Comfrey: With six-foot deep taproots, comfrey harvests nutrients located much deeper than cannabis can reach.
Its large leaves also act as living mulch, shading out weeds.
Nitrogen-fixing plants can take nitrogen gas from the atmosphere, and with the help of Rhizobia bacteria, store nitrogen in nodule growths on its roots.
Nitrogen fixers are great as a cover crop to prevent weeds and prep soil before planting.
This is by no means a definitive list to cannabis companion plants; there are lots of beneficial plants, and effective strategies vary greatly, depending on each garden’s location and microclimate.
Adding cannabis companion plants will help create a living ecosystem that can better take care of itself, so let Mary Jane continue to be her social self!
