''The best landscaper in Sonoma County for over 15 years.''
At A&J Yard Service, we provide comprehensive lawn care designed to enhance the health, appearance, and resilience of your yard. Our services include:
- Precision Mowing: We ensure a clean, even cut at the optimal height to encourage healthy growth and minimize stress on your lawn.
- Aeration: Our aeration service creates small holes in the soil, improving water absorption, nutrient penetration, and root development.
- Fertilization: Using premium-grade fertilizers, we supply your lawn with essential nutrients to promote lush, green growth.
These services are tailored to Sonoma County’s climate and soil conditions, ensuring your lawn thrives all year long.

Keep your grass at the recommended height for its species. Cutting it too short can stress the lawn and encourage weed growth.
Water your lawn in the early morning to reduce evaporation and allow roots to absorb moisture. Aim for 1–1.5 inches of water per week.
Aeration, overseeding, and fertilization during the appropriate seasons ensure your lawn stays healthy and resilient year-round.
