Step 1 of The Mill 4-Step Lawn Program
Early Spring Pre-Emergent Weed Prevention + Fertilizer
(Apply mid-March – April 15)
Stop weeds before they ever show up and give your lawn the nutrients it needs to wake up strong in spring. This professional-grade pre-emergent fertilizer creates a protective barrier in the soil to prevent crabgrass and other annual weeds from germinating—so your grass grows without competition.
With slow-release nitrogen for steady feeding, Step 1 sets the foundation for a thicker, healthier lawn all season long.
