Controlling weeds can be challenging to landscape professionals or home gardeners since landscapes often include a mix of turfgrass, annual plants, herbaceous perennials, shrubs, and trees.
The newly revised publication Pest Notes: Weed Management in Landscapes by Area IPM Advisor Cheryl Wilen, presents an integrated approach to weed management to help ensure weed control efforts are effective, environmentally-sound and economical. This science-based publication includes information on methods such as pre-planting considerations, the importance of weed identification, nonchemical practices such as using mulches and barriers, weed management recommendations in different types of landscape plantings, and updated herbicide options.
