Evaluation of Non-Chemical Re-Grassing Methods to Transition Lawns to Low Maintenance Turfgrass Species and Reduce Weed Populations
Lawns comprise the greatest single land use other than forests in New York State. While lawns are clearly valued for their visual appeal as well as their function in urban areas, many now desire a lawn that takes less time and money, and uses less fertilizer and pesticides. The most effective means of achieving this shift to lower maintenance strategies is to re-grass a lawn with lower input turf species. This project compared chemical and non-chemical methods of doing so with equipment and materials that are reasonable, affordable, and readily available in the consumer market. In this study, the most effective method of re-grassing was to seed in early September, following treatment with Round-Up to kill existing vegetation. Establishment was equally effective whether seed was introduced by slit seeding or broadcasting, which suggests specialized equipment is not necessary for successful establishment. Scalping did not provide adequate weed control, most likely because it was not severe enough. The clove oil product was not effective against perennial weeds present in the study area, and weeds returned before grass could establish. Multiple applications may be necessary for adequate control.
