As a homeowner in the Pacific Northwest, maintaining a healthy and lush lawn requires attention to the unique climate and seasonal changes of the region. At Sprinklers Northwest, we understand the importance of a well-manicured lawn and are committed to providing top-notch lawn care services to our customers. In this article, we’ll provide a comprehensive seasonal lawn care calendar to help you keep your lawn looking its best throughout the year.

Spring (March to May)
- Get Your Mower Ready: Before the growing season begins, make sure your lawnmower is in good working condition. Sharpen the blade to ensure clean cuts and prevent damage to your lawn.
- Start a New Lawn from Seed: If you’re looking to establish a new lawn, spring is the next best time after fall. Choose a high-quality grass seed suitable for the Pacific Northwest climate.
- Prevent Crabgrass: Apply a preemergence herbicide to prevent crabgrass and other annual weeds from germinating.
- Aerate Compacted Soil: Aerating your lawn in the spring can help improve drainage, reduce soil compaction, and promote healthy growth.
- Begin Mowing: Start mowing your lawn when it reaches 3 inches in height, and maintain a regular mowing schedule to keep your lawn healthy and looking its best.
Summer (June to August)
- Mow as Needed: Adjust your mowing schedule according to the weather conditions. During hot and dry periods, your lawn may only need mowing once every two or three weeks.
- Water Wisely: Water your lawn deeply but infrequently to encourage deep root growth and make it more drought-tolerant.
- Pest Control: Keep an eye out for pests like grubs and chinch bugs, and take action promptly if you notice any infestations.
Fall (September to November)
- Fall Feedings: Apply a light application of fertilizer in early and late fall to promote healthy growth and prepare your lawn for the next growing season.
- Aerate: If you didn’t aerate in the spring, consider doing it in the fall to improve soil drainage and reduce compaction.
- Continue Mowing: Maintain a regular mowing schedule until the end of the growing season.
- Fall Cleanup: Clean up fallen leaves and debris to prevent thatch buildup and promote healthy growth.
- Overseed Your Lawn: Overseed your lawn in the fall to fill in any bare spots and promote a lush, dense lawn.
Winter (December to February)
- Winterize Your Lawn: Apply a winterizer fertilizer to promote root growth and prepare your lawn for the next growing season.
- Protect Your Lawn from Snow and Ice: Use snow melt products or sand to protect your lawn from damage caused by snow and ice.
