**Lawn Care Tip of the Month – June 2025 | Sammamish, WA:** June is the peak growing season in Sammamish, so it’s crucial to mow your lawn regularly, ideally once a week, to maintain optimal grass health. Keep your mower blades sharp and set to a height of around 2.5 to 3 inches to encourage deep root growth and reduce weed invasion. With the Pacific Northwest’s mild, wet spring transitioning to drier summer days, begin adjusting your watering schedule to early mornings, providing about 1 inch of water per week, including rainfall. Don’t forget to apply a slow-release nitrogen fertilizer in mid-June to fuel summer growth without burning your lawn. A well-maintained lawn this month lays the foundation for a lush, green yard all summer long.
