Green kyllinga is a perennial sedge. It is capable of forming dense mats due to its development of rhizomes. The leaves are dark green and grow up to 6-inches in height. The seedhead is round and has three leaves below it. Green kyllinga spreads by both seeds and rhizomes. Green kyllinga is primarily found from Georgia to south Florida, west to Texas and California.

Cultural Practices

Green kyllinga can adapt to most mowing heights. It develops best in damp low areas. Irrigation should be monitored to prevent areas from becoming excessively wet. Soils should also be modified to prevent excessive moisture.

Herbicide Use

Make your post-emergence herbicide application to green kyllinga that is actively growing and in the seedling to flower stage of growth.
