About Us 
Why Biological?
Biological Lawn Care is a holistic approach combining the best of chemistry, physics, biology, and microbiology with sound soil management practices. It addresses and solves weed, disease and insect pest problems at their root causes rather than merely masking the symptoms with poisonous chemicals. Our bioGreen™ biological fertilizer enhances soil biological activity and is designed to progressively use fewer chemicals for a healthier, safer landscape.
About Us 
Great lawn service. Best part is the same technician services my lawn each time. I have a conversation with him each time. I am also assured consistent service.

I’ve been using TDI for a couple of years. They do great and are very accommodating.
– Lindsey P.
TDI does a great job with my lawn care, mosquito treatment, termite protection, and pest treatment. They are professional and always call ahead before arriving. I highly recommend TDI.
– Fred A.
These guys are really great! The routine services are fine, but the cool thing is they hustle out whenever I notice a crabgrass patch popping up, etc. They just got here in less than an hour after I noticed an army worm assault in progress in my yard. Really happy with this service!
– Scott M.
Absolutely outstanding servic! TDI has taken care of my lawn since their early days. When my lawn failed to “green up” this year, they responded the next day at no charge. Now my lawn is green again.
– Susan M.
TDI leaves our lawn looking green and weed-free. We make sure to keep our grass cut and watered, while they do the rest! Our technician does an awesome job every time.
