Cultivation:

Cyperus rotundus is one of the most invasive weeds known, having spread out to a worldwide distribution in tropical and temperate regions. It has been called "the worlds worst weed"

The difficulty to control it is a result of its intensive system of underground tubers, and its resistance to most herbicides. It is also one of the few weeds that cannot be stopped with plastic mulch.

Propogation:

Cyperus rotundus mainly reproduces by rhizomes and tubers. Hundreds of tubers can be produced in one season at the tips of the rhizome. Tubers require a chilling period to break dormancy and produce a primary basal bulb 1-2 cm (0.39 - 0.78 inch) beneath the soil surface.
