinds of diatomaceous earth. But the only kind
acceptable for pest control and animal feed is natural, untreated and
The Celite brand makes a natural freshwater DE that I use the most. DE that
has been fired and partially melted or contaminated with pyrethrum, as well
as other pesticides or toxins, should not be used.
