Garrett promotes natural organic programs and products. He opposes the use of synthetic fertilizers and toxic chemical pest control products, as well as criticizing some organic products that he believes do not work. He thinks that homeowners, nurseries and landscape companies underestimate the dangers of non-organic solutions, and consults with commercial properties wanting to convert to organic techniques. His philosophy is that the natural organic program works better - in every way. It, for example, saves 40 to 50% on irrigation.
He has written about the plant-derived insecticide Pyrethrum, which is made from the painted daisy ( Chrysanthemum cinerariaefolium or Chrysanthemum coccineum that contain pyrethrin organic compounds which are potent natural insecticides.) One of the common extra ingredients is piperonyl butoxide, which is a synthetic synergist that gives the basic insecticide more killing power. Garrett agrees with the viewpoint of the Journal of Pesticide Reform, which says that in laboratory tests, insecticides made from pyrethrum have: caused tumors in animals; increased the risk of leukemia; disrupted the normal function of sex steroids; and triggered allergic reactions including heart attack and asthma.

Garrett has been the topic in numerous magazines and articles. [2] He is the author of 15 books that range from organic gardening manuals and more technical guides for landscape professionals to texts about insect identification and selecting good quality trees and plants for specific regions in Texas. [3] His design work appears around Texas [4] and until December 2025 had a weekly radio show, when he switched to podcasts. Samples of his books can be found online in Google Scholar. [5]
Garrett runs a website giving information about his approach to organics. [6]
