A young friend recently took a look at my garden and suggested that I could grow a few marijuana plants for personal use.
I looked into it, out of curiosity.
Long before I searched for sources of seeds or seedlings, or cultivation advice, I learned that, unless I had a genuine medical need for the herb, growing marijuana (Cannabis sativa) in my garden would be illegal. The related regulations at the local, state and federal levels are full of contradictions and different perspectives, and are in flux.
Many hundreds of illegal marijuana “grows” exist already in the Monterey Bay area, and thousands in California, including many in California’s “Emerald Triangle” of Mendocino, Humboldt and Trinity Counties. The numbers are growing, and it is not difficult to find pot, if one were to be inclined to try it.
Last week, at the 36th annual Eco-Farm Conference, in Pacific Grove, Dr. Andy Gordus of California’s Department of Fish and Wildlife, described and illustrated the impacts of illegal and therefore unregulated marijuana grows in California. The growers are illegally clearing forest lands, damming streams, digging wells that drain streams that wildlife depend on, polluting waterways and killing wildlife with pesticides, leaving mountains of trash, and otherwise being really bad neighbors.
Marijuana plants, like other plants, are subject to a variety of pests and diseases, and growers use a variety of synthetic agricultural chemicals, including some highly toxic materials that are being smuggled in from Mexico. Such chemicals may be sprayed on growing plants, or applied systemically. Also, because rats and other animals chew through plastic irrigation lines, rat poisons are often used.
Marijuana products may be used by inhaling, ingesting, and absorbing through the skin. These diverse forms of use mean that users should ensure that their marijuana does not contain toxic substances. Consumers of marijuana products ideally could rely on the organic label, but at this time there is no such label for these products. Consumers can only rely on trusted sources.
California does not approve any aspect of marijuana cultivation, including pesticides, because it continues to be illegal at the federal level. The federal government also does not recommend pesticides for illegal crops.
In this bizarre environment, California has provided informational guidelines that include a short list of organic pesticides and natural rodenticides that “may be used in and around marijuana cultivation sites consistent with the label.” Visit www.waterboards.ca.gov and search for “Legal Pest Management Practices for Marijuana Growers in California.”

For now, I’ll wait.
During four days last week, the Eco-Farm Conference provided updates about a wide range of organic gardening and farming practices, and related state and federal policies. The short story is that organic, sustainable and regenerative gardening is healthy and expanding steadily. I’ll have more to report in future columns.
