Turf and Landscape Diagnostics



Weeds can be major pests of home lawns. Due to differences in color, leaf size, shape and growth habit, weeds detract from the natural beauty of desirable turfgrasses. Additionally, weeds compete with turfgrasses for sunlight, soil moisture, nutrients and space. Many weeds can quickly become the dominant species in a lawn. We can assist with weed problems by calling our agent and discussing your lawn.




Submitting Samples by Photos and bringing them in the office

Our office offers diagnostic services to help with a wide variety of gardens in both commercial and individual homeowners. We can't come out to all of our calls, so sending photos of the problems and questions are very helpful in making the troubleshooting easier.

When you submit photos remember to:

Use adequate light and neutral backgrounds. Take several pictures from different angles. In taking pictures of weeds, get the entire plant, the surroundings, and also the roots and leaves. Make sure you include information about the plant such as if it flowers, are the stems round or square, shape of the leaves and any berries or fruit noticed.

When taking pictures of lawn problems, make sure the surroundings are in the picture and light is adequate to show what the lawn looks like in an "overall" picture. Take up close pictures of a lawn sample and be sure to include how long you have noticed the problem, what kind of lawn it is (bermuda, zoysia, fescue). Most of the time, a few pictures and a call to our agent or assistants and we can help you take back your lawn to a beautiful landscape.

Photos should be sent to our agent, Tim Daly at It is always best to give Tim a call at 678.377.4011 and let him know that the photos are on the way and what the problem is. Keep them small so they will download quicker. Any questions, give us a call. 

Live Samples

Bringing in live samples of your lawn should consist of a square of the lawn that is about 4x4 inches. Be sure to dig down and include the roots to about 3 inches deep. Sometimes a soil sample is needed to find out the mineral and pH level in the soil. When you bring in your sample, go ahead and bring in 1 cup of dry soil taken from several places in your lawn and for $8 we can send off the sample while you are at the office.

We are here to assist your with your questions and can be reached Monday through Friday, 8:00am to 5:00pm. Call 678.377.4010.
