As a companion crop, planting a marigold barrier is effective in repelling harmful insects.

The beautiful orange flowers of marigold (Calendula officinalis) are common in many sustainable polycultures. It has been used for many years as a repellent barrier for pests in gardens and orchards.

It is also attributed with the property of strengthening plants growing around it. French marigold naturally produces a chemical in its roots that repels insects, making it very effective in keeping root aphids at bay. In addition, its effects last for years.

Marigold, as a companion plant for cannabis, repels beetles and cicadellids. In addition, it also acts against the Mexican beetle and undesirable nematodes. Its attractive flower attracts nectar-feeding species. It also brings its delicate aroma to make our marijuana crop more discreet.
