Strawcolored flatsedge is a plant primarily native to North America and the Caribbean. Its range, however, has expanded through introduction across various regions in Europe and Asia. This species has demonstrated a capacity to adapt beyond its original habitats, now found in temperate and tropical zones of these continents.

Native to the United States, strawcolored flatsedge is a perennial that can easily become invasive. In fact, Alaska is the only state where the plant does not grow. As it is only considered mildly invasive, it is not on any invasive plant list. Strawcolored flatsedge's weedy characteristics include its easy spreading habits. It seeds easily in coastal areas, swamps, marshlands, and along rivers and streams. If left unchecked, the weed can disturb other native plants and wildlife and the root system can cause soil erosion. Strawcolored flatsedge is fire-resistant and broad-spectrum herbicides generally don't work. The answer to sedge control usually lies in removing or reducing the source of water.

The best season for removal of strawcolored flatsedge is late spring to early summer, before the plant starts to produce seeds. This will hinder the plant's ability to reproduce and spread. Here are a few organic methods to control or remove this plant:
