It is important to collect a representative soil sample. If multiple sample areas are being tested, we recommend separate tests for each area. Before taking your soil sample, it’s best to evaluate your testing area and divide it into different sections if your lawn's conditions vary throughout.
For example, if your front yard is sunny and your back yard is mostly shaded and does not have great drainage, 2 soil tests may be required - one for the front and one for the back. That way, you get individual accurate readings for each area.
