"The pest resistant properties of marigold are what make it a good companion plant for most crops, including tea. Marigold produces bioactive compounds that are very effective against plant parasitic nematodes that cause root knot and cysts. The presence of marigold, especially due to it's dense growth, supresses weeds that are adverse to tea. It is very shallow rooted, and so it does not compete with the tea roots for nutrients. Also, the biomass generated once the plant has matured is invaluable as organic matter contributed to the soil."
