Timing Sod Installation After Pre-Emergent Herbicide Application

Critical Information Needed

The only reliable answer comes from the lawn care company that applied the products. Request:

• Exact product names and active ingredients
• Application rates and dates
• Label-specified waiting periods before seeding/sodding

Why This Matters

Pre-emergent herbicides vary widely in:

• Mode of action: How they prevent germination
• Residual persistence: How long they remain active in soil
• Selectivity: Which grass species they affect

Legal Right to Know

Most states have "Right to Know" laws requiring service companies to disclose chemicals used on your property. If unfamiliar terms appear on the provided information, research them or consult your County Extension Office.

Never guess—herbicide residues can prevent sod rooting for months, wasting your investment.
