Dreaming of a thick, green lawn that's the envy of the neighborhood? Lawn Synergy's 13-0-10 Pre-Emergent Lawn Fertilizer can make that dream a reality. This powerful formula not only feeds your lawn with essential nutrients for healthy growth, but it also prevents weeds from even germinating.

Here's what makes Lawn Synergy's 13-0-10 Pre-Emergent Lawn Fertilizer so special:

• Balanced 13-0-10 NPK ratio: Provides essential nitrogen for green growth that is slow-release, and potassium for improved drought tolerance, disease resistance, and stress.
• Powerful pre-emergent weed control: Stops weeds like crabgrass, and other weed seeds from germinating, giving your lawn a chance to thrive.
• 50% stabilized nitrogen: Feeds your lawn gradually over time, preventing nutrient runoff and leaching for a nice deep green color.
• Safe for all grass types: Works on Tall Fescue, Bermuda, Zoysia, St. Augustine, Centipede, and Kentucky Bluegrass lawns.
• Easy to use: Simply broadcast over your lawn and water it in!

This pre-emergent herbicide is effective against a wide range of annual grassy and broadleaf weeds, making it an ideal choice for maintaining a healthy, weed-free lawn.

The stabilized nitrogen in this fertilizer is specially formulated to release slowly over time, providing a steady supply of nutrients to your lawn over an extended period. This results in a longer-lasting green color, improved stress tolerance, and enhanced overall growth without excessive clippings.
