Guardian 13-0-10 is a professional-grade pre-emergent fertilizer designed to do two jobs at once — prevent crabgrass and annual weed seeds from germinating while feeding your lawn for deep green, steady growth.

If you want a clean lawn without fighting weeds all summer, this is where you start.

What Guardian Prevents

• Crabgrass
• Goosegrass
• Poa annua (annual bluegrass)
• Spurge
• Chickweed
• Oxalis
  

Guardian contains .37% Prodiamine, creating a long-lasting soil barrier that prevents weed seeds from germinating.

Why Guardian 13-0-10 Is Different

• Nitrogen for rich green color — promotes steady top growth without excessive surge.
• Slow-release nitrogen — feeds gradually for extended performance and improved efficiency.
• Potassium — strengthens roots and improves drought, heat, and disease tolerance.
• Professional-grade formulation — built for consistent, even results.
• Bio-based — enhance soil structure and naturally support long-term lawn health.

The result is a thicker, darker lawn that naturally crowds out weeds.

Ideal For

• Tall Fescue
• Kentucky Bluegrass
• Bermuda
• Zoysia
• St. Augustine
• Centipede

⚠️ Do not apply if you are planning on seeding.  Prodiamine prevents all seeds from germinating, including grass seed for up to 3-4 months.
