January: Dormancy and Monitoring
- Perennial Ryegrass in New Hampshire is dormant in winter, so avoid fertilizing or heavy watering during January.

February: Pre-Emergent Herbicide
- In February, mow your lawn to remove any dead or brown grass and help stimulate new growth
- Avoid fertilizing at this stage, but you can apply a pre-emergent herbicide like Scotts Halts Crabgrass & Grassy Weed Preventer to prevent weed germination. For more about preventing weeds, click here.
- Generally, you’ll need to apply 2.5 to 3.5 pounds of the product per 1,000 square feet of lawn area, depending on the targeted weeds and the strength of the formulation. Use a broadcast spreader to evenly distribute the granules across the entire lawn. It’s essential to water the lawn after application, as this will help activate the herbicide and move it into the soil.
March: Spring Fertilization and Aeration
- As temperatures begin to rise in March, apply a balanced slow-release fertilizer like Scotts Turf Builder Lawn Food. Follow the package instructions for application, typically applying 1 pound of nitrogen per 1,000 square feet.
