You can also go to natural gardener austin, google it and you will get to his site, John Dromgool has a great store and website. He makes and sells the lady bug brand stuff.
Marigolds make great companion plantings, for some reason bugs don't care for them. Garlic spray makes the leaves taste bad to the buggies also.
For fertilizer, depends on if you want liquid or solid. The brand I carry is mostly liquid, but John has both. Worm castings, compost, manure, etc..... all make excellent organic soil ammendments. Be careful on the manure though, since Grazon has been popularized in the hay industry it is passing thru the horses and into the manure of course directly to kill your plants! Check the source, some of them know what they have been feeding, some don't .
