Marigolds not actually repellent
I received a phone call last week from a very confused gardener. Their first statement to me was that they must have purchased the wrong type of marigolds this year because their garden was being eaten up by insects.
Now just a quick history note here. One of the oldest home remedies to repel insects from a garden was to plant a border of marigolds. It was thought that the marigold would repel insects.
