Services
Lawn Care Program
Our Lawn Care Program delivers tailored fertilization and weed control to ensure lush, healthy lawns. Using kid- and pet-friendly products, we address soil deficiencies and combat weeds like crabgrass and dandelions. With six seasonal inspections, we proactively maintain optimal lawn health and appearance.
Sprinkler Maintenance
Sprinkler System Maintenance includes seven seasonal check-ups to ensure efficient watering. We perform spring start-ups, fall winterization, and adjustments to prevent dry spots and water waste. Our technicians optimize system performance for consistent landscape hydration.
Perimeter Pest Control
Perimeter Pest Control creates a chemical barrier around homes to deter ants, spiders, and beetles. Our non-toxic sprays target entry points like windows and doors, preventing infestations while maintaining indoor air quality through exterior-only application.
Tree/Shrub Care
Tree and Shrub Care includes disease prevention, insect control, and precision pruning. We enhance plant health and curb appeal while addressing issues like infestations and improper growth. Regular treatments ensure vibrant, structurally sound landscaping.
Equipment Maintenance
Equipment Maintenance services extend the life of mowers and outdoor tools through annual servicing. We offer oil changes, blade sharpening, and part replacements with free pickup/drop-off during winter months for improved reliability and performance.

I have been using Colonial Lawn & Garden for years and highly recommend them. Colonial is very knowledgeable and if they don't know they find out for you and get back to you in a timely manner with your questions/concerns. They stand by their work.

Mike has provided excellent customer service including a detailed estimate of the work to be completed, follow up detail to ensure my mom's lawn and tree/shrub maintenance looks beautiful. The maintenance schedule is on time, dependable and response for repair is timely. I live in another state making help with yard care for my elderly mom a challenge. It's reassuring to know that she can rely on colonial to do a good job, provide good customer service and respond to maintenance needs immediately. Thank you Mike and colonial for all of your patience and efforts!

Colonial has been doing my lawn fertilizing applications and I was very satisfied with the service and the field applicators have been great. I just had Colonial do an aeration, top dressing and overseed on my lawn. I was not totally satisfied with some aspects of the services performed and Eric has refunded my cost of the item discussed. I find it VERY unusual, and impressive, that a company doing business will actually respond to concerns of a customer.
