Consejos de cultivo
Marigold root exudates suppress nematodes — rotate or interplant with nematode-susceptible crops like tomatoes for biological pest management.
Deadhead spent flowers regularly to extend blooming; marigolds flower continuously from early summer until frost if properly maintained.
For lutein extraction (industrial use), harvest at full bloom and dry flowers rapidly; lutein content can reach 8-12 g/kg dry weight in African marigold.
