There are weeds coming up with the grass in the newly hydroseeded lawn, what should I do?
Do not spray them! Pioneer Landscaping uses government certified seed that is guaranteed to be at least 95% weed free. Weed seeds exist in the loam, are activated by tilling or raking, and then germinate alongside the grass seed. Usually in a matter of a few weeks as the grass matures and fills in, the weeds get choked out. Weed sprays even those designed for use in turf grass can damage young grass plants. Do not use chemicals on a new lawn until at least the second growing season.
