Our Story
Founded in 1994 by Kevin Bryant, TDI Biological Services in Bessemer is built on a foundational belief: truly sustainable lawn and garden management starts with the soil. We moved beyond conventional chemical treatments to pioneer a biological approach. This method combines microbiology, biology, and sound soil science to address the root causes of weed, disease, and pest issues, rather than just masking symptoms. Our team of licensed specialists uses this knowledge to nurture healthy, resilient landscapes that are safer for families, pets, and the local environment. For over two decades, our commitment has been to provide effective, conscientious service grounded in scientific understanding and a dedication to our Bessemer community.

Question Answers
How does biological lawn care work for my Bessemer lawn?
Our approach focuses on your soil's health as the foundation for a great lawn. We analyze your soil's microbiology and use biological amendments to promote a balanced ecosystem. This strengthens your grass from the roots up, making it naturally more resistant to common weeds, pests, and diseases. Over time, this creates a resilient, healthy lawn that requires fewer interventions.
Can you help with weed growth in my mulch beds?
Absolutely. Weeds in mulch beds often indicate underlying soil conditions. Instead of just spraying, we address the cause. We can apply targeted biological treatments that help create an environment less favorable for weed seeds to germinate and thrive, while being safe around your existing plants and shrubs.
Do you offer traditional gardening services?
Yes, our gardening services are guided by the same biological principles. We focus on building healthy soil to support robust plant growth, improve nutrient uptake, and enhance natural disease resistance. This results in more vibrant flower beds and vegetable gardens that are cultivated in harmony with the local ecosystem.
