The Truth About Roundup and Glyphosate – That Every Gardener Should Know

Several years ago I was going to write a post about Roundup and glyphosate, its active ingredient, but decided against it because several very good science-based reports were produced by others. Unfortunately, those reviews were not directed towards gardeners and based on frequent discussions on social media, the message is still not getting through to the gardening community.

My goal in this post is not to do my usual deep dive into Roundup, but instead I want to give readers a summary overview of the facts along with references containing more details. I hope that putting all of the information in one spot will make it a useful tool for discussions in gardening social media groups.

Roundup (glyphosate), Cancer and the Courts – What Does It All Mean

The great debate about Roundup causing cancer had a major shakeup in August 2018, when a court ruling went against Monsanto (parent company is Bayer) and awarded $289 million to Dewayne Johnson because Roundup caused his non-Hodgkin’s lymphoma. The courts have reduced the settlement to $78 million and Monsanto is appealing that.

A few months later two more lawsuits reached the same conclusion.

For the general public this was proof positive that glyphosate, the active ingredient in Roundup causes cancer.

But what are the facts?

Corn Gluten Meal – Does it Work For Weeds?

Corn gluten meal is the new herbicide for lawns. The movement away from synthetic chemical herbicides has left a gap for managing lawns and researchers are scrambling to find an organic solution. One product that is showing promise is corn gluten meal. Its proponents claim that it prevents weed seed from germinating, and if seeds don’t germinate you have a weed free lawn. Sounds like a perfect solution.

There are scientific reports, both for and against the product. Anecdotal evidence from gardeners is also mixed. Does the product work? How should it be used? Are people using it correctly?
