When to Spray Pre-Emergent Herbicides in Kansas?

Depending upon the pre-emergence herbicide product used, Kansas gardeners should spray the product in March or April. Applying an additional application of the herbicide eight weeks later, may be required to kill any weeds that germinate late in the season. Applying a pre-emergent herbicide in fall, controls crabgrass germination the following spring.
